The Sunfab fixed displacement two-stage pump is ideal for vehicles that require two different discharge outlets.
Sweden SUNFAB Corporation In various hydraulic equipment for vehicles, large-capacity single discharge pumps are used. As a result, there are instances where the speed required is too slow, leading to rapid heat generation. Sunfab's two-stage pumps provide the most optimized solution both technically and economically. Sunfab's two-stage pumps can be used with two ports for equal flow discharge and one port for low flow and one port for high flow. The latter can create three types of flow: low flow, high flow, and a combination of both. When different pressure levels are required, combinations can be made based on flow and pressure to maximize the allowable power take-off capacity.

basic information
The SCPD DIN has two types of displacement volumes and a maximum operating pressure of 40 MPa. It can be directly mounted with a gearbox that allows for power take-off. It supports both left (L) and right (R) rotation, and the rotational speed is optimized. ● High self-priming speed ● Maintains low noise levels at maximum speed ● Long lifespan due to the selection of high-quality materials such as bearings and seals ● The O-ring of the double shaft seal eliminates oil leakage from the power take-off and pump, not just at the contact surface.
