SK Series Sewage
PDF datasheet mirror for SK Series Sewage (JS Pump). Verify with OEM before design.
Summary
Product identification
The SK-SERIES Sewage Shredder Pump is designed for handling sewage and industrial wastewater, agricultural waste, water treatment sludge removal, and hospital waste or other corrosive liquids.
Key features include:
- Shredding Mechanism: Incorporates a tungsten carbide cutting tip on a single vane impeller, which runs against a scored diffuser plate, shredding solids to a size slightly larger than a grinder pump.
- Impeller Design: Non-clog, single vane impellers engineered for high volume and lift performance.
- Motor Protection: Overload protection against overheating and high amperage.
- Sealing: Dual mechanical seals in a separate oil-chamber with an oil-seal-ring on the outside.
- Motor Type: Dry motor.
- Factory Tested: Each pump is factory tested for performance and safety.
Materials
- Motor Casing, Rotor Shaft, Hardware: 304 stainless steel.
- Other Exposed Parts: Cast iron.
- Cutter: FCD400 with Tungsten Carbide (WC).
- Grinding Plate: FCD700 (ISO-PIO).
Available Options
- Slide rail systems.
- Float switch.
- All 316 cast stainless steel construction.
