Water pumps in Kenya by Grekkon Limited are varied for different purposes. This provides a wide choice to select from for growers according to irrigation use. Below are water pumps by Grekkon Limited

Water pumps in Kenya

Categorisation

1. By displacement

1.1. Centrifugal pumps work through centrifugal force to drive water that enters the impeller. They use the rotational energy from the spinning impeller to produce hydrodynamic energy

1.2. Positive displacement water pumps use a piston, a diaphragm, or a rotating cog or gear to mechanically move a fixed volume of water through the pump chamber

An electric centrifugal water pump

2. By Location

2.1. Surface pumps suck water through an inlet pipe, then pump it out from an outlet pipe. They are set horizontally on dry surface. Theses are; electric surface pumps including booster pumps, solar surface pumps, diesel and petrol generator water pumps

A diesel water pump

2.2. Submersible water pumps work under water in wells. The size and power depends on the well depth, and discharge rate. They are either solar or electric powered

3. By power output

3.1. Electric motor powered pumps are either electric (AC current), or solar (DC current) water pumps

An electric surface pump

3.2. Generator powered water pumps are either diesel or petrol types. These are available as high pressure, high volume, low pressure and low volume

What To Consider When Buying Your Water Pump

1. The head/ pressure rating

This is the vertical pumping distance in meters or bars. The higher it is, the higher the pressure needed, and the more powerful is the engine or motor. Fuel engine (generator) or electric motor power is horse power (Hp), or in Kilowatts (kW) for the latter

2. The flow rate

This is the amount of water pumped evacuated per unit time. It is in litres per minute or per hour. The higher it is, the larger the water pump inlet and outlet size

For agricultural use, PVC or HDPE water pipes are connected to these pumps. The pipes evacuate water to the crops

3. The power rating

The motor or engine size provided in kilowatts (kW) for the former, and in horse power (Hp) for the latter determines the water pump’s efficiency. The larger the flow rate and the discharge, so will the engine or motor be
