Our Hopper Pump, part of our Progressive Cavity Pump range, is the ideal solution for processing highly viscous, solid-laden fluids across industrial and food-grade applications. With a food-safe design, this pump ensures optimal hygiene and efficiency. Available with multiple configuration options, including ATEX-rated models for hazardous environments, the Hopper Pump delivers exceptional versatility and performance. Some of the liquid handling capabilities of these variants includes:
- DH/DHE model: suitable for up to 18% solids concentration without bridging
- DHB/DHP model: for even higher solids concentration of 35%
- DHS model: for highly viscous materials up to 28% solids
- DHSB & DHS-T model: for non-flowing materials with solids up to 40%

Variations
Our Hopper Pump Series is designed for superior adaptability and efficiency. With capacities up to 315m³/hr and discharge pressures reaching 480m, this range supports various applications. Its modular construction allows for easy customisation and upgrades, ensuring long-term operational flexibility.
The pump series features multiple construction variants, each optimised for specific material handling requirements. The following variations provide tailored solutions:
Standard Hopper Pump (DH/DHE Series):
- Rectangular hopper with an auger feed, suitable for up to 18% solids concentration
Heavy-Duty Hopper Pump (DHB/DHP Series):
- Wide throat hopper with a double bridge breaker, handling up to 35% solids
Industrial Hopper Pump (DHS Series):
- Oversized auger, accommodating highly viscous materials up to 28% solids
Industrial Heavy-Duty Hopper Pump (DHSB/DHS-T Series):
- Special wheel-assisted feeding system for non-flowing materials with up to 40% solids
- Patented Pin-Type Joint: Ensures reliability, easy maintenance, and resistance to high pressure (up to 12 Bar in the pump casing)
- Customisable Hopper Length: Adaptable rectangular hoppers to suit specific application needs
- Seal Systems: Multiple options, including packing seals, single/double mechanical seals, and API 682-compatible versions
- Food-Grade Certification: Available upon request for Oenological, Food, and Beverage applications
- Material Options: Cast Iron, Stainless Steel (AISI 304/316), Duplex, and Super Duplex
- Self-Priming Capability: Up to 7m, ensuring efficient fluid transfer
- Low Pulsating Flow: Axial design minimises stress and turbulence
