MultiCut Pumps with external adjustable cutting system0 pages
Submersible sewage pumps with cutting system MultiCutare used as non-moving appliances for backpressure pro-
tection of single buildings. They are suitable for pumpingdomestic waste waters with the usual additions (as speci-fied in DIN 1986 part 3).
For pumping from ducts that are connected to the public
sewer system ex-proof submersible pumps of the series
UFK have to be used. Due to the upstream cutting system
the pressure line manufactured in DN 40 - without cuttingsystem minimum DN 80 - can be routed parallel to the ter-rain.Operating conditions up to 40 C temperature of mate-rial to be pumpedSubmerged motor: Continuous operation (S1)
Emerged motor: Intermittant operation (S3) (eg. 35% = 3,5 min. operation, 6,5 min. pause)

nnThe MultiCut System nnThe liquid flows into the impeller through a rigid, perfora-ted cutter plate in which apertures are tapered to improve
the suction performance. The sharpened three bladed cut-
ter, rotating in front of the inlet, shears any solids present.The impeller then passes them through a counterflow system in the water plate, thence into the volute casing and out through the pump discharge.
The cutter plate rejects any material such as stones or metal that it is unable to cut. The combined cutting and
pumping system gives trouble-free,low-cost sewage dispo-
sal even with difficult ground conditions.
UFK 08/2 M The minimum flow velocity in the pressure piping must be 0,7 m/s according to EN 12056. This data is represented in the performance
curve as a limit of application. >
