Parker 0301567 Hydraulic Gear Pump 26.1 Gpm Sae B

Product Description

The PARKER 0301567 is a hydraulic gear pump designed for high-demand fluid power applications in mobile and industrial hydraulic systems. It delivers 26.1 GPM at 2,000 RPM with a maximum working pressure of 2,000 psi, making it a capable unit for powering hydraulic circuits in equipment requiring consistent, high-volume flow. The pump features a 7/8-inch shaft diameter and mounts to an SAE B mount configuration. Inlet porting uses a 1-5/8-12 UNF-2B SAE connection. At 1,800 RPM, output is 22.86 GPM; at 3,600 RPM, output reaches 45.72 GPM. Displacement is 2.93 cubic inches per revolution. Licensed hydraulic technicians and heavy equipment mechanics are the primary installers.

This gear pump is suited for use in mobile equipment, construction machinery, agricultural equipment, and stationary industrial hydraulic power units. The SAE B mount and SAE port sizing make it compatible with standard hydraulic system architectures where a bolt-on replacement or new installation requires a fixed-displacement gear pump. The 1-5/8-12 SAE port size on both the inlet and outlet accommodates standard SAE hydraulic fittings common in these applications. The pump is appropriate for use in both open-center and pressure-compensated circuits depending on downstream valve configuration.

Key Features

• 26.1 GPM output at 2,000 RPM for high-volume hydraulic circuit demand
• 2,000 psi maximum working pressure for heavy-duty system compatibility
• 2.93 cubic inches per revolution displacement for predictable, consistent flow
• SAE B mount configuration for direct bolt-on installation to standard pump pads
• 1-5/8-12 UNF-2B SAE inlet and 1-5/8-12 SAE port sizing for standard fitting compatibility
• 7/8-inch shaft diameter matches common PTO and drive adapter configurations

Compatibility

Designed as an OEM-style fixed-displacement gear pump for hydraulic systems using SAE B mount configurations and 1-5/8-12 SAE port connections. Verify system flow rate, pressure rating, shaft interface, and mount type before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power systems. Depressurize and isolate the hydraulic circuit fully before removing any existing pump or fittings. Ensure the drive shaft alignment is within manufacturer tolerances to prevent premature seal or bearing wear. Flush the hydraulic system and verify fluid type and cleanliness level before commissioning the replacement pump.
