Submersible drainage pump J

Long-lasting, hard-wearing, compact and convenient

The submersible drainage pump J is suitable for pumping water and dirty water mixed with light abrasives. The low weight and compact design enable convenient transport, handling and installation.

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 (J 4, J 7, J 12, J 15, J 205). For J 405 and J 604, thermal sensors in the stator windings protect the motor from overheating by means of an external control panel.
  2. J 4 and J 7 are equipped for immediate plug-in with automatic level control start as standard and offer efficient dry-running protection.
  3. An impeller in white cast iron with a full upper shroud and adjustable wear parts coated in nitrile rubber ensure high abrasion resistance. J 4 and J 7 in ductile iron.
  4. A double mechanical shaft seal in an oil bath, with primary and secondary seal surfaces in silicon carbide, extends the life of the pump. In pumps J 205 and J 405, the primary and secondary seals comprise an easy-to-replace seal cartridge. A double outer casing and good heat convection enable the pump to operate continuously at low levels – or even run dry without damaging the motor.
  5. Due to the modular design, the same parts can be used for different pumps, which lowers the overall service costs. An adjustable diffuser ensures proper clearance throughout the impeller lifetime. By removing the top cover of the pump, the electrical junction area can easily be checked.
  6. For J 205, J 405 and J 604, the conversion between high-volume and high-head hydraulics is managed with only a few parts, ensuring the right performance for the application.
