Applications
Designed for pumping abrasive or frothy slurries. Handles varying or intermittent flows. Typical installations include virtually all slurry pumping applications in mineral processing pilot plants and small commercial installations.

 

Improvements
Deep Bowl provides 250% of previous shallow bowl volume.

 

Plus Factors
Increased surge capacity; increased gpm pumping capacity; increased discharge pumping head and pumping efficiency due to increased runner intake head; greater ability to break down and handle froth; ability to either feed into top of bowl or at alternate side low level minimum entrance.

 

Plus Maintenance Factor
Deep Bowl pump is provided with 2" overflow riser on one side of the pump. This riser is designed to overflow slurry and/or froth at level that will protect the pump's lower seals and bearings from immersion. The riser can be rotated to the proper height to suit specific installations. Riser is provided with pipe-to-hose fitting for connection drain hose if desired. Rotating slinges and double grease seal arrangement are still provided as added protection.
