The submersible sludge pump JS 12 is excellent for pumping sludge and water mixed with solids. The pump has a slim design and low weight, which makes it easy to move and easy to handle. It can run without risk of overheating the motor or sludge clogging. 50 Hz: head max 12.5 meters, flow max 8.5 l/s. 60 Hz: head max 14 meters (46 feet), flow max 8.5 l/s (135 gpm).
Plug-and-pump installation without having to worry about overheating.
Clog-free pumping with free-flow vortex impeller and pump volute.
High wear resistance ensures years of cost-efficient pumping.
Slim design and low weight make the pump easy to move and handle.
Serviceability with modular design.
Non-overloading performance with two different impellers for each pump model. The small impeller allows the pump to run in low-level applications.

Benefits
Plug-and-pump installation:
Plug in without having to worry about overheating. Built-in thermal protection protects the motor from overheating.
Clog-free pumping – avoid downtime with solid-proof hydraulics:
Free-flow vortex impeller and pump volute make the sludge pump perfect for pumping solids.
Reliability and wear resistance:
One investment for years of cost-efficient pumping. Impeller and pump housing are made from wear-resistant ductile iron. Vortex hydraulics minimize load on the shaft and bearings, which ensures reliable operation and maintained efficiency. Double mechanical shaft seal in oil bath with the primary seal in silicon carbide ensures safe operation and long life.
Convenient handling – designed to make your life easier:
The motor parts in lightweight aluminum make the pump very easy to handle and install.
Serviceability:
Save time and money with easy on-site service. Modular design lowers the overall service costs. Easy access to the electrical junction box.
