parker hydraulic pump rotation direction brands

Gear pumps have an input shaft that drives an inner gear or “drive” gear. When the shaft turns the drive gear, the drive gear turns the “driven” gear. As these two gears rotate, oil is pulled into the suction port, split and carried around the perimeter of the gears, and finally, combined and pushed out the discharge port.

When determining the rotation of a gear pump, one must decide on the viewing orientation. As an industry standard a pump’s rotation is determined when viewed looking at the input shaft. If your viewing orientation is at the rear of the pump, the technical rotation of the pump is opposite the visual rotation.

The suction and discharge ports are determined by the rotation of the input shaft. As with rotation, the position of each port is dependent upon the viewing orientation. Here to, the industry standard, when looking at the input shaft, is for the drive gear to be oriented above the driven gear, also known as “belly down”. In this orientation, a clockwise pump will have suction on the left and discharge on the right and vice versa. If the pump is oriented with the “belly up”, the suction and discharge ports will appear opposite.

For hydraulic pump installation or when replacing a hydraulic pump or motor, it is essential that all critical parameters are taken into account. Be sure you know the required system, pressure, RPM range, direction of rotation, shaft size and type, port size and type, and mounting information. If you have nay questions regarding replacing pumps, don’t hesitate to call our component group at 1-800-728-5168.

In many cases, OEM’s have used pumps from several different manufacturers for the same model of equipment and are, for all practical purposes, identical.

Using the above information, our trained personnel will select the proper replacement pump. Some pumps, however, have been out of production for a number of years and certain modifications may have to be made

Overhaul-, maintenance-service on pumps, motors, hydraulic systems for mobile and industrial fields. We supply spare-parts and components of the different brands as Sauer Danfoss, Poclain Hydraulics, Linde, in the main Italian cities as Modena, Brescia, Bologna, Padova, Bergamo, Verona, Torino, Milano, Firenze, Roma, Napoli, Catania, Genova.

Parker C101 / C102 fixed displacement gear pumps (“dump pumps”) offer high performance and endurance thanks to their cast iron construction. They are ideal for vocational and municipal equipment alike, and are available as a standard pump with integrated valve for raising and lower dump beds, with integral relief valve.

The C101 has two shafts and can be mounted to remote PTO’s operating in either direction of rotation. Single shaft units, C102 mount directly to the vehicle drive train. All can be connected in two- or three-line circuits to control single-acting cylinders. All units are supplied with factory-set 2000 psi relief valves.
