How to Install a Surface Water Pump?

Installing a surface pump is not at all difficult; you can do it yourself by following the different steps listed below.

Step 1: Place the pre-filter

  • The pre-filter (the filter with the blue cap) protects the pump from dirt by subjecting the water to additional filtration before it enters the pump. The pre-filter to be ordered separately is delivered with a double nipple (brass).
  • Take the double nipple and wrap the two threaded ends with enough Teflon tape.
  • Screw the nipple on the pump suction connection
  • Then screw the pre-filter on the other side of the nipple

Step 2: Filling and connecting the suction pipe

Here are the steps to follow before connecting the suction hose:

  • Wrap the threaded connection of the suction pipe with Teflon tape
  • Fill the suction pipe with water (thanks to the foot valve at the bottom of the suction pipe, the water will remain in the pipe)
  • Connect the suction pipe to the pre-filter (if you do not have a pre-filter, connect the suction pipe directly to the water pump)
  • Place the end of the suction hose (the strainer) in the water source, preferably 20 cm or more from the bottom

Step 3: Fill the pump

Instructions for filling the pump can be found in the pump manual. The preliminary filling is used to avoid the presence of air in the circuit. This is because a water pump has difficulty pumping air, which is normal since it is a water pump.

  • Remove the pump fill screw (located on the top of the pump)
  • Fill the pump with a watering can or graduated beaker until it overflows.
  • Replace the filling screw
  • Preparing the compression fitting

The compression fitting is located on the top of the pump. It allows the evacuation under high pressure of the sucked water.

During this step, you can also connect any accessories ordered separately, such as the dry-running protection or the control system.

Connecting the power cable

Now that everything is ready, all you have to do is record the power cable to the electrical source.

It should be noted that the amperage of the power source must be much higher than that of the pump.

Once you have the proper materials, it is essential that you first check the water source or underground tank and verify that it is clean and in good condition. The inlet pipe connections must be considered in the installation, placing the necessary elbows and nipples, installing a check or non-return valve and a filter at the foot of the inlet pipe.

2- FAQs about the safety measures to take into account when installing an electric water pump

Here, we will discuss about the security measures that are important during installation.

A submersible pump is a machine designed to drain clean water or water containing small solid materials that can work partially or totally submerged below the water level.

This card is valid for submersible pumps driven by an electric motor.

This sheet shows only the specific safety rules that the operator of this machine must follow in order to use it safely.

This sheet does not replace the manufacturer’s instruction manual. The standards contained are of a general nature, so some recommendations may not be applicable to a specific model.

What are the personal protective clothing and equipment?

You should know that it is important to have the right clothes for work. This garment must have cuffs that are well adjustable. It is strongly recommended not to wear items such as: loose clothing, chains, pendants, etc. Because, these objects can get caught in the parts of the machine during installation.

The personal protective equipment found in the safety and health plan must be used for the situations indicated therein. Here are some examples of the most used equipment:

Safety shoes. The use of this type of shoes is mandatory during work. It must have a non-slip / anti-perforation sole.

– Safety helmet. It is very important and mandatory to protect yourself in the event of a risk of falling objects or blows to the head.

How to ensure the safety of an electric water pump during installation ?

  • Fall of the machine from a height

When installing the pump at the bilge site, take into account its weight and center of gravity.

  • Blows by elements of the machine.

Avoid dropping the pump suddenly and prevent it from hitting fixed objects.

Never run the pump while it is suspended in the air.

  • Electrical contacts.

Always use the pump in a vertical position. Do not tip it over while working.

  • Damage to the machine.

The pump should only be used when the level of water to be drained is above the minimum operating level established by the manufacturer. Never run the pump dry.

When the location of the pump cannot be reached directly by hand, it must be raised or lowered by means of a cable or chain tied to the handle. Never suspend it from the electric cable.

  • Blows due to uncontrolled movements of the hose.

When working on structures, special care must be taken that the hoses do not have excessive bending at the edges or may be damaged by them.

Keep the hose as straight as possible. The end of the hose where the water is discharged must always be above the water level to be drained. If the end is below the water level to be drained, it could be the case that the water would continue to flow despite having stopped at the pump.

  • Unexpected start-ups.

Do not immerse or avoid the end of the hose where the water is discharged from being submerged.

