Centrifugal and
positive displacement pumps are the most common pumps used in food,
beverage and pharmaceutical processes.
Centrifugal Pumps
These pumps feature a rotating
impeller and a stationary casing. Centrifugal pumps are well suited to applications
involving variable flow rates. Flow capacity is regulated by throttling
and varying impeller speed.
Positive displacement pumps have
an expanding cavity on the suction side of the pump and a decreasing
cavity on the discharge side. Unlike a centrifugal pump, a positive
displacement pump will produce the same flow at a given speed,
regardless of discharge pressure.
Products typically handled by
positive displacement pumps*:

*Several
factors influence pump selection and sizing. Contact your account
manager or our customer service department to have a centrifugal or
positive displacement pump quoted for your specific application.
