  1. How does a submersible water pump work?

Submersible pumps are pumps that are submerged in water, as the name suggests. Their motor is usually tightly (airtight) sealed and coupled to the body of the pump. Submersible pumps push water to the surface when rotary energy is converted into kinetic energy and then pressure energy. Water gets into the pump by water pressure and is then moved to the surface by pressure energy.

  1. How much is a submersible pumping machine in Nigeria?

The cost of a submersible pump depends on brand, power, output, coil, type, number of wires and durability. An example is Grundfos solar submersible which can range from N750,000 to N800,000.

  1. What size of submersible pump do I need?

The size of your submersible pump depends mainly on the following:
