Our ATEX-rated Auger Feed Screw Hopper Pump is a high-performance Progressive Cavity Pump designed for handling highly viscous and non-flowing substances with substantial solids content. Featuring a rectangular hopper and an extended auger feed screw, it ensures reliable pumping without bridge or block formation. With customisable lengths based on application requirements and a joint-protection device integrated into the auger feed screw, this pump is ideal for various industrial applications. Available in two drive configurations, it provides efficient operation in a variety of industries.

Specifications
Variations
We have 2 models available for this pump, the DHS/JHS and the DHB/JHB models, each offering the following benefits:
- DHS/JHS Models: Designed for cost-effectiveness and compactness, the DHS features a direct-drive flange coupling, while the JHS includes a shaft coupling for enhanced durability and performance
- DHB/JHB Models: Engineered for high-resistance applications, the DHB uses a direct flange coupling, whereas the JHB integrates a coupling joint and modular bearing housing for superior load absorption
- Compliance: CE-compliant and ATEX-rated for hazardous environments
- Self-Priming: Efficient self-priming capability up to 7m
- Patented Pin Joint: Enhanced durability with reduced maintenance costs through axial load and torque distribution
- Customisable Length: Rectangular hopper with adjustable auger feed screw for application-specific customisation
- Solids Handling: Capable of pumping up to 35% dry substance with high viscosity
- Drive Options: Direct-drive flange coupling (DHS/DHB) or shaft coupling with bearing housing (JHS/JHB)
- Material Variants: Available in Stainless Steel AISI 316L, 304, Duplex, and Super Duplex
- Low Pulsation Flow: Minimised pulsating flows for stable operation
- Advanced Shaft Sealing: Multiple sealing options, including mechanical seals, single/double cartridge seals, and gland packing
- Modular Design: Hydraulic parts, casing, seals, base plates, and drive shafts are customisable
- Maintenance Efficiency: Joint bushes allow worn component replacement without changing shafts and rotors
