A large hydraulic radial piston pump suitable to be driven by the turbine of a wind turbine generator has a circular cover formed from at least three cover segments. Underneath the cover segments a seal in the form of a vulcanised rubber band extends around the entire periphery of the pump. Thus, the cover can be readily removed within the difficult to access location of a wind turbine nacelle, but a reliable seal can still be formed. An air pocket outside the seal, or within the seal, facilitates pulsatile flow into the cylinders of the pump during operation. |
