Description
The Oreal CK45M is a compact 230v single-phase submersible centrifugal drainage pump designed for sump pit drainage in basements, cellars, and other below-ground spaces where installation room is limited. It is the smallest model in the CK range, with a 0.25 kW motor delivering up to 150 litres per minute at a maximum head of 7.5 metres through a 1 1/4-inch (32mm) outlet.
All water-contact components are constructed from AISI304 stainless steel, covering both the pump body and impeller. Twin mechanical seals in a lubricated chamber protect the motor, and the pump can handle solids up to 10mm and liquids up to 50°C. The unit is supplied with 10 metres of power cable and a non-return flap valve as standard, which prevents backflow through the discharge line when the pump stops. All models in the range include hose tails for flexible connection.
The CK45M is a manual pump, running whenever powered. For automatic level-controlled operation, connect it via a separate float switch. Its compact footprint (273mm high x 167mm wide) makes it well suited to narrow sump pits where larger units will not fit, and the integrated non-return valve simplifies installation by removing the need to fit an external check valve on the discharge side. Maximum submersion depth is 5 metres.
