Standard design

Twin-wing piston rotors made of special non-galling alloy are

standard. All other media contacting steel components, like the

rotor case, front cover and rotor nuts are in W. 1.4404 (AISI 316L).

With stainless steel gear case and feet, the DuraCirc pump has

an all stainless steel exterior, making it exceptional corrosion

resistant.

The gearbox is as standard designed with duplex shafts and a

strong, long life bearing arrangement. This provides for a very

robust and rigid shaft assembly design – a prerequisite for the very

high volumetric efficiency achieved.

With profiled defined compression elastomers and an optimised

shaft seal location, the DuraCirc is designed according to the

most stringent hygienic design standards and with verified and

effective CIP cleanability.

The pump features a front-loading single mechanical seal, which

allows quick and easy inspection or replacement without the

need to disassemble pipework. Single flushed and double

mechanical shaft seals as well as O-ring seals are available as

options.
