Built for Solids-Handling Applications
S Series pumps are self-priming, solids-handling pumps designed for waste-handling applications involving solids-laden liquids and slurries. Their self-priming design allows the pump to be installed above the liquid being pumped, helping keep inspection and maintenance access outside the wet well.
The large volute design supports automatic repriming in a completely open system without the need for suction or discharge check valves.
Typical applications include:
- Municipal wastewater
- Sewage handling
- Industrial wastewater
- Mining
- Steel mills
- Paper mills
- Food processing
- Power generation
- Automotive manufacturing
- Other solids-laden liquid and slurry applications
Solids-Handling Impeller Design
All Prime S Series pumps use a two-vane, semi-open solids-handling impeller. Pump-out vanes on the impeller shroud help reduce foreign-material buildup behind the impeller while reducing pressure on the seal and bearings.
Our self-priming pumps handle solids up to 3 inches in diameter depending on pump model. Pumps 4 inches and larger are designed to allow up to 3-inch spherical solids to pass through critical areas of the pump, including the circulation port.
Designed for Easier Maintenance
Because All Prime S Series pumps are self-priming, they can be mounted above the liquid being pumped. Primary wear components can be accessed through the removable clean-out cover on applicable models, allowing service to be performed without disconnecting the pump from the piping.
Accessible components include:
- Impeller
- Mechanical seal
- Wear plate
- Check-valve flapper
The rotating assembly can also be removed without disturbing the pump volute or piping. Pusher bolts assist with removal, and a spare rotating assembly can be installed to help reduce downtime.
