What is a Centrifugal Water Pump?

A centrifugal water pump is a machine which uses rotation to impart velocity to a liquid and then converts that velocity into the flow. It includes an assembly of mechanical components which make the functionality of the pump possible. This assembly includes the shaft mounted on bearings, the sealing mechanism, structural components, etc. It has an impeller which is a hydraulic component responsible for the rotation of the fluid to impart velocity. The casing of the pump captures the velocity which is imparted by the impeller and directs the accelerated fluid to the pump discharge point. There are various specifications in which this centrifugal water pump is available depending on the type of purposes.

These pumps are usually specified for higher flows and for pumping lower viscosity liquids. 90 percent of the pumps in some chemical plants will be centrifugal water pumps. These are the most common type of pumps widely applicable in industrial, agricultural, municipal, power generation plants, petroleum, and many other sectors. They can provide both high and low flow rates. This flexibility in the delivery of the flow rate prevents excessive pressure buildup in the piping or requiring a pressure relief valve. These type of pumps can cover a wide range of applications. Submersible pumps are another very common type of pumps which can be submerged inside the water body, Their design comprises sealed components preventing any kind of short circuit.

This pump like any other waterpumpc converts rotational energy often from a motor to energy in a moving field. Some portion of this energy goes into kinetic energy of the fluid. The axially through the eye of the casing and reaches impeller blades. Here, it is whirled tangentially and radially outward until it leaves through all the circumferential parts of the impeller into the diffuser part of the casing. After gaining both velocity and pressure, the fluid reaches the diffuser where the flow is decreased pressure is increased further. The important point in the functioning of this pump is the water is not pushed radially outward rather it is pushed by inertia which is a natural tendency of an object to continue in straight line.
