By having a borehole, you can do away with a lot of uncertainty and ensure that you have ready water whenever you need it. As much as they are reliable sources of water on the farm, boreholes rely on good water pumps to optimise supply to any point where water is needed. Centrifugal pumps can suck up water from boreholes and distribute to different storage points. If you are looking to buy one for your farm, here are some of the considerations that you should make:
Is The Pump Submersible?
Do you need a pump that can be installed under the surface of the water to help you reach deeper into the borehole? Some centrifugal pumps can only work when they are installed above the surface of the water while others can function both above and below the surface of the water. Preferably, you should go for a centrifugal pump that works in both instances. When buying, you should ask for a submersible pump such as a rotary centrifugal pump. Besides their ability to pump water in both situations, submersible pumps have been designed to withstand damage and corrosion when you immerse them in water.
Is the Pump Limited to Clear Water?
There are many types of centrifugal pumps that meant for clear water. Such pumps, especially the submersible ones, are ideal for pumping rainwater harvested in tanks rather than water from boreholes. Even though water from boreholes may be clean, it is likely to come into contact with soil particles, which are then taken up by the pump. This can clog up the suction or outlet pipes, necessitating costly repairs. For a borehole, you should go for a pump designed for water with particles and debris.
How Powerful is the Pump?
The turbines of the centrifugal pump you buy should gather enough momentum to suck and push pump water over a certain horizontal or vertical distance. To avoid buying one that will not meet your expectations, you can use a tape measure to gauge the vertical or horizontal distance that the water will travel. Note the distances so that your vendor gives a pump that is powerful enough.
Does It Have A Float Switch?
A float switch is a safety device that will turn off the power supply when the water levels drop beyond a certain level, stopping the motion of the turbine. This keeps the pump from running in a borehole that's possibly been sucked dry. When choosing, look out for one with this safety device.
