Parker fixed displacement gear pumps displace oil by means of one driven gear & one idler gear meshing together. The two gears displace oil in their gear teeth notches from the suction port to pressure port. The displacement of the gear pump is a combination of the size / diameter of the gear plus the width of the unit, so fixed displacement pumps will deliver oil flow in direct relation to their swept volume and their rotational speed.

ADVANTAGES
FOUR FRAME SIZES AVAILABLE
The four frame sizes of 500 series units cover a vast range of capacities & speeds which can be matched to your particular requirement.
PRESSURE BALANCED BEARING BLOCK DESIGN
All units incorporate the use of gear shaft bearing blocks that also provide pressure balancing against the side face of the gears, so that the pressure produced by the pump actually compensates for the separating forces generated by pump pressure.
MULTIPLE VERSIONS AVAILABLE
Pumps can be coupled together to produce double or triple units. However, the largest series unit at the input stage must be capable of transmitting the total pump torque.
FOUR HOLE EUROPEAN OR SAE MOUNTS
High pressure shaft seals provide for extended seal life.

Temperature
Oil temperature should be between +30ºC & +60ºC during normal operation. Oil life is greatly reduced if temperature exceeds 60ºC. As a general rule, oil life is halved for each 8ºC temperature exceeds 60ºC.
Filtering
It is necessary to keep the level of contamination within a hydraulic system at an acceptable level to ensure trouble free operation. Filtration should always be specified at a level that protects the most sensitive item or component in the system. |
