There’s a lot to keep in mind when shopping for the water pump. We’ve discussed the most crucial points below. Keep reading.
Depending on the application, the type of pump you need to differ. There are countless types, so decide carefully. Probably the most common use for the units is dewatering large bodies. Another common use would be getting water out of wells. A less common use would be to increase water flow in fixtures.
Gas vs Electric
Electrically powered water pumps are usually 120V. But you can go up to 230 V if you want. There’s no point in purchasing an electric pump if you don’t have the proper wiring to support it – research this. Electric options are more suitable around the house as a result.
Gas alternatives are powerful. You’ll almost always see them at farms and irrigation sites. Due to their sheer power, up to 750 gallons of water can be expelled out of a body. Just know that they can produce carbon monoxide – don’t use them in closed premises.
Make note of the pump’s suction head; it is the vertical distance of the water source to the pump. If the vertical distance is a lot, more force would be needed to pump the water – you’d be fighting gravity. The suction head is especially important if you’ll be draining a water body, or you’ll be taking water from a deep well. It wouldn’t be that important if you’ll be using the device on a hose.
Total Head Lift
The suction head would tell you the vertical distance from the power source to the pump. But the Total Head Lift would tell you the distance travelled to the final destination. If you purchase a pump with a large THL, you’d be purchasing a powerful unit. This is what you want if the device would be attached to a fire-hose.
Gallon Per Minute (GPM)
Even if you purchase a unit with a large Total Head Lift, it might not be worth your time. The pump that would be needed for the job may need to suction a lot of water. This isn’t possible for some units. You’d be able to know the quantity that can be moved to and from with the Gallon Per Minute reading.
Inlet & Outlet Size
Will the pump you’re interested in fit the inlet you’ll be inserting it on? Make sure that the outlet would match the pump as well. As you can imagine, options meant for homes have the smallest inlet and outlet sizes.
How do you find the right pump for the job? All the points we discussed would help. From everything talked about, probably the most crucial would be whether the unit would be suitable for the task or not. It should have a suitable GPM as well. It won’t be able to suction that much liquid otherwise. Also, decide between gas and electric options – gas ones would provide the most power. However, they can produce carbon monoxide.
