GPC4 Series High Pressure Gear Pump | GPC4-40, GPC4-80-40, GPC4-20-20 | Cast Iron Hydraulic Pump

GPC4 Series High-Performance Heavy-Duty Cast Iron Gear Pumps

Product Overview: The GPC4 Series is the definitive “endurance” power source for industrial heavy-duty hydraulic systems. Featuring an all-cast-iron construction, this series is engineered specifically to withstand high pressures, shock loads, and harsh operating environments. This range features core single and tandem models: GPC4-40-2E2F4-30, double pumps GPC4-20-20-B1F4-30L, GPC4-80-40-2E2F4-30-R, and the flow-optimized GPC4-40-H12F3R-30R. The split cast-iron housing combined with precision-ground gears ensures maximum reliability under continuous 25 MPa high-pressure conditions.

Key Technical Advantages:

• Heavy-Duty Cast Iron Construction: Utilizing high-strength ductile iron, these pumps offer superior mechanical properties and fatigue resistance, preventing deformation or cracking under extreme temperature fluctuations and pulsating pressures.

• 100% Direct Replacement: Manufactured strictly to SAE or international mounting standards. Suffixes like 2E2F4 or B1F4 guarantee that mounting flanges, drive shafts (Keyed/Splined), and port configurations match your original equipment seamlessly.

• Tandem/Multi-Stage Versatility: Supports double and multi-stage configurations (e.g., GPC4-80-40), allowing a single drive shaft to power two independent circuits (80ml + 40ml), reducing energy consumption and installation footprint.

• Efficient Axial Gap Compensation: Equipped with automated pressure-compensated floating side plates, maintaining volumetric efficiency above 93% during long-term operation, effectively minimizing oil overheating.

• Target Applications: Dump truck hoist systems, mining machinery, concrete mixer drives, large-scale harvesters, and industrial shearing equipment.
