Parker 0301562 Hydraulic Gear Pump 20.9 Gpm Sae B

Product Description

The PARKER 0301562 is a hydraulic gear pump designed for mobile and industrial hydraulic systems requiring reliable, high-pressure fluid delivery. Rated at 20.9 GPM at 2,500 RPM, it delivers 17.46 GPM at 1,800 RPM and 34.92 GPM at 3,600 RPM, covering a wide range of operating speeds. Maximum working pressure is 2,250 psi. The pump features a 7/8-inch shaft diameter, an SAE B mount configuration, and a 1-5/8-12 UNF-2B SAE inlet port size. Displacement is 2.24 cubic inches per revolution. At 15 pounds, this unit is a compact, field-serviceable component installed by hydraulic system technicians and equipment mechanics on mobile machinery, power units, and industrial equipment.

The PARKER 0301562 is suited for applications in construction equipment, agricultural machinery, industrial power units, and other systems where a fixed-displacement gear pump with SAE B mounting is required. The SAE B two-bolt mount pattern and 7/8-inch keyed shaft interface are common configurations across a broad range of hydraulic circuits, making this pump appropriate for both OEM installations and field replacements on equipment with matching port and mount specifications.

Key Features

• 20.9 GPM flow rate at 2,500 RPM with consistent output across a range of drive speeds
• 2,250 psi maximum working pressure for demanding hydraulic circuits
• 2.24 cubic inches per revolution fixed displacement for predictable system performance
• SAE B two-bolt mount pattern for broad equipment compatibility
• 1-5/8-12 UNF-2B SAE inlet and port sizing for standard hydraulic plumbing
• 7/8-inch shaft diameter for direct coupling to PTO, engine, or gearbox drive

Compatibility

Designed as an OEM-style replacement or direct-fit gear pump for hydraulic systems specifying an SAE B mount, 7/8-inch shaft, 2.24 cubic inch displacement, and 1-5/8-12 UNF-2B SAE port configuration.

Installation Notes

Installation and service should be performed by a qualified hydraulic system technician or equipment mechanic. Before removing or installing this pump, relieve all hydraulic system pressure, shut down the prime mover, and allow residual pressure to dissipate fully. Ensure inlet and outlet port connections are clean and free of contamination prior to assembly, as gear pumps are sensitive to particulate ingress. Verify shaft alignment and coupling engagement before applying load, and follow equipment manufacturer torque specifications for all fasteners and fittings.
