P Series Heavy Duty Gear Pump | P20, P315, P330, P350, P51 | Truck & Forklift Hydraulic Pump

P Series High-Performance Heavy-Duty Hydraulic Gear Pumps

Product Overview: The P Series is globally recognized as the “Workhorse” of heavy-duty mobile hydraulics. This series is specifically engineered to meet the demanding requirements of commercial trucks, dumping systems, and large-scale forklifts operating in harsh environments. Our featured range covers the complete lineup: from the reliable P20 and P50 to high-pressure specs like P315, P330, P350, and high-flow models like the P51. Featuring a full cast-iron body and precision-ground gears, these pumps ensure an ultra-long service life under frequent start-stop and high-load impact conditions.

Key Technical Advantages:

• 100% Plug-and-Play Replacement: Manufactured strictly to international SAE and major OEM standards (comparable to Commercial Intertech designs). Precise codes guarantee that standard 2-bolt/4-bolt mounting flanges, drive shafts (Splined/Keyed), and port configurations are fully compatible with your existing systems.

• Reinforced Cast-Iron Construction: Utilizing high-strength ductile iron housings, these pumps offer superior mechanical properties and fatigue resistance. They resist deformation under high pulsating pressures and extreme temperatures, outperforming standard aluminum pumps.

• Efficient Axial Gap Compensation: Equipped with automated pressure-balanced side plates, maintaining volumetric efficiency above 93% during long-term service, effectively minimizing internal leakage and oil overheating.

• Flexible Tandem Configurations: Supports single, double, or even triple pump setups, allowing a single drive shaft to power multiple independent circuits, significantly saving installation space and reducing overall costs.

• Target Applications: Dump truck hoist circuits, refuse compactor systems, reach stackers, large-capacity forklifts, truck-mounted cranes, and various PTO-driven systems.
