20100290937 | FLUID PUMP ASSEMBLY - A fluid pump assembly includes a double acting fluid cylinder with a housing, a piston reciprocally disposed within the housing, and a piston rod carrying the piston and extending from the housing. The piston rod has an end. A pump includes a pump body, a pressure loaded seal and a wiper seal. The pump body has a fluid inlet, a pump chamber and a rod port. The inlet is configured for receiving a fluid to be pumped and is in fluid communication with the pump chamber. The piston rod extends through the rod port and the end is positioned within the pump chamber. The pressure loaded seal is positioned within the rod port around the piston rod and has a pressure loaded end face toward the pump chamber. The wiper seal is positioned within the rod port around the piston rod on a side of the pressure loaded seal opposite from the pump chamber. The pump body further has a scavenging groove in an area between the pressure loaded seal and the wiper seal. The scavenging groove is in fluid communication with the inlet, whereby any fluid which leaks past the pressure loaded seal is returned to the inlet. | 11-18-2010 |
