There is no doubt that owning a water pump can come in very handy for a number of reasons. Maybe you live in an area where flooding occurs regularly and need submersible pumps to help clean up afterwards, or are interested in water pumps to fill your swimming pool. Perhaps you need it for everday use in pumping up water from a borehole or water well.
Whatever the need for purchasing any water pump, you should think about your specific requirements so you choose the correct one:
1. GPM Discharge Capacity
All water pumps are measured in GPM Discharge Capacity which tells you how quickly and powerfully the water is pumped through it. In simple terms, it's the rate the water flows from the source to the discharge point in gallons per minute. If you need it for a job to move lots of water fast, then you need a pump with a higher GPM Discharge Capacity.
2. Vertical Suction Lift
This will tell you what the vertical distance is from the water source to the pump itself. If you are picking up a water pump for something like draining a pond or a flooded basement, this is important to bear in mind so you know the distance is enough to get it to the pump for discharge.
3. Maximum Head Lift
The Maximum Head Lift will let you know what the total height of the pump is from the water source to the discharge point. This figure tells you how powerful the pump is and what distance it can move water over for the job you're needing it for.
4. Type of water pump
There are different types of water pumps, depending on the job you need it for. These include submersible pumps, water-boosting pumps, self-priming pumps, borehole pumps and many more. Research each type and make sure you get the right one for your needs.
Before you dive right in and buy a water pump, take the time to consider the above points and make sure you choose the best one for your individual needs. In doing this, you will get the best product that will be perfectly suited to what you require it for.
