Product Overview Pressure to 0 PSI Automatic Reversing Positive Displacement Automatic Pressure Relief Designed for OEM built in Applications Four Series, Multiple Sizes - 0.13 to 135 GPM Configuration 1: Tab/Pin in Torque Ring Mates with Slot in Machinery Drive Shaft Configuration 2: Slot in Torque Ring Mates with Tab/Pin in Machinery Drive Shaft Pump Consists of Rotor/Torque Rings, Assembly, Idler, Carrier Assembly, and Floating Plate Options Cover - See Pages () Springs and Transfer Bushings - See Pages () TR Series Typical Layout OPTIONAL COVER SHOWN (INTERNAL OR EXTERNAL PORTS AVAILABLE) CARRIER ASSEMBLY IDLER FLOATING PLATE OPTIONAL TRANSFER BUSHING ROTOR/TORQUE RING ASSEMBLY SHOWN WITH SLOT FOR PIN. (OPTIONAL TORQUE RINGS AVAILABLE WITH WELDED PIN FOR DRIVING.) OPTIONAL SPRING (VARIOUS SPRINGS ARE AVILABLE FOR SETTING VARIOUS RELIEVING PRESSURES.) General Pump Operation In operation all parts of the pump assembly rotate with the drive shaft except the idler gear, idler carrier, and cover. Driven by the rotor assembly, the idler gear turns on the idler pin, and because it has one less tooth than the rotor gear with which it meshes, pumping action is created. The idler carrier is positioned against the cover. When the drive shaft changes rotation, the idler carrier rotates 1 degrees, maintaining the same direction of flow. The relief valve spring (or pre-compressed spring assembly) keeps all parts of the pumping unit together at less than relief valve settings. When relief pressure is reached the spring compresses and pump clearances increase, allowing oil to bypass between the idler carrier and the gear set, and this oil is relieved externally of the pump.
