The light weight of the pumps and low power consumption make the unit ideal for dealing with contaminated liquids in an economic manner.
This range of pumps is suitable for stationary use. For easy removal of the pumps from deep sumps we recommend the use of our guide rail systems GR 40 which provide ease of maintenance and inspection. A controllable oil chamber and wear-resistant special mechanical seal ensure a long service life. For automatic monitoring of the oil chamber a seal leak control can be connected.
According to Ex-proof testing regulations, these pumps are provided with winding thermostats and can only be used with the equivalent control unit (see accessories).
Pump according to EN 12050 ready for connection with 10 m cable.
