Oase ClearDrain Drainage pumps are designed for pumping unwanted water from cellars, basements etc, or for use in emergency flood situations and for flood prevention. They can drain water down to very low levels - down to 1mm depth in fact (also known as puddle sucking or shallow-priming), thanks to a special base adapter with bayonet fitting.
Automatic sensors are used to switch the pump on once water reaches a particular level (depth). When the water is drained to below the set sensor level the pump will switch off again - or you can drain all the way down to as little as 1mm depth. The distinctive design features a robust stainless steel housing and the pump's compact configuration means that they can be submersed into a very small sump area (minimum sump size of 20 x 20cm). The position of the outlet being at the top of the pump also means that water flows through the motor when in use, providing effective cooling and therefore leading to longer service life. Capable of pumping clear to slightly murky water, they have a solids handling capability of up to 5mm particle size.
