Parker Hydraulic Pump Identification

Parker hydraulic pump and motor identification. When bidding on surplus Parker hydraulic motors it’s often impossible to tell which model you’ve got without opening the unit up. Sometimes it’s a toss up between two models or similar looking units. I’ve compiled pictures and numerical data to help you identify the appropriate models.

Parker Hydraulic Pump Interpretation Of Nameplate Information

Model number: The model number identifies the specific pump model. This information is used to order replacement parts or service kits.

Displacement: The displacement of a hydraulic pump is determined by its bore and stroke, which are found on the nameplate. Generally speaking, larger bore pumps will provide higher flow rates at lower pressures. Smaller bore pumps will provide higher pressures at lower flow rates.

Inlet pressure: Inlet pressure is determined by the amount of pressure that can be applied to the inlet side of the cylinder. It can be measured using a manometer or specialized instrumentation and equipment.

Maximum pressure: Maximum pressure is determined by how much pressure can be applied to the outlet side of a piston-type pump or through internal leakage past seals on pistonless pumps (for example, gear pumps). It can be measured using specialized instrumentation and equipment.

Parker 600 Series Hydraulic Pump Identification

The Parker 600 Series hydraulic pump is a compact, heavy-duty, single-stage pump that is well suited for use in a wide variety of industrial and mobile applications. The 600 Series pump is available in three different sizes: the 602 (1/2 HP), 604 (3/4 HP), and 606 (1 HP). These pumps provide flow rates up to 7 GPM at pressures up to 2,000 PSI.

The Parker 600 Series hydraulic pump features a cast iron volute housing with double mechanical seals. It has a two-stage piston with a self-lubricating bronze bushing, an integral cooling system and one piece cast iron construction. The Parker 600 Series pump also has an automatic bypass valve that protects against excessive pressure surges resulting from pump overloads or water hammer conditions.

The Parker 600 Series hydraulic pump comes standard with an anti-vibration mounting kit which helps reduce noise levels when used in mobile applications such as construction equipment or other vehicles where vibration can cause noise problems.
