There is a wide variety of water pumps available to suit different purposes and needs. A general rule of thumb a water pump is mainly utilised to minimise downtime from heavy rains and to move water from area to another.
Types of Water Pumps
There are just a few main types of water pumps; each serving a specific purpose within a business or home. However, all types are in charge of moving water from one area to another continuously.
Well pumps: This type of water pump is used to push water from an underground water source through pipes that connect to a home of business. Well water pumps are available in a variety of horsepower units. The benefit of this type of pump is that you can select a pump with the right amount of horsepower to fit your individual needs. You can also get well water pumps with enough horsepower to supply more than one home or business.
Pressure tanks: This type of water pump regulates the pressure of the water as it enters the pipes in your home. It is perfect for climates that have all four seasons. Reason being that seasonal changes can modify the pressure of your water. For instance, in the spring the melting snow will affect water pressure.
Sump pumps: This type of water pump is best for removing excess water due to rain, melting snow and floods. The sump pump is typically installed underneath a house or in a basement area where excess water can build up. The float inside the pump is activated when water reaches a certain level, which turns the motor on. The motor then spins the blade, pushing out the excess water up a drain hose and outside the building. Another benefit of submersible pumps are their ability to manage large amounts of water and be submerged without the hazard of electrical shortages.
The Main Types of Water Pumps
There are two main categories of water pumps; positive displacement design and centrifugal pumps. Both types are available in a variety of options that can be tailored to your needs.
Positive Displacement Water Pumps: This type of water pump supplies a fixed amount of flow. They are ideal for buildings that have sensitive solids or need to manage high viscosity liquids. The advantages of this type of water pump include high efficiency and removal of air in the lines. For best performance, the clearance between the outer edge and the rotating pump needs to be close.
Centrifugal Water Pumps: This type of water pump uses a rotating impeller to move water through the pump. It then pressurises the discharge flow. The centrifugal water pump can be used with all liquids including liquid with low viscosity. It is the ideal water pump for thin liquids and high flow rates. The advantages of this type of water pump includes a boost in pressure from the intake line, has a continuous pressure source which offers a fire protection system, perfect for hot water pumping by moving water in a closed system, has an automatic switch controlled by the float and no suction lift is needed. For this system works best when the liquid recirculates avoiding overheating caused by low flows.
