Applications
Applications
Construction & Road Machinery: A primary choice for excavator attachments, concrete mixers, and mobile cranes, where the compact 3GP frame integrates easily with Power Take-Off (PTO) units to provide reliable lifting and positioning power.
Agricultural Equipment: Optimized for tractors, harvesters, and sprayer systems, where the robust construction and bushing design ensure long-term durability against fluid contamination and high-frequency cycles of outdoor use.
Commercial Refuse & Recycling: Widely used in refuse trucks and compactors that require high-cycle, high-pressure stability to manage rapid compaction and unloading operations.
Material Handling & Logistics: Ideal for forklifts, truck tail-lifts, and hydraulic ramp systems, offering a durable and space-efficient power source that maintains high efficiency under heavy load conditions.
Specialized Industrial & Off-Highway Equipment: Frequently employed in forestry machinery, utility vehicles, and drilling rigs, where the 3GP handles variable load shocks and thermal stress common in demanding work environments.
Factory&FAQ
3GP 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.
Robust Construction: The three-piece aluminum body with cast iron covers minimizes deflection under high pressure, maintaining tight clearances and longer service life.
Pressure-Balanced Bushing & Wear Plate Design: It uses advanced pressure-balanced components to reduce friction, improve efficiency, and resist thermal shock and fluid contamination better than many standard gear pumps.
Modular Installation Flexibility: It supports multiple flange options (SAE B, European), shaft configurations (keyed, splined), and port orientations, offering unmatched adaptability in cramped chassis environments.
The 3GP is a compact high-pressure specialist. Depending on the specific displacement, the series typically handles:
Continuous Pressure: Up to 3,600 PSI (250 bar).
Intermittent/Peak Pressure: Up to 3,900 PSI (270 bar) (varies by model).
This robust pressure rating makes the 3GP ideal for driving high-force lifting, compaction, and actuation systems on professional-grade utility vehicles.
Yes, the 3GP is a high-quality alternative to other premium Group 3 gear pumps. It is often used as a replacement or upgrade for:
Old Galtech 3SP Series.
Parker/Commercial Intertech P330 Series.
Metaris MH330 Series.
Casappa KP30 Series.
To ensure a successful swap, verify the Mounting Flange (SAE B or European), Shaft Type (keyed, splined), and Displacement to match your existing system.
To protect the precision bushings and hardened steel gears, 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 bushing lubrication. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the pump components.
The maximum speed varies with displacement:
Low Displacement (19–34 cc/rev): Up to 3,500 RPM.
Mid Displacement (37–53 cc/rev): Up to 3,300–3,000 RPM.
High Displacement (62–77 cc/rev): Up to 2,500–2,200 RPM.
Operating within these ranges ensures optimal performance, efficiency, and service life.

3GP 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.
