JHP3-P7600 Gear Pump
1. Product Overview
2. Structural Features
-
Patented Roller Bearing System: Equipped with U.S. patented pressure-controlled roller bearings, the pump’s service life is increased by 30% compared with conventional products. The bearing system is optimized for high-pressure working conditions, effectively balancing radial forces and reducing wear, ensuring stable operation even under long-term full-load conditions.
-
Dual-Patented Secondary Sealing: Adopting Sino-U.S. dual-patented secondary sealing structure, it significantly enhances sealing performance and pressure resistance, effectively preventing oil leakage in high-pressure environments. The special surface-treated side plates feature excellent pressure resistance and wear resistance, further improving the pump’s overall reliability.
-
SAE Standard Compatibility: The connection dimensions fully comply with SAE standards, including SAE “C” type shaft and various flange connections. The precision-machined involute spline ensures smooth power transmission, minimizing flow and pressure pulsation, and reducing operating noise.
-
Wide Displacement Adaptability: Covering 11 displacement models from 33.1mL/r to 198.8mL/r, matched with different gear widths (1/2” to 3”). The fixed bimetal side plates realize automatic clearance compensation, maintaining high volumetric efficiency during long-term operation.

5. Operational & Customization Notes
-
SAE standard connection is adopted, so ensure the matching degree of shaft and flange during installation. The coaxiality error between the pump shaft and power source shall be ≤0.1mm to avoid abnormal wear of bearings and splines.
-
Before initial startup, fill the pump with hydraulic oil and exhaust air completely. It is recommended to use high-quality hydraulic oil and configure a 10μm precision filter to maintain oil cleanliness and extend service life.
-
Customization scope includes gear width, oil port size (compatible with NPT thread/flange), nameplate and logo. MOQ for logo customization is 100 units, with a unit additional cost of $5; nameplate customization MOQ is 100 units, $2 per unit.
-
Packaging: Wooden case + foam padding for safe transportation. Warranty: 12 months for non-human damage, with professional after-sales technical support provided.
