Centrifugal pumps are the most commonly used pump in many industries. This type of pump is mainly used in agriculture, municipal water and wastewater plants, industrial, power, petroleum, mining and many other industries. Simply put, this pump uses centrifugal force, through its impeller, to transfer fluid from one location to another.
All centrifugal pumps include a shaft-driven impeller that rotates (usually at 1750 or 3500 RPM) inside a casing. Liquid flows into the suction port (inlet) of the casing and is thrown to the outside of the casing and then exits the discharge port. The velocity imparted to the liquid by the impeller is converted to pressure energy or “head”.
