Capacity : 175 gpm (662 lpm)
Head : 33 ft (10.1 m)
Single and Double Seal
The WHR Series Pumps are designed for use in light Commercial and Residential Raw Sewage Applications. WHR Pumps will Pass a full 2-inch sphere. The recessed vortex impeller provides an unobstructed passage in the volute case which allows these pumps to handle stringy, trashy solids without plugging the impeller. The vortex impeller also greatly extends the pumps bearing life. Available in double seal configuration for extended motor life.
Advantages By Design
Durable Motor
- Oil-filled for cooler operation and constant bearing lubrication.
- Single phase PSC motors have no starting switch to fail.
- Recessed impeller reduces radial bearing loads, increases bearing life.
Non Clog Operation
- Recessed vortex impeller passes 2" solids.
- Impeller operates completely out of volute passage.
- Passes stringy trash and other solids which conventional semi-open impellers can not.
Available With Automatic Piggy-Back Switch for Maintenance-Free Operation
- Piggy-backed mechanical float switch allows pump to operate automatically or can be unplugged for manual operation.
