Buying Guide
Key considerations when choosing a hydraulic pump for a gas engine system include required flow rate, working pressure, mounting compatibility, and overall build quality. For fast cycle times on larger tasks, pumps in the 16–22 GPM range with 3600 RPM and high PSI (around 4000 PSI) are advantageous, especially in demanding outdoor jobs. Lower-pressure options (around 3000 PSI) may suit lighter workloads or smaller engines where space and weight are at a premium.
Mounting and inlet/outlet compatibility are critical. Many units use 1” or 1-1/4” inlets and 1/2” or 3/4” NPT outlets; ensure your engine’s hydraulic reservoir, hoses, and fittings align. Aluminum housings provide corrosion resistance and lighter weight, aiding portability in field applications. A complete kit with a directional control valve, installation base, and hardware simplifies installation and reduces compatibility concerns.
Durability and maintenance are also important. Look for units with robust end plates and corrosion-resistant seals, especially for outdoor use. Some pumps include additional components like key hecks and shaft details to support long service life in high-pressure environments. Finally, verify that the pump’s operating speed and torque align with your engine’s capabilities to avoid under- or over-driving hydraulic components.
