Pressure pumps are electro-mechanical devices that can move or lift water from one place to the other. There is a huge range of pumps to choose from for your household needs and you need to select the one that best serves your purpose. Domestic pumps often consist of a spiral casing, an impeller and an AC electric motor. This pump draws water from the mainline through the impeller, applies kinetic energy to it, and moves it to the water storage tank. Pumps meant for domestic applications have a lower power and flow rate than agricultural, industrial or commercial pressure pumps. If you are looking for a pressure pump for your house, then here is a quick buying guide for you.
Check the Flow Rate: Figure out the number of outlets that are supposed to be working at the same time. Remember, different outlets may have different flow rates: a shower dispenses around 10 litres per minute, while a toilet dispenses 6 litres per minute. A pump with 25 LPM flow rate would be sufficient for a small cottage, while a large home with a family of 10 people would require a pump with a flow rate of as much as 90 LPM or even more.
Find Out the Pressure Required: An ideal pressure is 300 kpa for households. But if you have so many small or long pipes or if your water tank is situated at a distance from your house, then you may look for pressure pumps with more water pressure. Most single storey buildings suffice with a pressure of 300 kpa, but multi storey buildings may need pressure of as much as 500 kpa.
Look at The Types of Pressure Pump: There are many different types of pressure pumps that you can go for, including jet pump, multi-stage pump, variable speed pump, submersible pump etc. Jet pumps are perfect for suction applications, and handle air much better than other pump types. Multi-stage household pumps are efficient and offer ideal flow and pressure for medium to large sized homes. Variable speed pumps are new in technology. They have variable speed motors that are high performing as well as energy saving. Such a motor runs at the needed speed only, thereby saving electricity costs. Submersible pumps can be placed underwater, in case you want to install it in your water tank or in your bore.
Find the Type of Controller: The job of a controller is to control the pressure, allow dry running, and provide constant pressure. It automatically turns on or off when there is requirement of water and does not turn on if water is not coming from the source. You may also find a controller that is a combination of tank and pressure switches, both of which work with each other to offer automatic pressure.
Specifications: Before you finally buy, you need to find out other specifications and details of the pressure pumps. Look at the head, which is the height up to which the pump has capacity to lift water. You have to choose the head as per the height of your building or the number of floors in your house. Also consider the inlet and outlet size, which is the diameter of the delivery pipe and the suction, which must be at par with the storage tank pipe and water supply pipe. The material of construction should also be kept in mind, as a pressure pump with CI motor body and brass impeller is the most durable and long-lasting.
If you are looking for good quality pressure pumps for your household use, then check the above mentioned points to make an informed decision.
