SEEPEX open hopper pumps have a feed hopper and an auger feed screw to positively feed products into the pumping elements. The pitch and diameter of the auger can be adjusted according to operating conditions for optimal product feed. The feed hopper can be designed to suit diverse application conditions. They are suitable for many applications in sludge dewatering and treatment and wastewater treatment.

When coupled with a liquid feed pump, the open hopper pumps from product group T can be used to backmix dewatered sludge cake with liquid to produce the correct ds% for onward processing.  Control systems from SEEPEX complete the backmixing system

SEEPEX open hopper pumps handle viscous to semi-solid products with low or no flowability. They come in 9 ranges with multiple variations within each range.
