FAQ : What is a water pump ?

You want to know all things about electric water pumps.

But you did not know how to do it.

Then you are in the right place!

In this guide, you will discover the answers to all kind of questions you may have regarding the different electric water pump.

FAQ about choosing a water pump

When you are a novice, it is a bit difficult to choose a pump to power your home and water your garden!

This section will help you to choose your water pump

How to make the right choice for a well pump?

First of all, you should know that a water pump can last for a long time if it is well chosen.

So it is important to consider a few things before making your choice.

This will help to determine the ideal submersible pump that perfectly matches your installation.

So here are some questions you need to ask

  • How to calculate my total manometric delivery head?
  • What flow should I expect?
  • How much residual pressure power is sufficient?

How to make the right choice for a well pump?

We put together in this category all applications where we can place a submerged well pump:

  • A water tank,
  • An underground system
  • A well located between 5 and 20 meters deep.

In order to size it properly , you must estimate the flow in the cubic meter / hour that you need according to the applications: automatic watering, showers, WC or domestic water supply; as well as the MHT the manometric head.

These different elements allow you to calculate the well pump that can be adapted to your installation.

How to make a good choice of a surface pump?

Very often we use surface pumps to draw water from rivers, or to recover water from rainwater or other reservoirs.

In addition, we use it in places where the water is less than eight meters below the level of the pump.

In order to dimension it as well as possible; you must make an estimate of the appropriate flow rate in cubic meter/h according to your consumption.

After the flow rate, you have to add the total head. These two values will determine the surface pump you need to order.

FAQ on water pump maintenance

In this session we will discuss the issues concerning the maintenance of different types of electric water pump.

How to maintain a submerged pump?

As with the surface pump, maintenance is limited. Annual maintenance is generally sufficient.

  • Remove the pump from the water and clean the timescaleor muddy deposits to improve engine cooling.
  • Also clean the check valves.
  • Next, check the operation of the submerged pump: test the rotation of the impeller, check the condition of the SEALs, electrical cables and water level detection probes.
  • Remove the pump from the water and clean the timescaleor muddy deposits to improve engine cooling.
  • Also clean the check valves.
  • Next, check the operation of the submerged pump: test the rotation of the impeller, check the condition of the SEALs, electrical cables and water level detection probes.

Throughout the year, check the engine noise regularly.

In case of suspicious noise (Rolling Stones, vibrations), have your submerged pump checked by a specialist.

How to get a submerged pump out of a drill?

To empty the pipe it would be necessary to empty the well, but if the pump works without water, it can damage.

It is necessary to reassemble everything at the same time by the cable the wire and the water pipe once out of the water it can drain

How to maintain a water suppressor pump?

The bladder tank contains a membrane that is filled with water under pressure. This air pressure must be checked twice a year to prevent the membrane from piercing.

  • The pressure in the bladder tank must be 0.2 bar lower than the starting pressure (pressure switch between 2 and 3.5 bar or 2.5 and 4 bars).
  • Check the pressure gage for pressure and reinflatethe bladder tank with a compressor if necessary
  • Turn off the power supply of the overpressure group
  • Drain the water and then the air from the tank until the pressure drops to 0 on the pressure gage
  • Connect the compressor and inject air until you reach the minimum pressure switch engagement pressure, minus 0.2 bar.
  • Reconnect and re-engage the pump.

Also check the bladder reservoir membrane for proper holding.

If water leaks from the inflation valve or the pump fires too often, the bladder is most likely pierced or cracked. It is then necessary to change it.

How to maintain a lift pump ?

Maintenance of a lifting pump is mainly limited to checking the quality of the water to be raised and the frequency of use. If the pump is used to release waste and charged water, it must be cleaned and checked every two months. It is also necessary to examine the floats, remove residues at the bottom of the tank, and clean the pump and tank with clear water. For the clear water lift pump, it is especially the formation of limescale on the entire mechanism that must be checked regularly.

FAQ About Installing an Electric Water Pump

The procedure for installing the submersible pump is actually quite simple.

Follow these different steps to achieve this

How to install a submerged pump?

The following step-by-step instructions are intended for single and multi-stage deep well pumps as well as screw pumps:

  • You must first connect the pump cable to your deep well pump.
  • Now the PE tube or PE tube (water tube) is connected: If it is coiled, it is best to bend it in a straight line and then close it to the submersible pump using the PE screw connections. By the way: PE pipes suitable for drinking water are identified by their black pipes with blue identification bands (tested by DVGW).
  • Then tie the stainless steel or nylon lanyard to the pump housing using the supplied grommets. The well pump should always hang directly from the rope.
  • The next step is to install the pump control, pressure switch, dry run sensor, etc., and the pressure gage (if you bought them as accessories).
  • Please always remember to install the submersible pump at least 1 m above the filter area or, if not available, at least 50 cm above the ground.
  • If you lift the pump from your well as follows and let it into the well or your cistern (rainwater cistern), hold it only on the lanyard and not on the cable or water pipe. Thanks to the marking, you know when the desired depth will be reached. Also make sure your deep well pump is statically connected to the rope and not to the pump cable or tubing.
  • Rope, cable, and safety line must be securely tied to the wellhead. This can be done with clamps or clamps.
  • Finally, there is the electrical installation: Normally this means simply plugging the mains plug into the socket

How to install a manual garden pump ?

  1. Connect the hose that draws water to the inlet connection of your sprinkler pump. You don’t need any other tools. Do not forget to add Teflon to the thread of the connection in order to have a perfect seal
  2. Immerse the suction hose in the water tank or other water source.
  3. Fill the pump with water to the edge to prime it. Briefly operate the pump to drive out the remaining air and complete the process.

Tip it is important to fill the pump with water to the edge. If this is not the case, the pump will not be primed. If there is air left, the operation will not be optimal.

  1. Connect the garden hose with the fitting to the pump outlet.
  2. Press the foot switch to turn on the pump. Watering is done immediately. Once the watering is complete, just press the switch again to turn off the pump.
