FMH Hygienic Pumps

"FMH Hygienic Pumps" Application Fields

Food Industry Beverage Industry Pharmaceutical Industry

PERA-PRINZ® Hygienic screw pumps for Food and Pharmaceutical industry. Each pump can be customized for a specific application allowing the customer to be served in an optimal way. Several Screws Profiles and several materials available allow them to be optimized for each particular application.
The Screws Pair rotates inside the Pump Enclosure, creating several separate chambers and pushing the fluid trapped inside in accordance with the progression of the screws pitch.
The flow rate is particularly uniform and pulsation-free, and the pumped fluid flows in an axial direction (not circumferentially, as it happens in the centrifugal pumps)
The result of the screws rotation is a gentle movement of the displaced volume, in not turbulent conditions, making it ideal for handling shear-sensitive fluids or liquids easily subject to emulsification.

FMH Twin Screw Pumps with Heating Jacket:
Heating Jacket, completely in Stainless Steel SS316, is used for heating the Pump Casing in applications where the fluid handled needs to be heated during the pumping action, or before starting up the pump. Heating Jacket can be quickly detached from the Pump Casing, for allowing an easy and fast cleaning of the Surfaces.

3p Prinz fmh Series with Heating JacketClean
Fully cleanable in place (CIP) and Sterilisable in place. (SIP)
Cleaning-In-Place (CIP) and Sterilization-In-Place (SIP) are pumps procedures for cleaning and disinfecting without major disassembly and assembly work.
The FMH Twin Screw Pump can be used also as a CIP Pump, with the benefit of eliminating the need of another Pump dedicated only to CIP (and any eventual accessories that would be needed for that).

Pera-Priz® volumetric pumps with one or two pairs of screws

The PERA-PRINZ® FMH Screw Pumps are Rotating Positive Displacement Pumps, externally and internally supported. One or Two Pairs of Screws, which operate without being in contact with each other, ensure a constant flow, pulsation-free, together with a high suction lift capability with very low NPSH values.

Main Advantages
The Trim design is modular with a high degree of interchangeability of parts between their variants, inside the same Pump Series. Each pump can be customized for a specific application allowing the customer to be served in an optimal way. External supports and gears is supplied as a Standard..
