Screw pumps with a Wide Loading Hopper

Screw pumps with a Wide Loading Hopper

Design of the  WМ  series pumps allows them to be used for many different jobs. Standard design includes an enlarged rectangular hopper with a screw conveyor that propels the pumped product into the pump head.

There are modifications in which the pump inlet funnel is equipped with a large auger, an integrated crust breaker, or both. In most cases, pumps are supplied in a close-coupled design (direct connection of the pump to the electric motor) or with a free shaft outlet (without an electric motor).

WM Series has been designed to handle highly viscous materials such as silt, sludge, thick non-runny pastes and dewatered sludge with viscosities of up to 1,000,000 cps.

Features of WM Series Hopper Pumps

• Provides an efficient way to handle high solids sludge.
• Various design configurations depending on the application; when using built-in bridge breakers or large feed augers, solids up to 15% can be processed.
• Facilitates maintenance due to simple design and use of a plug in the shaft. Designed to operate at relatively slow speeds to minimize damage to shear sensitive products.
• Can be supplied with a chopper mounted horizontally on a hopper to assist in solids reduction prior to pumping. The pumps can be supplied in accordance with ATEX directive 94/9/EC.
