WC / Submersible wastewater pump with cutter
WC combines a submersible sewage pump with a cutter impeller and ring. The cutting assembly reduces fibrous material before it enters the discharge path. The catalogue covers two-pole and four-pole constructions for wastewater and sewage duties where a standard drainage impeller may be more prone to obstruction.
Range bounds are a catalogue overview. Check flow and head together on the selected model curve; maximum values are not a guaranteed combined duty point.
Series catalogue ↗Series overview
The WC series uses a semi-open vortex impeller with a cutter ring at the intake. Both cutting components are specified in high-chromium stainless steel, while tandem mechanical seals and an epoxy-sealed cable entry protect the motor assembly. The catalogue distinguishes two-pole and four-pole versions and gives separate performance curves and construction information.
WC is intended for submerged operation in wastewater and sewage containing material that the cutter can break down. Selection should follow the required duty point and the actual nature of the solids. Cutter construction does not replace checking that the liquid and installation conditions fall within the catalogue limits.
High-chromium stainless steel 420 cutter impeller and cutter ring; double mechanical seals with silicon-carbide faces.
Wastewater and sewage at 0–40 °C. The IP68 motor is intended for continuous submerged operation. Built-in auto-cut thermal protection is specified for single-phase models.
The vortex semi-open impeller and cutter ring cut material in the wastewater before discharge. Check the actual waste stream when specifying the pump.
The catalogue specifies a built-in auto-cut thermal protector on single-phase models. Confirm the protection arrangement for the selected electrical version.

Choose the pump by the liquid, required flow and total head, electrical supply and installation conditions.
FC is a light sewage range with a closed single-channel impeller. Its catalogue covers clean to slightly dirty water and lists the solids passage for each model. Stainless steel construction and single-phase or three-phase versions make it a distinct series from the larger FC stainless steel wastewater catalogue.

FC Inox is the separate FC wastewater catalogue with a double-channel impeller and stainless steel wetted parts. Its stated applications span water exchange, drainage and filtration in agricultural and landscape settings. The model range and hydraulic data differ from the light FC catalogue and should be read independently.

The KTZ-LH catalogue combines two submersible drainage ranges with cast-iron construction and high-chrome-alloy impellers. KTZ has a semi-open impeller and ductile-iron wear plate; LH has a separately specified construction for deep-well pre-dewatering and high-head drainage. Both ranges list civil engineering, mining and treatment-plant applications.
