Multicut Cutting System

The unique Multicut Cutting system ensures a maximum of operational safety at outstanding delivery characteristics. Fitted with a cutter plate made of hardened stainless steel and a three-bladed knife, It disintegrates coarse additions in the wastewater with more than 62,000 cutting processes per minute before they can get in to the pump hydraulics.

Solids which cannot be transported are rejected outside of the pump by the cutting rotor as the cutting system is located upstream from the pump hydraulics. Specifically arranged grooves on the cutter plate ensure additional safety as the cutting unit is permanently cleaned automatically during the delivery.

Application

Submersible sewage pumps fitted with the Multicut cutting system are used as stationary appliances in pressurized drainage systems for discharge in sparsely populated areas or of detached house. The are suitable for pumping domestic wasterwater with the usual additions ( as specigied in German standard DIN 1986, part 3).

For pumping from ducts which are connected to the public sewer system, explosion-proof submersible pumps of the UKF series have to be used. On accout of the upstream cutting system, the pressurized 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 40⁰Celsius

Submerged motor: Continuous Operation (S1)

Emerged motor : Intermittent Operation (S3)

(e.g. 20% = 2min. operation, 8 min. break)

Pump

Vertical, Single-stage, submersible, pump housing with horizontal discharge, open impeller, Multicut cutting system – adjustable.

Bearings

Common shaft for pump and motor, grease-packed ball bearing

Seal

Silicon-carbide mechanical seal independent of the sense of rotation, oil chamber and artificial corbon mechanical seal or duplex rotary shaft seal to motor compartment, safe to run dry.

Motor

Submersible, insulation class F, type of protection IP 68, protected by winding thermostats, automatic activation by control only or – up to 3.2 kW three- phase current – by CEE plug with motor protection upon request, UFK types tested by German PTB Federal Agency, Ex designation ll 2 G Ex d llB T4

Materials

Pump and motor housing as well as impeller made of grey cast iron GG (impeller 75/2 and 76/2 made of spheroidal graphiteiron), completely covered shaft with no contact to the pumped liquid, stainless steel hardened (57 HRC) cutting system, special flexible rubber cable.

Scope of Supply

 UAK sewage pump or explosion- proof UFK submersible pump in keeping with German / European standard DIN EN 12050 with Shackle and 10 m cable, without plug, without base.

UAK / UFK 25/2 ME

As the rated output of the motor exceeds 1.4 kW, the permission of the local power supply organization has to be obtained prior to ordering and commissioning.

Soft Starting device (Only for UAK/ UFK 25/2 ME)

The soft starting device is a resistance starter with a built-in overheating protection in order to reduce the starting current to approx. 33 A. The maximum swithcning frequency is 10 / switching action per hour( at an ambient temperature of 40⁰ Celsius). This assembly group is installed in the AD 12 ExME control in the factory wen ordered. A subsequent installation is not possible.

Flushing Tube

The Flushing tube is screwed into the annular casing of the pump instead of the venting screw. It vents the pump and at the same time cleans the chamber with a jet of water. This bypass causes a loss of performance of abt. 10%
