How to Choose Water Pump in Singapore?

A water pump Singapore allows you to obtain water from wells or tanks for domestic use, to drain dirty water or to transport water from one place to another. A motor pump is a machine designed to move a large amount of water and do it quickly and efficiently. This allows us to extract water from cisterns, wells, swimming pools, as well as transporting it from side to side.

To choose a water pump correctly you have to take into account three relevant aspects: the type of water to be pumped, how the water reaches the pump and the power required.

1. What type of water is going to be pumped?

Clean Waters: They are all clear waters, from water for domestic consumption, sea water or waters treated with chlorine, ozone or other liquids. With them can be used most water pumps, including all centrifugal pumps, both surface and submersible.

Waste water: Used or charged water from a toilet, a septic tank, containing suspended particles, leaking or stagnant water.

2. Where does the water to be pumped come from?

The origin of the water will condition the location of the equipment:

– If it comes from a well, a submersible pump must be installed, the diameter of which will depend on the diameter of the well.

– If you come from a reservoir, lake, river or canal there shall be a water pump of surface. There are two types of possible installations:

– In aspiration, if the pump is placed above the level of the water to be pumped.

– On load, if the pump is at the same level or lower than the water to be pumped.

It is important to remember that the surface pumps have a maximum suction of up to 9 m. For higher heights, a submersible pump should be used.

3. What performance should the water pump have?

Once you know the type of water to be pumped and its origin, you must determine what offers better performance depending on the amount of pressure and water needed.

The good performance is measured by the nominal flow rate, the manometric height and the absorbed power that the pump must have to optimize the installation.

The nominal flow rate is the volume of water required in a given time. It is normally expressed in liters / hour (l / h) or in cubic meters / hour (m3 / h). To identify the required nominal flow, the following data are taken as reference.

In irrigation facilities:

When we have an irrigation facility in the house, it is important to calculate well the amount of water consumed by each diffuser or sprinkler. With the data detailed below, you can know the amount of water to be pumped. It is important to know that irrigation is usually divided into sectors. If so, the diffusers of a single sector should be taken as a reference, choosing the one with the greatest need of liters and adding the amount of water consumed by that sector.
