The EXTREMA CUT 300/18 CX chopper pump is perfect for pumping liquids with high solids content. The Reamer Grinding high-performance cutting unit shreds solids easily. The cutter is made of high quality stainless steel (AISI 440) with a Rockwell hardness of 55 (HRC). Featuring a large 2″ vertical outlet, stainless steel motor housing and extremely robust cast iron hydraulic unit, this pump is equipped for the toughest operations in construction- and dirty water trenches, and can transport liquids with dirt particles up to 50 mm without a problem. In contrast to conventional submersible wastewater pumps, this pump is also suitable for liquids with higher temperatures in continuous operation up to 50 °C, and even up to 90 °C for short periods (approx. 4 min). It is also equipped with a lockable float switch for automatic and manual operation.
Static head/flow rate:
14 m – 8.000 l/h
10 m – 13.050 l/h
6 m – 15.960 l/h
2 m – 17.600 l/h
A pump’s flow rate is mainly dependent on its static head. The above table gives the capacity of the EXTREMA CUT 300/18 CX submersible dirty water pump at different static heads. For example, if water is pumped from a depth of 2 metres, the expected delivery rate for this pump is 17.600 litres per hour.
