The DIN-FOOD pump is a hygienic high capacity centrifugal pump (up to 1000 m³/h) designed to cater for an unfulfilled need in the food-processing and chemical and pharmaceutical industries. The applications of the high-flow centrifugal pump include processes in the brewing, dairy and beverage industries in general, as well as in ultra-filtering processes. It can also be used in the textile industry and in some specific processes in the chemical, cosmetics and pharmaceutical industries.

Operating principle
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 a 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.
