The Davey D42A/B20 is a high-pressure submersible sump pump designed for drainage, water transfer and non-potable rainwater applications. Its multistage centrifugal design provides higher pressure performance than a standard drainage pump, making it suitable for applications where water needs to be transferred to a greater height.

The pump features stainless steel components, a double mechanical seal and automatic thermal overload protection for reliable operation in demanding drainage applications.