Before connecting the electric cable to the socket, check that the engine start switch is off. Once the cable is connected, press the engine start switch.

  • Direct electrical contact.

Do not start or use the pump while other workers are in the water .

Do not keep pump running when strainer is clogged or impeller is blocked.

Stop the pump and clean the dirt causing the blockage.

  • Damage to the machine.

Stop the pump when it makes an abnormal noise or vibrates excessively.

Do not restart it until the problem has been solved.

Stop the pump before removing it from the water.

Press the stop switch to stop the engine.

Then unplug the power cord from the outlet

  • Projection of objects.

Do not leave the machine while the engine is running.

  • Use of the machine by unauthorized persons.

At the end of the day, store the machine in a safe place where it cannot be used by unauthorized personnel.

Store the machine in a clean, dry place protected from inclement weather.

3- FAQ About the Different Types of Electric Water Pumps

Dans cette rubrique nous allons aborder les différents types de pompe en model et les différents catégories de voltages.

Cependant, il faut noter que nous ne fournissons pas une liste exhaustifs de touts les pompes existant.

Néanmoins nous parlerons concernant les plus connu sur le marché actuel.

Where can an electric water pump be used?

Outside of our houses and buildings many pumping teams are working tirelessly.

We will find pumps of different types of all phases of the urban water cycle.

  • Catchment area (rivers; surface water; wells; groundwater)
  • Treatment (water treatment plant)
  • Distribution (supply of drinking water to the urban network)
  • Specific water use: domestic industrial agricultural.
  • Discharge (return of treated water to rivers, seas or other natural channels).

What are the different types of water pump?

These are the kinds of water pump that you can buy and install in your house, land or property:

Electric pump for clean water

It is used for elementary work, such as watering gardens and plants, it is also known as a domestic pump, it extracts water from streams, ponds, rain cisterns or springs.

Combined electric pump for clean water

When the basement or places that can be flooded, this type of pump is very useful for the emptying of these places, it can be used for clean water as for wastewater with solid particles.

Electric pump for waste water

They are very similar to the previous pumps but differ in that they are specially designed to remove dirty water, also to suck particles into the water that can reach the size of 40 millimeters.

Garden pump

Garden pumps  were created especially for the irrigation of gardens of the homes, buildings or other residences.

It is a powerful pump and the water runs smoothly, it can also be used to extract water from cisterns, springs and other water sources.

Submersible Pump

These electric pumps are used within deep water sources, such as wells, fountains and cisterns that are difficult to extract.

Its design is special since it does not rust and does not present corrosion, it can be used more than 30 meters deep, transporting water long distances.

Peripheral pump

The peripheral pumps are known for their domestic use.

They are electric and their function is to raise the water to more than 30 meters high, depending on the model, providing the water pressure you need.

They have a maximum flow of 86 liters per minute.

Centrifugal pump

These types of pumps are used for domestic or agricultural purpose.

Unlike other pumps, they draw water from wells or irrigation in large quantities in a short time.

They have the capacity to move between 120 and 156 liters per minute.

They are electrical and quieter than the peripheral .

What are the different voltages of the electric water pump?

Below we list the different voltages that electric pumps can have: 380- 450 V ; 220-250 V ; 24-12 V (e.g. solar pumps).

What are the power and maximum flow of a water pump?

The power always varies according to the model and the need, being the most common 0.5 HP; 0.8 HP; 1 HP; 1.5 HP; 3 HP.

Depending on the power, it can vary between 30 and 100 l / min.

The source of energy is electricity and depending on the power of the motor. It can vary between 220 and 380 V.

It is important to know that the use of peripheral water pumps is ideal to supply more pressure and flow to small irrigation and home installations, always depending on the use that you want to give it.

4- FAQ about lifetime of electric water pumps

If you want to know how to test a water pump and its lifetime, I advise you to read this section carefully.

What is the life span of a pump?

The service life of a pump is not counted in years, but mainly in the number of starts.

For example, if you don’t have a tank to conserve the water you need to use, you would have to start the pump several times a day.

This type of use will tire the pump and considerably reduce its lifespan.

Hence the advice to always install a large tank of at least 300 liters for domestic use (tap, WC, …).

One could compare this to what is known for a car: Better a car that has driven 80,000 km on a highway than a car that has driven 40,000 km to get bread and children to school.

