The submersible sludge pump JS 15 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 engine or sludge clogging. 50 Hz: head max 15.5 meters, flow max 10 l/s. 60 Hz: head max 18.5 meters (61 feet), flow max 11 l/s (174 gpm).
 Main benefits
 Easy start – plug in without worrying about overheating
 Built-in contactor connected to the thermal sensors 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 hydraulic minimizes load on shaft and bearings, which ensures reliable operation and maintained efficiency. Double mechanical shaft seal in oil bath with primary seal in silicon carbide ensures safe operation and long life.
 Convenient handling – designed to make your life easier
 Having engine parts in lightweight aluminum makes the pump very easy to handle and install.
 Serviceability – save time and money with easy and on-site service
 Modular design lowers overall service costs. Easy access to the electrical junction box.
