Submersible sludge pump JS

Take control of your sludge pumping

Submersible sludge pump JS is excellent for pumping dirty water and water mixed with solids. The pump has a slim design and low weight, which makes it easy to move and easy to handle.

MAIN BENEFITS

MAIN APPLICATIONS

  1. A built-in contactor connected to the thermal sensors in the stator windings protects the motor from overheating and features an automatic restart function.
  2. JS 4, JS 7 and JS 8 are equipped for immediate plug-in with automatic level control start as standard and offer a dry running protection.
  3. A free-flow vortex impeller and pump volute make the pump ideal for pumping solids. The impeller is available in different sizes to meet specific requirements.
  4. Both the impeller and volute are made from heavy-duty ductile iron for maximum durability. Double mechanical shaft seals in an oil bath, with primary and secondary seal surfaces in silicon carbide, extend the life of the pump.
  5. The top cover and motor housing are made of lightweight aluminum, which creates a pump that is very easy to handle and install.
  6. Due to the modular design, the same parts can be used for different pumps, which lowers the overall service costs. External inspection ports for the oil and motor chambers enable quick and easy evaluation of the shaft seal during service. By removing the top cover of the pump, the electrical junction area can easily be checked.
