Hydro-Gear PR Series Commercial Pump
The PR2JBCGY1EXXXX is part of Hydro-Gear's professional P Series commercial piston pump family.
Hydrostatic piston pumps convert mechanical engine power into hydraulic flow, allowing the machine's hydraulic drive system to control wheel or equipment movement.
The PR Series is designed to provide:
-
Smooth hydraulic operation
-
Efficient power transfer
-
Variable speed control
-
Forward and reverse operation
-
Reliable commercial performance
-
Controlled machine maneuverability
This makes the PR Series well suited for demanding commercial turf and outdoor power equipment applications.
16 cc Variable-Displacement Design
Hydro-Gear specifies the PR Series at 16 cc per revolution, or approximately 0.97 cubic inches per revolution.
The variable-displacement design allows hydraulic output to change according to control input.
This provides the precise speed and directional control needed in hydrostatic equipment such as commercial zero-turn mower drive systems.
Commercial Hydraulic Performance
Hydro-Gear rates the PR Series for demanding operating conditions.
Published PR Series system-pressure specifications include:
-
Continuous: Up to 1,250 PSI
-
Intermittent: Up to 2,500 PSI
-
Peak: Up to 3,750 PSI
The pump is engineered to handle the varying hydraulic demands produced during normal acceleration, turning, maneuvering, and commercial equipment operation.
Smooth Forward & Reverse Control
The Hydro-Gear PR Series provides an infinitely variable operating range from zero to full displacement in both:
-
Forward
-
Reverse
This variable hydrostatic control allows commercial equipment to change speed and direction smoothly without a conventional multi-speed mechanical transmission.
On compatible zero-turn mower systems, this contributes to:
-
Precise steering response
-
Smooth acceleration
-
Controlled reversing
-
Tight maneuverability
-
Consistent drive performance
Designed for Commercial Hydrostatic Systems
The PR-2JBC-GY1E-XXXX Hydraulic Pump is designed for compatible commercial equipment using this exact Hydro-Gear pump configuration.
Possible equipment applications can include:
-
Commercial zero-turn mowers
-
Professional turf equipment
-
Commercial mowing equipment
-
Hydraulic drive systems
-
Other compatible Hydro-Gear-equipped machinery
Hydro-Gear PR Series pumps are available in many different configurations. Do not order based only on “PR Series.”
The complete model number must match the original pump.
Verify the Complete Hydro-Gear Model Number
For correct replacement, compare the identification label on your existing hydraulic pump.
The required number for this product is:
PR-2JBC-GY1E-XXXX
It may also be written as:
-
PR2JBCGY1EXXXX
-
PR 2JBC GY1E XXXX
-
PR-2JBC-GY1E-XXXX
Hydro-Gear produces many pumps that look similar externally but can have different:
-
Input shafts
-
Control arms
-
Port configurations
-
Charge-pump configurations
-
Rotation requirements
-
Mounting arrangements
-
Internal specifications
Always match the complete Hydro-Gear model number before ordering.
Ideal for Hydrostatic Drive Repair
The PR2JBCGY1EXXXX hydraulic pump may be appropriate when the original pump has experienced confirmed internal failure or excessive wear.
Possible symptoms associated with hydraulic-drive problems can include:
-
Weak drive performance
-
Loss of hydraulic power
-
Slow forward or reverse movement
-
Uneven drive response
-
Excessive hydraulic noise
-
Loss of performance when hot
-
Hydraulic leakage
-
Difficulty maintaining consistent machine speed
However, these symptoms can also be caused by hydraulic motors, belts, filters, oil level, hoses, control linkage, air in the system, or other components.
Proper hydraulic-system diagnosis is recommended before replacing the pump.
Genuine Hydro-Gear OEM Replacement
The PR-2JBC-GY1E-XXXX is a genuine Hydro-Gear replacement pump.
Using the correct OEM hydraulic pump helps maintain:
-
Original system configuration
-
Proper hydraulic displacement
-
Correct shaft configuration
-
Correct control characteristics
-
Proper mounting geometry
-
Designed hydraulic performance
Because hydrostatic systems depend on precisely matched components, using the correct pump configuration is especially important.
Installation & Hydraulic System Service
Hydraulic pump replacement is a major service procedure and should be performed by an experienced technician.
Before installation:
-
Park and secure the equipment on a flat surface.
-
Turn off the engine and remove the ignition key.
-
Allow the hydraulic system to cool.
-
Clean the pump and surrounding hydraulic area thoroughly before disassembly.
-
Confirm the original pump model is PR-2JBC-GY1E-XXXX.
-
Inspect hydraulic hoses, fittings, filters, belts, pulleys, and related components.
-
Install the replacement pump according to the equipment and Hydro-Gear service procedures.
-
Fill the hydraulic system with the manufacturer-specified fluid.
-
Purge air from the hydrostatic system using the proper procedure.
-
Inspect for leaks and verify correct forward and reverse operation before returning the equipment to service.
Hydraulic systems can operate under high pressure. Always follow Hydro-Gear and equipment-manufacturer service and safety procedures.
