The submersible sludge pump XJS 50 is ideal for pumping sludge and water mixed with solids. Pumps with built in AquaTronic unit will always have correct direction of impeller rotation, ensuring peak performance and reduced wear. 50 Hz: head max 28 meters, flow max 25 l/s. 60 Hz: head max 31 meters (102 feet), flow max 26 l/s (413 gpm).
 
Main benefits
Plug-and-pump installation
Plug in without worrying about overheating. Built-in contactor and thermal sensors protects the motor from overheating. Pumps with a built-in AquaTronic unit will electronically adjust for incorrect phase order, ensuring correct impeller rotation.
Reliable and trouble-free operation 
Equipped with a free flow vortex impeller and a pump volute, the XJS is perfect for pumping sludge and water mixed with solids. The pump design, robust construction and premium materials ensure high wear resistance. The impeller is available in different sizes to meet your specific requirement. Min impeller diameter for duty with low water level or intermittent dry running. Max impeller diameter requires half motor or more submersed for continuous duty. (Pump can operate lying down)
Serviceability
The modular design of the pump range saves cost by ensuring maximum pump availability with a smaller spare parts inventory.The condition of a pump with a built-in AquaTronic unit can rapidly be checked without disassembly, using its service software.
Saves energy and the environment
The high-efficiency motor and hydraulics are combined with low friction bearings to reduce power losses. You achieve low total energy costs and minimize your carbon footprint. Environmentally safe white oil is used in the oil casing for easy inspection of seal conditions.
