DHS-T JHS-T series

Biogas Hopper Pumps

DHS-T JHS-T Biogas pump engineered to increase pumping of solids
This model features a rectangular hopper and an enlarged auger feed screw that moves the product into the hydraulic part. Designed for the Biogas sector and pumping silage with the injection of phase liquid at the inlet to increase pump-ability of the solids. The separate inlet provides the connections for the injection of liquids and has a rectangular bottom for collecting any stones that might enter the hopper, thus avoiding damage to the hydraulic section. Moreover, a large additional inspection port is provided with quick couplings for easy removal of solid deposits from the inlet.

DV series

Vertical Progressive Cavity Pump

Vertical Rotor pump Nova Rotors
The Vertical series is the ideal solution for pumping from wells or tanks. It is suitable for pumping viscous and non-viscous products as well as abrasive or aggressive ones. There are two standard configurations available: the short version and the long version.
The difference is in the length of the installation. The short version is compact, robust, easy to install, the long version instead allows installation in deep wells or tanks, and presents a complete series of dedicated optimisations such as the removable inlet for easy maintenance of the rotor, stator and coupling.
A fundamental characteristic is the support of the downhole support, with a guiding cone which makes the pump very stable and vibration free even in extreme conditions of use.
