The most common of uses of Domestic Water Pumps is to pump water from the sump to the overhead tank. Although variations can be found in its use, basically the pump is used to lift water from a low area to a high area. This way, the water pump can be seen in use at swimming pools, garden fountains and the likes at a home.
A Measure of Pumping Capacity
Most domestic pumps are given a GPH rating. This is the amount of water in gallons that the pump can lift in an hour. Thus a larger capacity tank or holding area would require a larger GPH to fill with water. The most common of domestic pumps have a GPH rating in the order of a 100. This is considered to be sufficient to meet the requirements of most household applications.
The Head of the Lift
The head as it is more commonly referred to be the height in meters that the pump has to take water up to. Thus, it can be deduced that a higher head would require a more powerful motor. Usually, for the same motor the GPH reduces with increase in pumped height. Most domestic water pumps could easily handle a height of up to ten meters. Beyond this height, the atmospheric pressure does not support a column of water. This then needs a pump that pumps with a pushing action than a pulling action.
The Immersed Pump
The atmosphere does not support a water column of height greater than about ten meters. To overcome this quirk of nature, the pumping action is achieved by pushing than by pulling. Here the submersible type of pumps that are fully immersed in water that can push the water to any heights is needed. Even in this type of water pumps the use of compressor pumps are common. When the yield of a well or water source is low or limited, the lack of sufficient water is compensated by the use of compressed air that helps force the water up the pipe.
The Efficiency of Operations
Generally, when operating water pumps, the efficiency is not that commonly stated. This is because, more often than not, the operation of the pump is done in short bursts and not at a steady rate. Since for a good part of the time, the pump is remaining idle, the efficiency does not come into play. In case, there are domestic operations that need a longer and sustained operation of the pump, then the operational efficiency is then considered.
There are instances when the domestic water pumps are noisy in their operation. This can be particularly annoying at the start up of the pump when a loud and jarring knock is experienced by the user. More so, there are also poorly designed water pumps that tend to vibrate exceedingly while in use. All these would need to be considered while choosing a preferred model of pump.
What seems like a simple choice of a domestic water pump can get really complicated with the choices of performances and different types of pumps available in the market. The mentioned factors would certainly help in getting to choose a suitable pump for the everyday use.
