What is a Horizontal Multistage Pump
A horizontal multistage pump is a centrifugal pump containing two or more impellers. The impellers may be mounted on the same shaft or on different shafts, but for the majority if pumps they are on the same shaft.
The fluid flows into the inlet of the pump casing where it flows into the eye of the impeller. The impeller is driven & rotated by mechanical means such as an electric motor or engine etc. The rotation of the impeller creates centrifugal force which directs the fluid along the impeller vane and pushes the fluid to the outer tip of the impeller vane where it enters the stage diffuser.
The diffusers are a type of cutwater which direct the fluid into the suction eye of the next impeller. This process continues until the fluid has passed through each impeller stage. The fluid is then directed out the pump casing through a final diffuser and into the pump discharge.
Each stage that the fluid passes through increases the discharge pressure.
Multistage pumps are used when higher pressures are required which single stage pumps of the same size are unable to attain.
Applications for Horizontal Multistage Pumps
Horizontal multistage centrifugal pumps are used for pressure boosting systems where there is a constant demand for pressure and flow including mining (mine dewatering), industrial, municipal and agricultural (irrigation systems) applications.
Types of Horizontal Multistage Pump
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.
Common uses include water, sewage, agriculture, petroleum and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.
