Working function of Centrifugal pump

Centrifugal pumps are classified as rotary dynamic or “kinetic” type of pumps in which a dynamic pressure is developed which enables the lifting of liquids from a low datum height source to a higher position. It consists of a shaft-driven impeller inside of a casing and a motor. The impeller rotates inside the casing. The basic principle on which a centrifugal pump works is that when a certain mass of liquid is made to rotate by an external force, it is thrown away from the central axis of rotation and a centrifugal head is impressed which enables it to rise to a higher level. A centrifugal pump is able to provide much higher flow rates than a standard positive displacement pump.

The main components of Centrifugal pump.

Impeller is a wheel or rotor which is attached through a series of backward curved blades. It is mounted on a shaft which is coupled to an external source of energy which imparts the required energy to the impeller thereby making it to rotate.

Casing is an airtight chamber which surrounds the impeller. It is similar to the casing of a reaction turbine.

Suction Pipe is a pipe which is connected at its upper end to the inlet of the pump or to the center of the impeller which is commonly known as eye. The lower end of the suction pipe dips into liquid in a suction tank or a sump from which the liquid is to be pumped or lifted up.

Delivery Pipe is a pipe which is connected at its lower end to the outlet of .the pump and it delivers the liquid to the required height. Just near the outlet of the pump on the delivery pipe a delivery valve is invariably provided.

A 'foot valve' is a non-return or one-way type of valve which opens only in the upward direction. As such the liquid will pass through the foot valve only upwards and it will not allow the liquid to move downwards back to the sump.

Applications for a Centrifugal Pump

Centrifugal pumps are used for an extensive variety of applications. They are used in medical appliances, welding machinery, transformer cooling, fuel supply, drinking water supply and waste water supply.

BDS Engineering offers a variety of water treatment solutions like Pressure booster Pump, centrifugal pump, Multistage pump, high pressure pump, Pressure Tank and other related accessories.

Does Your Water Pump Need Servicing?

If you have a water pump, sewage pump, centrifugal that needs repair, we can take care of it for you at BDS Engineering New Delhi India. We can repair all pumps, from the smallest submersible pumps to the largest industrial or waste water pumps. So, how do you know if your pump does need to be repaired or serviced?

At BDS Engineering, we know a lot about pumps. However, to most people, pumps are just equipment used in pumping water. Most pumps have an impeller or similar mechanism that moves the fluids, which is attached to a motor that supplies the power. Sometimes this impeller become damage and it will not work properly at that time pumps did not gives proper outcome.

Sometimes pump becomes noisy and create noise pollution,” it means there is a serious problem. If you allow a pump to get to a point where it stops working, repairs will almost certainly be more expensive than if you had addressed them earlier. This can also cause a lot more downtime than routine protection and servicing would have. A silent pump that doesn’t work may be a break in the power supply. A pump that buzzes when it is turned on can be an indication of a break somewhere within the motor.

Even the smallest departure from normal service can become a big problem if it isn’t fixed. For example, if your pump keeps tripping the circuit breaker, it is a sign that it has already broken down to a point of being inefficient and drawing too much power. If your pump has any leakage, it should be addressed immediately.

At BDS Engineering water pump solution, we offer full service solutions for any pumps, from the smallest residential pump to the largest waste-water. We can repair and maintain pumps and facility; we can provide onsite repair and maintenance.
