Applications
Applications
The G30 series provides a lightweight, high-efficiency power solution specifically tailored for mobile and industrial hydraulic systems where compact size, low weight, and reliable medium-to-high pressure performance are required:
Forklifts & Material Handling: The G30 is widely used in counterbalance forklifts, reach trucks, and pallet stackers, where its compact aluminum design and consistent pressure output support smooth lifting and tilting operations.
Construction Machinery: Ideal for small excavators, skid-steer loaders, and backhoe loaders, where it powers auxiliary systems like boom, bucket, and steering functions with dependable, low-noise performance.
Agricultural Equipment: Commonly found in tractors, harvesters, and fertilizer spreaders, where it handles variable load shocks and outdoor operating conditions while maintaining high volumetric efficiency.
Aerial Work Platforms: Used in scissor lifts and boom lifts, where its light weight and compact footprint make it easy to integrate into tight chassis spaces while delivering reliable lifting power.
Utility & Service Vehicles: Suitable for truck-mounted cranes, aerial bucket trucks, and tail-lift systems, where it offers a balance of power-to-weight ratio and installation flexibility for direct PTO-driven setups.
Industrial Hydraulic Systems: Applied to machine tools, conveyor systems, and general-purpose hydraulic power units, providing stable, cost-effective pressure for continuous-duty applications.
Factory&FAQ
G30 series pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The G30 is a high-performance, fixed-displacement external gear pump, designed for compact and light-weight hydraulic systems. Featuring a robust two-piece aluminum construction, it is specifically engineered for mobile equipment that requires high efficiency, reliable medium-to-high pressure output, and a superior power-to-weight ratio.
Lightweight Aluminum Housing: Compared to cast iron pumps, the G30’s aluminum construction significantly reduces overall system weight, making it ideal for mobile equipment where payload and fuel efficiency are priorities.
High-Efficiency Gear & Bearing Design: Utilizing precision-ground gears and high-quality sleeve bearings, the G30 offers lower noise and higher volumetric efficiency, reducing energy consumption during continuous operation.
Compact & Modular Design: With a smaller footprint and multiple port configurations, the G30 provides greater installation flexibility in tight chassis environments than many standard cast iron pump designs.
The G30 is a compact medium-to-high pressure pump. Depending on the specific displacement, the series typically handles:
Continuous Pressure: Up to 3,050 PSI (210 bar).
Intermittent/Peak Pressure: Up to 3,625 PSI (250 bar).
This pressure rating makes the G30 ideal for powering lifting, steering, and auxiliary systems on forklifts, construction machinery, and agricultural equipment.
Yes, the G30 is a high-quality, cost-effective alternative to many standard aluminum gear pumps. It is often used as a replacement or upgrade for:
BorgWarner/Commercial Intertech: 30 Series
Rexroth: AZPF Series
Casappa: PLP Series
To ensure a successful swap, verify the Mounting Flange (SAE A or B), Shaft Type (splined or keyed), and Displacement (cc/rev) to match your existing system.
To protect the precision gears and sleeve bearings, the following is recommended:
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt), though it can handle cold starts up to 2,000 SUS (430 cSt).
Filtration: Cleanliness is vital for bearing life. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear faces and bearings.
The G30 series is designed for reliable performance across a wide operating range:
Continuous Operating Speed: 600 to 2,400 RPM.
Maximum No-Load Speed: Up to 3,000 RPM.
Operating within these ranges ensures optimal efficiency, minimal noise, and extended service life.

G30 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.
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.