Finally, we can estimate the lifetime of a pump by taking into account the following parameters:

1) how the water is filtered at the entrance of the pump and its quality.

2) general maintenance of the pump (cleaning with clean water from time to time, winterization, ….)

3) its initial quality in terms of manufacturing (the more expensive it is, the better it is often).

8- FAQ about the test a submersible pump?

When you have a well or a borehole at home, the water is pumped using a submersible pump.

It happens that this pump does not work any more and that you do not have any more the flow of water necessary for the watering of your garden or for your domestic use.

In this case, it is likely that a technical anomaly has occurred in your pumping system.

You must then test your submersible pump to determine the cause of this anomaly and be able to correct it quickly.

In this article, we will tell you the type of test to perform with your submersible pump when a blockage occurs.

Why test a submersible pump?

The test of a submerged pump is done when you want to be reassured of the working conditions or not of your pump.

Knowing how to test your submersible pump saves time and money without having to call a professional directly.

Once the test has been carried out, you are then able to repair your pump or to change it permanently.

This is a way of ensuring that the submersible pump is usable again or not.

When should you test a submersible pump?

A submersible pump should be tested when you notice that there is a fault.

Usually your pump will no longer be able to pump water from the source or the water flow it needs to deliver will be low.

The failure can be caused by many factors.

The first well-known factor is the sand that can get into your pump motor.

Other factors like pumping pipe leaks are also the basis of failures.

How to Test Your Submersible Pump Installation

Testing a submersible pump is usually done by testing the entire installation.

You must therefore:

1 – Test the pump capacitor

The submersible pump capacitor is used to store the electrical charge that helps pump water from the source.

As you know, submersible pump motors use a capacitor (starting or running).

To test a submersible well pump , you must start with this capacitor.

You must first expose the condenser after removing the submersible pump from the water.

Once exposed, you need to short-circuit it using a screwdriver.

Then remove all the wires from the capacitor while memorizing their initial positions to replace them.

Then set the multimeter measuring the voltage. End the test by checking the value displayed by the device.

If this value remains at zero despite the various connections, the pump must be replaced.

2 – Make sure there is no leak

If you perform the capacitor test and it is positive, but the problem persists, you should see from the side of the pipes.

Generally, when installing a submersible pump, it is necessary to check whether the pumping pipe matches the pump.

3 – Check the pumping rate

If there is no leakage from the pipe, the pumping rate may be involved. In this case, it is very low.

You must then perform a test at the suction head or the discharge point height.

How to read a water pump label ?

Horses represent a value to estimate the power of a pump and are expressed with the acronym HP – acronym for horse power- The same action power can be expressed in kilowatts and is indicated by the abbreviation KW .

To find out how much HP data KW corresponds to, a conversion must be used.

  • Knowing that 1 HP equals 0.7457 kilowatts , it will be sufficient to perform the following proportion to obtain an accurate estimate:

1: 0.7457 = The reported number of HP: X

  • Consequently, assuming that the pump to be analyzed is 2 HP, we should perform the following calculation:

2×0.7457 / 1

  • If, on the other hand, we know the number of kilowatts of the electric pump, for example 7, and instead we wanted to know how much HP they correspond to, we should perform this proportion:

1: 0.7457 = X: 7

  • Consequently, the correct calculation to know how much horsepower the pump is is this:

7×1 / 0.7457

Another information that we can deduce by looking at the code on the label is the type of pump power supply. In the case of a single-phase pump there will be a code type 1×220 / 230, in the case of a three-phase model it will be 3×220 / 230.

Instead, we remind you that, if we are interested in knowing the Volts absorbed by an electric pump, they are 240, in the case of a single-phase pump and 400 volts, in the case of a three-phase pump.

Also on a graphic level, to distinguish a single-phase from a three-phase starting from the reading of the label or tag, if you prefer, just look at the final letter which will be M, in the case of a single-phase pump and T, in the case of a three-phase.

In some models the weight is also reported but, unless there is some particular need, it is a rather irrelevant figure, except for the estimate of shipping costs.

9-  FAQ about the different components of the electric water pump

If you want to know more about the different components of an electric water pump, I invite you to read the rest of this section which talks about it in detail.

What are the different components of the pump and their roles?

There are different models of borehole pumps, but all of them have a small diameter, varying between 3 and 4 inches, to match the standards currently in force. Each model is made up of 3 parts: the engine, the hydraulics and the transmission shaft.


