Auger Feed Screw Hopper Pump

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.

Typical applications for our Auger Feed Screw Hopper Pump:

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