GBHZA-F Series Gear Pump

GBHZA-F Series Gear Pump

Overview

GBHZA-F Series Gear Pumps are engineered for high-pressure performance, exceptional reliability, and long service life. Designed with a high-strength aluminum alloy body and precision-engineered gears, these pumps provide consistent hydraulic power for material handling, construction, and agricultural machinery, making them the preferred choice for OEM replacements in brands like Toyota, Komatsu, and Mitsubishi.

Features and Benefits

• Extended Pump Life: Exceptional durability achieved through high-grade wear-resistant materials, specialized surface-treated gears, and the use of high-load DU bushings for superior lubrication.

• Quiet and Smooth Operation: Advanced gear tooth profiles and a precision-machined housing reduce fluid pulsation and mechanical vibration, maintaining low noise levels during high-pressure operation.

• High Efficiency & Energy Saving: Features a pressure-loading design that maintains high volumetric and mechanical efficiency, minimizing internal leakage and heat generation.

• Compact & Modular Design: Standardized ISO and SAE mounting flanges and shaft options allow for easy installation in tight spaces and seamless integration into existing systems.

• Versatile Combinations: Supports tandem (double) or triple pump configurations, providing a cost-effective and flexible solution for multi-circuit hydraulic packages.

Certifications & Quality Assurance

Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
