Centrifugal submersible sewage pumps fitted with the MultiCut cutting system are used as stationary appliances for backpressure protection of detached houses. They are suitable for pumping domestic wastewater with the usual additions (as specified in German standard DIN 1986, Part 3).
For pumping from ducts which are connected to the public sewer system, explosion-proof submersible pumps of have to be used. On account of the upstream cutting system, the pressurised line as from DN 32 - as from DN 80 minimum without cutting system - may be routed parallel to the terrain.
Operating conditions up to a temperature of the material to be transported of 40° Celsius Submerged motor: Continuous operation (S1) Emerged motor: Intermittent operation (S3) (e.g. 35% = 3.5 min. operation, 6.5 min. break)
