Product Description
The Onga CSM850CF is a heavy-duty submersible sewage cutter pump designed for pumping sewage wastewater containing particles and applications where stringy materials may be present. Its semi-open cutter impeller provides a 35mm free passage, with a maximum flow of up to 1,050 L/min and maximum head of 17.5 metres.
The CSM850CF features a 1.5kW single phase motor operating on 230V, with a rated current of 10A and capacitor start/capacitor run operation. Heavy-duty construction combines a cast iron cutter impeller and pump housing with a stainless steel motor housing and shaft, while double mechanical seals operate in an oil chamber.
Designed for fully submersible operation, the CSM850CF features an 80mm (3") pressure outlet, IP68 enclosure protection, Class F insulation and a 10 metre H07RN-F power cable. The CSM850CF is the level-control version of the CSM850 range and is suited to demanding sewage and wastewater pumping installations.
