Double Shaft Hopper Pump

DHB, JHB Series

Auger Feed

Highly Viscous Media

Our Double Shaft Hopper Pump features a hopper and auger feed screw for efficient pumping of highly viscous, non-flowing materials with high solids content. Available in ATEX-rated double-shaft or bridge breaker configurations, it uses an enhanced auger feed screw to improve hydraulic efficiency. Designed for difficult-to-handle substances with up to 35% dry solids content, the pump can be customised in length to suit specific applications.

Typical applications for our Double Shaft Hopper Pump:

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

Key Features

Features and Benefits of a Double Shaft Hopper Pump:

Compliance: CE-compliant and ATEX-rated.
Self-Priming: The hydraulic parts enable excellent self-priming (up to 7m).
Pin Joint: Allows subdivision of axial loads and torque, for cost-effective replacement.
Materials: Cast Iron & Stainless Steel. Auger feed screw can be AISI 304/316 on request.
Low Pulsating Flow: Tensional stress and pulsating flow are minimised.
Shaft Sealing: Various sealing systems are available.
Base Plates: Available in Carbon Steel or Stainless Steel.
Joint Protection: Ensures the integrity, especially when pumping abrasive substances or those with solids.
Modularity: These pumps offer modularity and can be customised.

Variations

DHB

Direct-drive flange coupling provides a cost-effective, compact design, with hydraulic components supported by the drive unit. The system is durability-tested to perform reliably under heavy loads.

JHB

With flexible coupling, it delivers superior performance and durability. Bearings absorb stresses, providing excellent resistance, whilst the modular housing design offers installation flexibility.
