Open Hopper Feed Pumps with integral Auger Feed Screws are typically used for the processing of mediums with elevated viscosities & high solids content which cannot be transferred via the standard DN/X or JN/X Series. There are 7 construction variants based around the type of product to be pumped, each with their own screws & hopper designs. All can be delivered in either close-coupled or bearing housing supported variations. All hoppers are rectangular as standard and can be adapted to suit installation requirements on request. Nova Rotors Hopper Pumps are available for industrial or food-grade applications.
Nova Rotors’ range of Diamond Series Progressive Cavity Pumps is characterised by a modular design covering numerous models and sizes enabling capacities up to 420 m³/hr and discharge pressures up to 48 bar. The Diamond Series was designed & built with high modularity in mind so that each element of the pump can be specifically selected based on the application requirements and customisation so that even if the product use varies over time the product can be adapted and upgraded to renewed process specifications. As a result, there are a plethora of options and accessories which when combined enable progressing cavity pumps which can be easily tailored to almost any site requirement.
The DH Hopper Pump is part of Nova Rotors Progressive Cavity Pump Range. The DH series is the standard model with rectangular hopper and auger feed onto the hydraulic section. Suitable for up to 18% solids concentration which do not bridge.
The DHS Series features a rectangular hopper & oversized auger suitable for highly viscous materials and up to 28% solids concentration which do not tend to bridge. The screw shaft features a special integrated joint protection system.
The DHP Series features a wide throat hopper with bridge breaker shaft & auger feed on to the hydraulic section. Suitable for materials which tend to bridge or that are easily compressible or which contain solids such as whole fruits, chopped tomatoes, grapes and doughs.
The DHB features a wide throat hopper with double bridge breaker shaft and enlarged auger feed. Suitable for highly viscous materials with solids concentrations up to 35% which have a tendency to bridge. Screw shaft features a special integrated joint protection system.
Similar to the DHS series, the DHSB series is fitted with a special “B” Module which features a special wheel device which directly feeds the auger with materials which are non-flowing with solids concentrations up to 40% with blocks that bridge. This design variant is particularly useful for the transfer of products which tend to plasticise. Screw shaft features a special integrated joint protection system.
The DHS-T series features a rectangular hopper with enlarger auger feed fitted onto the hydraulic section of the pump. Specifically designed for use in the Biogas/Anaerobic Digestion Industry for the transfer of silage with an injection liquid at the end of the auger to increase flowability. The hopper features a rectangular bottom for the collection of stones and debris which can cause undesirable damage to the hydraulic section. There is also an oversized inspection port with quick-release connections for quick and easy removal of solid deposits.
The DHE series has an extremely compact design with large eccentric hopper, is trolley mounted and has been specifically designed for use in the wine industry in conjunction with destemming devices and crushers. Generally used for the pumping of crushed grapes with or without stems. The hopper is fitted with a safety mesh and guard for the drive system which features a bevel geared motor to reduce overall footprint. The trolley handles are designed in such a way to facilitate the mounting of control panels. Level probes can be fitted to the hopper to enable automatic shut-off to protect against dry-running.
