Industrial Hopper Pump

Our Industrial Hopper Pump, featuring an Auger Feed Screw, is designed for pumping viscous and non-flowing substances with high solids content, making them ideal for use in various industrial applications. These pumps feature rectangular hoppers and auger feeds and are customisable in length based on your application requirements. These ATEX-rated Progressive Cavity Pumps are suitable for substances with poor flowability, handling up to 18% dry substance without forming bridges.

Typical applications for our Industrial Hopper Pump:

  • Sewage Sludge
  • Water Treatment
  • Industrial Sludge
  • Detergents & Chemicals
  • Papermaking Products
  • Agriculture
  • Petrochemical By-Products
  • Maritime

We have 2 models available for this pump, the DH and JH, each offering the following benefits:

  • DH: Drive directly coupled to the pump via a flange, offering a cost-effective and compact solution. The hydraulic stresses are supported by the drive itself. Each drive undergoes stringent duration tests with heavy loads
  • JH: Drive connected to the shaft inlet via a coupling joint, providing optimal performance and durability. Bearings in the housing absorb all stresses generated by the pump. The modular bearing housing can be installed after a pump with the JX series block housing
Features & Benefits
  • Compliance: CE-compliant and ATEX-rated for use in hazardous environments
  • Self-Priming: The hydraulic parts of these Progressive Cavity Pumps enable excellent self-priming (up to 7m)
  • Patented Pin Joint: The pin-type joint, the ‘heart’ of the single screw pump, offers superior reliability and reduced maintenance costs. Its compact design enables the subdivision of axial loads and torque in different elements, while replacement of worn parts remains cost-effective, thanks to the wear-resistant bushes in critical zones. Additionally, the pin can be hydraulically balanced to withstand pressures up to 12 Bar in the pump casing
  • Base Plates: Thick and robust base plates, available in Carbon Steel or Stainless Steel, ensure strength and stability. Options include trolley-mounted versions, anti-vibration housing, or skids, meeting API676 standards
  • Materials: Product-contact components are available in various materials. From Cast Iron to Stainless Steel (AISI 316L and 304), Duplex, and Super Duplex. In Cast Iron executions, the rotating parts are manufactured in Stainless Steel AISI 420, or AISI 316l/304 on request
  • Low Pulsating Flows: Very low tensional stress and pulsating flows with minimised centrifugal effects due to low operating speeds and predominantly axial pump development
  • Shaft Sealing: Multiple sealing systems can be installed, including mechanical seals, single outer mechanical seals, double mechanical seals, and packing seals, all of which are interchangeable on the standard pump, allowing for versatility in different operating conditions
  • Modularity: This range follows a modular concept in every characteristic, including hydraulic parts, casing, seals, base plates, housing, and drive shafts. Each component can be manufactured in various executions without altering the existing structure
  • Motorisations: All drives installed on this range undergo extensive testing for reliable performance. Both electric and hydraulic motors are available, with reducers and variators featuring specific characteristics in terms of strength, bearing size, and gear quality
  • Efficiency: Greater operational efficiency thanks to optimal volumetric yield even at high pressures and minimal consumption
  • Maintenance: The joint bushes facilitate replacement without the need to replace shafts and rotors, resulting in significantly reduced maintenance costs that ensure the pumps full life cycle cost remains highly competitive
