Description
The Oreal CK45M stainless steel sump pump (code 9000-2130) is a 230v submersible centrifugal sump pump with AISI304 stainless steel pump body and impeller, for clean, dirty and black water. It pumps up to 150 litres per minute and reaches a maximum head of 7.5 metres from a 0.25 kW motor on 230v single-phase, the standard UK mains supply. It is the smallest pump in the range and the only one with a non-return flap valve built in, sized for tight basement and cellar sumps.
It is a manual pump, running whenever it has power. For automatic level control, run it through a separate float switch. The Oreal CK55M is the next size up, 216 l/min to 11 m.
Every water-contact part, including the pump body and impeller, is AISI304 stainless steel, so the pump resists corrosion in sumps that stay wet for long periods. Twin mechanical seals in a lubricated chamber protect the motor. The pump passes solids up to 10 mm, handles liquids up to 50°C, can be submerged to 5 metres and comes with 10 metres of power cable and a hose tail.
