The vane pump, fixed displacement division of Parker are specifically designed fir low and high circuits. It integrates different cartridges in double and triple pumps that enables high flow at low pressure, and low flow at higher pressure which is a clever way to optimize the design of a circuit. The cam ring on port plate dowel pin hole can be changed makes pump rotation easy by changing position. It features a 320 bar max pressure for T7B, 300 bar for T7AS* & T7D, 275 bar for T6C & 240 bar for T7E, Silent technology even under extreme pressure, and a wide array of displacements.
