Water Pumps

Grekkon Limited sells and installs many types of water pumps for irrigation.

How many types of water pumps are there?

1. Surface pumps

i. Solar water pumps. These are booster pumps

ii. Electric pumps. Both booster pumps and large surface pumps

iii. Generator pumps. Both petrol and diesel driven types

2. Submersible pumps

i. Solar-powered pumps

ii. Electric pumps

Generator Water Pumps

Generator pumps are portable, easy to use, and come in various sizes according to the pump’s power. They require regular servicing for optimal performance,  and are prone mechanical damage.

 These are small inexpensive pumps powered by an AC electric current to pump low water volumes. Booster pumps are used to irrigate small fields or for domestic water use. It is placed on the surface.

It is an easy pump to install, operate and service. They are portable and require low voltage to operate. The disadvantage is that farmers in off-grid locations cannot use them.

In these areas, a solar or generator version will be used because sunlight and fuel are easily available and accessible.

Generator pumps are the most common pumps used in Kenya by large, medium and small holder farmers. This is because they are easy to move about, are inexpensive and common in many outlets. Easy availability of fuel all over the country makes it convenient to use them. It is simple to operate and service for any farmer. They are surface pumps further categorised as;

• Diesel pumps
• Petrol pumps

Both categories have the following pumps;

i. Low pressure, high water volume

ii. Low water volume, high pressure

iii. High water volume, low pressure

Solar

Grekkon Limited’s surface solar pumps use an electric current generated from a series of solar panels. They are low pressure, low volume pumps that are used to pump water from shallow wells or rivers. Our surface solar water pumps are single-phase pumps because they use low power.

They require a single panel supplying 200-280 kw to operate. They are affordable and support irrigation in off-grid locations. A good illustration is in drip irrigation systems in flat lands where additional pressure is necessary. This pump will create pressure to move water over large areas in the farm.

Electric

Our submersible electric pumps are powered from the power grid. We have a choice of submersible electric pumps that pump from within the water. These type of  water pumps deliver water from deep wells and boreholes. Our submersible electric pumps are further categorised according to power supply. Here, we have 3-phase pumps which are larger and require greater power, and single phase pumps which use less power.

These require low maintenance through service once every five years. Their stainless steel cover preserves them for decades without rust. Their disadvantage is that they cannot be used in off-grid locations. In these places, their solar powered versions work best.

Solar Water Pumps

Grekkon Limited’s solar pumps use an electric current generated from a series of solar panels. We have a choice of submersible solar pumps that pump from within the water. These types of solar pumps are used to pump water from deep wells and boreholes.  Our submersible solar pumps are further categorised according to power supply. Here, we have 3-phase pumps which are larger and require greater power, and single phase pumps which use less power.

These are expensive to install but save in the long run being no periodic electric bills. They use direct sunlight energy for seven hours daily. A converter is used to make this into into an electric version when needed. For example during the rainy or cold season, the hybrid pump will use electricity from the grid. During sunny days, sunlight will be used.
