All water pumps require some sort of power to work, including petrol and electricity. Within our range, we stock electric dirty water pumps, suitable for irrigating gardens as well as pumping contaminated or muddy water from wells, tanks, cellars or basins. As well as multi-use pumps that can be used for clean water pumping applications, including for hot tubs, pond pumps, and or swimming pools.
If you’re considering using an electric water pump you’re probably curious about how exactly they work. In this article, we’re going to explain.
The most common type of electric water pump is a centrifugal pump. Centrifugal pumps use an electric motor and when fluid enters into the casing, it falls on to an impeller. This is the rotating component of a centrifugal pump that accelerates fluid outward from the centre of rotation. As water passes through the impeller, it gains velocity and pressure.
As the impeller spins, curved blades channel water into the centre of the impeller which allows it to flow along to the outside of the blades. Due to the fast flow rate, the centrifugal force compresses the water against the outside of the blade. The pressure this creates makes the water move forward at high speed out of the impeller. This then creates pressure on the outlet side of the pump, pushing the water through the pipe.
What Type Of Motor Does A Centrifugal Pump Use?
Typically a centrifugal pump will use a small DC motor, which sits in a sealed case on the impeller. In the centre of the motor, there are coils around a rotor, and around the coils there are magnets. When the motor is turned on, electricity runs through the coils which creates a magnetic field.
This repels the magnets around the rotor and makes the rotor spin 180 degrees. When the rotor spins, the direction of the electricity in the coils flip, pushing the rotor again and causing it to spin the rest of the way around. Through a series of pushes, the rotor carries on spinning and drives the impeller which powers the pump.
What Are The Advantages Of Centrifugal Pumps?
The biggest advantage of centrifugal pumps is their simplicity. As they don’t require any valves or many moving parts, it makes them easy to produce with many different materials. They can also move at high speeds with minimal maintenance.