The motor is arguably the most important component of the well pump. It supplies the pump with the constant electrical energy required to draw water from the borehole. The pump motor can for single phase current of 240V or three phase current of 400V. Motor power is different depending on the model you choose. It varies from a few hundred Watts to several kilowatts. The PF7 / 74 models from Flux has, for example, a motor with a power of 1100 W. Which well pumps to choose then? It all depends on your needs, the water column and the depth.


The main role of hydraulics is to accelerate and suck the movement of water between the suction and discharge of the pump. It works like propellers to convey water from the water point at the bottom of the borehole to an end-use point, which is the tap.

Transmission Shaft

The propshaft also plays a major role in the operation of the well pump. The role of transferring the power supplied by the engine to the hydraulic part as much as possible is on the transmission shaft.

It is also possible to equip the well pump with a starter set. It is used to fill a bladder balloon each time the level drops. For better use, it is also essential to equip the device with a non-return valve. The function of this valve is to prevent the sucked water from returning to the borehole. You will also need a pressure gauge, which will monitor the pressure in the balloon. To avoid overheating which will damage the pump, it is necessary to install an electrical protection coupled to an electrode.

10- FAQ About the Different Types of Pumps Used in Each Area

There are several types of pumps (of categories, power and characteristics). So it is important to know which type of pump is best suited for each area.

When to use a diaphragm pump?

If the fluid to be transported is very viscous and dense, you can also choose a diaphragm pump.

In general, the double membrane allows the suction and then the delivery of the fluid to be transported. Pumps of this type can run dry, therefore they do not need to be lubricated and are self-priming.

Although they are mainly used in the chemical industry, double diaphragm pumps are particularly versatile and are now used in many other sectors, such as the agri-food, electronics and mining industries.

In general, these high-capacity devices are pneumatically operated. For this reason, if the pump in question is to be used in a factory, you will need to evaluate the capacity of your pneumatic network or, if it is to be used outdoors, equip yourself with an air compressor to keep near the pump itself.

When is it necessary to use a centrifugal pump?

If you need to pump low viscosity liquids and, possibly, loaded with solid particles, you could opt for a centrifugal pump.

Centrifugal pumps are robust devices that generally offer good yields.

These devices can pump high volumes of constant debt and are usually not self-priming.

For this same reason it is necessary to fill the circuit independently before activating the pump.

The use of this type of pump is recommended when you need to feed a wastewater treatment center or to transport dense fluids or cleaning fluids, for example in the petrochemical industry.

When to use a peristaltic pump?

We suggest that you opt for peristaltic pumps, which are the ideal solution for clean , sterile and aggressive fluids , when it is necessary to ensure that the pumped fluid is not contaminated by foreign bodies.

This type of pump allows to realize a precise dosage of the fluid. In fact, the liquid moves inside a tube, rigid or flexible, without coming into contact with the pump body, which guarantees a hygienic pumping solution.

Peristaltic pumps are self-priming. The suction exerted by the tube creates a priming action, which also allows the pump to evacuate fluids that contain air or any gaseous residues. At the same time, however, peristaltic pumps are quite bulky compared to other models with similar flow rates. Finally, since they work in pulsations, their flow rate is not constant.

When to use a diaphragm pump?

If the fluid to be transported is very viscous and dense, you can also choose a diaphragm pump.

In general, the double membrane allows the suction and then the delivery of the fluid to be transported.

Pumps of this type can run dry, therefore they do not need to be lubricated and are self-priming.

Although they are mainly used in the chemical industry, double diaphragm pumps are particularly versatile and are now used in many other sectors, such as the agri-food, electronics and mining industries.

In general, these high-capacity devices are pneumatically operated.

For this reason, if the pump in question is to be used in a factory, you will need to evaluate the capacity of your pneumatic network or, if it is to be used outdoors, equip yourself with an air compressor to keep near the pump itself.

How to choose between submersible pump and surface pump?

The choice between a submersible pump and a surface pump mainly depends on the suction height.

If the fluid to be sucked is at a depth greater than 7 meters, you will have to use a submersible pump: a surface pump, in fact, will not be able to suck a fluid at this depth.

On the other hand, if the suction height allows the use of both pumps, the choice will be made mainly according to the application , the environmental conditions and the frequency of use .

