Concentric/Haldex GC Series Gear Pump: 0.097 CID, 0.75 GPM @ 1800 RPM and 1 GPM @ 3600 RPM, 4000 Max RPM, 3000 PSI with SAE #6 Port Size, 4-Bolt (1.78’’ Dia Pilot) Mounting, Dual Rotation, 250056

Description

Product Overview

The Concentric Haldex GC Series gear pump, model 250056, is engineered for demanding industrial applications where precision flow and high pressure are essential. With a displacement of 0.097 cubic inches per revolution, the pump can move up to 1 GPM at 3600 RPM while maintaining a maximum operating pressure of 3000 PSI. Its dual‑rotation capability allows the pump to run in either direction, providing flexibility for system designers. The unit features SAE #6 side inlet and outlet ports, a 4‑bolt (1.78‑inch pilot) mounting configuration, and a 1/2‑inch straight‑keyed shaft that extends 1.5 inches for secure coupling. Constructed from hardened steel, the internal gears are heat‑treated for wear resistance, and the housing is machined to tight tolerances to minimize internal leakage. The pump is rated for a maximum speed of 4000 RPM, delivering consistent performance even under rapid cycling conditions. Its compact size and 5‑pound weight make it suitable for a variety of hydraulic assemblies, from mobile equipment to stationary machinery.

Usage

Designed for use in industrial hydraulics, pneumatic systems, and plumbing applications, this gear pump excels in environments that demand reliable fluid delivery at high pressure. It is ideal for powering hydraulic presses, material handling equipment, and precision machining tools where steady flow rates are critical. The dual‑rotation feature enables operators to reverse flow direction without needing additional components, simplifying system design and reducing overall cost. The robust 4‑bolt mounting ensures the pump can be securely attached to a variety of base plates and frames, making installation straightforward even in confined spaces. Its ability to operate up to 4000 RPM allows it to meet the rapid response requirements of modern automated production lines. Whether used in a mobile construction vehicle or a fixed‑position manufacturing cell, the pump delivers consistent performance, reducing downtime and maintenance intervals.
