Price Guide (Inc GST): POA

The Prolac S pump is a sanitary centrifugal pump that meets the highest sanitary requirements for use in the food-processing and pharmaceutical industries.

Some of its uses include processes in the brewing, dairies and beverage industries in general, and with the appropriate options it can also be used in complex applications such as evaporators, concentrators, distillation towers, decanting of syrups, and purified-water loops in the pharmaceutical industry.

Operating principle of PROLAC S Centrifugal Pump

Housed inside the casing, the impeller rotates in conjunction with the pump shaft .With this arrangement, the impeller blades convey energy to the fluid in the form of kinetic energy and pressure energy.

This pump is not reversible by simple reversal of the direction of rotation. The direction of rotation is clockwise when the pump is viewed from the rear side of the motor.