The surface pumps allow for easy access and therefore also easier maintenance.

However, installation conditions can affect pump performance. For this reason it is necessary to use protection against bad weather and any external agents..

11- FAQ about the advantages and disadvantages of an electric water pump

Knowing the advantages and disadvantages of an electric water pump can help you a lot in the choice and use of the device.

So, discover below the advantages and disadvantages of an electric water pump.

What are the advantages and disadvantages of centrifugal pumps?

Centrifugal pumps are equipped with a number of advantages, due to which they are widely popular in the domestic market.

These benefits include:

  • A relatively large number of shaft revolutions. This allows electric motors and turbines to be used as rotation mechanisms;
  • The possibility of a gradual decrease or increase in potency. Thanks to this quality, the launch of the device can be performed with a shut-off valve at the outlet;
  • When several pumps are installed on the same pipeline, the pressure level and intensity of water supply increases significantly;
  • Constructive simplicity;
  • Low cost comparative;
  • Ability to use an automated control system;
  • The fluid can be sucked into the pump from a great height;
  • The efficiency of these devices is about 0.6-0.8;
  • Reliability of operations.

The disadvantages of this class of pumps include:

  • The probability of an unstable water supply, which changes in the event of an unstable operation of the electrical circuit.
  • At the start-up, the working capacity of the centrifugal pump must be filled with water. Often, water must be poured into the device if the liquid level does not reach the inlet pipe.
  • The functional characteristics of the mechanism can significantly decrease in a situation where the air mass enters the spiral, in this case the bearings and other components fail faster.

What are the advantages and disadvantages of the submersible pump ?

As the name suggests, the submersible pump is intended for use in submersion, to pump water or to remove any liquid that needs to be removed. Just like other pumps, a submersible pump is available in a wide variety, each type having specific applications.

Advantages of the Submersible Pump

While this is not a technical advantage, submersible pumps are designed to be tightly contained underwater.

Thus, they are completely waterproof and the risk of leaks and electrical contacts are eliminated.

Thus, the pump will not suffer any internal damage and repair costs will be reduced to a minimum.

The second advantage of a submersible pump is its interaction with water. This is because the fact that the pump does not use suction to convey the water to the pipes or the pipes, the pressure is optimized. This allows the water to travel at a greater distance, which can be useful for large farms.

The biggest advantage of a submersible pump, however, is that, unlike other types of pumps, they do not need to be primed before running. This not only saves time, but also reduces the risk of overwork.

Disadvantages of the Submersible Pump

The biggest disadvantage of a submersible pump is that it is difficult to identify and repair damage such as a break.

This is because if the pump loses its integrity and starts to leak, the components can start to corrode without any sign being visible since they are submerged. Although these cases are rare, if they do occur, damage may be identified too late.

The second downside, while pretty obvious, is the cost.

Indeed, due to their technical nature and all the safety groups required, submersible pumps tend to have a higher cost than ordinary pumps.

What are the advantages and disadvantages of the garden water pump ?

When looking closely at the advantages and disadvantages, you should start with the positive properties of the pump.

The advantages of the pump

  • First and foremost, the device is quite handy.
  • There are many offers, but for domestic use a garden pump is significantly smaller and more compact than other water delivery systems.
  • This also results in a lower price , which is why such a pump usually costs up to 30 percent less.
  • Another advantage is that you can use the device to meet a wide range of requirements .
  • This is because there are different sizes and types that can be used for numerous areas.
  • The flexibility of the device is further improved through variable connection options and different installation positions.
  • Another plus point is that you can use the garden pump for many years . This is due to the optimal impeller and the housing construction. These are very durable and low-wear, so that they can withstand high loads without any problems.
  • However, should problems arise, repairing the pump is often child’s play. This is because most of the parts can be replaced.

The disadvantages of the garden pump

You will not only discover advantages when you look at the advantages and disadvantages of the centrifugal pump.

There are also some disadvantages associated with this pump.

  • You can only use the garden pump for small amounts of liquid.
  • This is due to the fact that the pump delivers the liquid directly and then dispenses it again.
  • However, if you pump more liquid with the pump, this can lead to problems.
  • This switches itself off and on more often, consuming a lot of electricity.
  • At the same time, the motor can be damaged by constantly switching it on and off.
