Submersible sludge pump JS 12

Making your life easier

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).

 

Main benefits
  • 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.

Applications

Dewatering in construction

From roads and bridges to ditches and dams, construction sites are difficult places to work. Construction site managers need solid economic reasons for purchasing equipment. Our submersible dewatering pumps provide them.

Dewatering in tunneling

A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.

Mining

Whether on the surface or underground, the conditions in mines are harsh. Besides the mud, slurry, stones, and rocks, there are large volumes of water to remove in order to keep production moving. Our dewatering pumps are rugged and ready, taking on the toughest drainage and sludge removal.
