What is a split case centrifugal pump and how does it work?

 A split case centrifugal pump is a type of pump that uses centrifugal force to generate flow and increase pressure in a fluid. It consists of a casing that is split into two halves along a plane perpendicular to the pump shaft. The impeller is mounted on the shaft and is surrounded by a volute or diffuser, which is a spiral-shaped casing that converts the kinetic energy of the impeller into pressure energy.


The pump casing is designed so that one half of the casing can be removed for maintenance or repair without disturbing the other half. This allows for easier access to the impeller and other internal components of the pump.

The fluid enters the pump through an inlet port and is directed into the eye of the impeller, which is the central part of the impeller. As the impeller rotates, it imparts energy to the fluid, causing it to flow radially outward. The fluid then enters the volute, where the kinetic energy is converted into pressure energy. The pressurized fluid is then discharged through an outlet port.

Split case centrifugal pumps are typically used for high flow rate, low head applications and are commonly used in a variety of industries, including water and wastewater treatment, power generation, and petroleum production.
