1GG External Gear Pump Manufacturers

1GG Gear Pump  Overview

The 1GG series is a compact, high-efficiency fixed-displacement external gear pump engineered for cost-effective, reliable performance in a wide range of hydraulic systems. Designed for space-constrained applications, it delivers an excellent power-to-weight ratio, making it an ideal choice for direct mounting on power take-offs (PTOs) and mobile equipment where dependability and efficiency are key.

Features and Benefits

• Compact, Lightweight Construction:

  The 1GG series features a rugged, die-cast aluminum alloy body and end covers, providing a high strength-to-weight ratio compared to heavier alternatives. This robust yet lightweight design minimizes installation footprint, reduces overall system weight, and ensures structural integrity under typical operating conditions, supporting long service life in various industrial and mobile environments.

• High-Efficiency External Gear Design:

  Utilizing precision-machined external gear pairs, the 1GG series delivers consistent, smooth fluid flow with low pulsation. The design inherently provides reliable performance with standard hydraulic fluids, offering excellent volumetric efficiency at typical operating pressures. This simple, proven design is easy to maintain and tolerant of a wide range of operating conditions.
• Pressure-Compensated Axial Clearance Control:

  Equipped with pressure-balanced wear plates or bushings, the 1GG series automatically optimizes internal clearances between gear faces and the housing. This minimizes internal fluid bypass and friction, maintaining high mechanical efficiency and consistent power delivery across a broad range of operating temperatures and pressures.
• Reliable Pressure Capability:

  Engineered to handle continuous operating pressures up to 210 bar (3,000 psi), the 1GG series features high-quality alloy steel gears and precision components. It provides stable, reliable power for standard hydraulic actuators and circuits, ensuring dependable performance in light to medium-duty applications.
• Versatile Displacement and Installation Flexibility:

  The 1GG series offers a versatile range of displacements (from 1.3 to 13.5 cc/rev) and supports standard SAE mounting and port configurations. With multiple shaft and port options, it provides excellent installation flexibility for a wide variety of mobile machinery, agricultural equipment, and general industrial applications.

Certifications & Quality Assurance

1GG 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.
