PROGRESSING CAVITY PUMPS Hopper Industrial Series Biogas Pumps Series with hopper an auger feed screw to convey directly the product to hydraulic part, are the ideal machines for pumping viscous and non-flowing, with a very high solids content. The DHS-T e JHS-T series are the hopper rectangular version with increased auger feed screw to the hydraulics. Versione realizzata per il settore Biogas per il pompaggio di insilati con iniezione di fase liquida nell’imbocco per migliorare il pompaggio della parte solida. L’imbocco separato, oltre a prevedere i collegamenti per l’iniezione liquida ha un fondo rettangolare per la raccolta dei sassi che possono entrare nella tramoggia e che vengono trasportati dalla coclea. Ciò permette di evitare danni alla parte idraulica. Inoltre è presente un ampio portello di ispezione supplementare ad innesti rapidi che consente l’estrazione dei residui solidi nell’imbocco con estrema facilità. DHS-T series: the drive is coupled directly to the pump via a flange. This solution is extremely cheap and compact, considerably reducing installation costs and simplifying maintenance. The stress generated by the hydraulic part is supported by the drive itself. Each drive used is adequately selected based on their specific technical parameters and are subject to numerous duration tests with heavy loads. DHS-T series JHS Series: the drive is connected to the shaft inlet via a coupling joint. This configuration is the best solution in terms of performance and durability. All the stress generated by the pump is absorbed by the bearings in the housing. These bearings have very high resistance against loads. They are assembled with extreme precision on the highest quality manufactured parts. It is the best solution when you want to guarantee duration and reliability, yet with greater installation space requirements. The bearing housing designed by us is modular and can be installed after a pump with the DHS series block housing. It is state of the art for this type of installation.
