JS-SV Submersible Sewage Pump (110V and 230V)

The JS Pumps JS-SV Series is a highly versatile range of single-phase electric submersible drainage and sewage pumps engineered for residential, commercial, and industrial dewatering applications. Designed specifically for transferring raw sewage, graywater, and effluent, these pumps excel at moving liquids containing soft, stringy suspended solids without clogging.

Utilizing a recessed vortex style impeller, the pump creates a swirling vortex inside the wide pump casing. This design allows debris, sludge, and fibrous materials to pass freely from the inlet directly to the discharge without ever coming into contact with the impeller blades, drastically reducing wear and eliminating mechanical jamming.

Key Details

• Non-Clog Vortex Impeller: The recessed layout ensures maximum solid passage and continuous flow, making it ideal for everything from domestic basement drainage to demanding commercial site sewage applications.

• Dual Float Automation Options: Available in standard manual configuration or automated variations. Choose between the heavy-duty Mac-3 trailing cable float switch for open chambers, or the compact Agma magnetic vertical tube float switch specifically designed for narrow, tight sumps where space is restricted.

• Rugged, Anti-Corrosive Construction: Built with a solid cast iron pump casing, motor top cover, and impeller plate, combined with a corrosion-resistant stainless steel motor housing and shaft.

• Dual Mechanical Seals: Protected by an internal oil-lubricated double mechanical seal assembly (Silicon Carbide vs Ceramic/Carbon) to prevent liquid ingress and maximize motor longevity under continuous load.

• Flexible Site Voltages: Stocked across standard 110V site power (yellow plug) and standard domestic/commercial 230V/240V single-phase supplies.
