Single Screw Pumps | DIAMOND

Progressing Cavity Pumps HX series

Sanitary design for food and pharmaceutical industry

The DHX hygienic pump series with hopper an auger feed screw to convey directly the product to hydraulic part, is the ideal machines for pumping viscous and non-flowing, with a very high solids content. Suitable for pumping substances poorly flowing up to 18% of dry substance which does not tend to form a bridge.
The complete sanitary design, in compliance with standards EHEDG and 3A, ensures maximum sanitization. These pumps are top rated for " Clean In Place" and " Sterilizing In Place". The geometry of the pumps is designed specifically to allow drainage and avoid dead zones. Each component is manufactured with the highest level of finish and utmost cleanliness.
As well as the parts that come in contact with the product, the block and base plate (when requested) are made of stainless steel (standard in AISI 304).
The available fittings include DIN 11851, DIN 11864, Clamp ISO 2852, Clamp ASME-3A, Clamp DIN 32676, RJT, SMS 1145 and lastly Garolla and Macon for the wine industry.
The complete range of pumps can be manufactured with block construction (DHXO SERIES and DHXC SERIES), bearing housing with independent shaft (JHXO SERIES and JHXC SERIES) or bearing unit with plug-in shaft (FHXO SERIES and FHXC SERIES).

Variants

DHXC Series

The DHXC series is the standard DN series hopper pump. It is the solution that combines excellent sanitizability characteristics thanks to the casing design completely free of dead zones and stagnation, together with the performance of the patented pin joint of the Diamond series. The lubrication of the joint is independent of the pumped product, so it is also suitable for abrasive fluids. 

DHXC Series

Series DHXO

The DHXO series is the pump with an open-ended hopper. ' It is the solution with the best characteristics of sanificabilità thanks to the design of casing and rotators completely free of dead zones and stagnation. The joint, of type with pin has been appropriately dimensioned to guarantee a long life. The lubrication of the joint is guaranteed by the product itself thanks to the open type design, therefore it is suitable for non-abrasive fluids. Performance is greatly improved in the pumping of lubricating products.
