Applications
Agricultural Machinery: A primary choice for tractors, harvesters, sprayers, and implement hydraulic systems, where the compact aluminum construction and efficient operation deliver consistent power for lifting, steering, and control functions.
Construction Equipment: Ideal for compact excavators, skid-steer loaders, aerial work platforms, and small cranes, offering durable and space-efficient hydraulic power under demanding, variable-load conditions.
Material Handling: Widely used in forklifts, pallet jacks, tail lifts, and conveyor systems, providing reliable high-cycle performance for lifting, tilting, and load-handling operations.
Commercial Vehicles & Truck-Mounted Systems: Suited for utility trucks, aerial lifts, and refuse collection equipment, where its high power-to-weight ratio and flexible mounting options integrate seamlessly with truck-mounted power take-off (PTO) setups.
General Industrial Hydraulics: Applied in machine tools, conveyor systems, and light-duty presses, delivering stable, efficient power for low-to-medium pressure circuits in factory automation and process equipment.
PGP505 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.
Lightweight Aluminum Housing: Unlike cast iron pumps that add significant weight, the PGP505’s high-grade aluminum frame delivers strength while reducing overall system weight, making it ideal for mobile applications where payload is critical.
High-Efficiency Gear & Bearing Design: Utilizing precision-machined spur gears and advanced journal bearings, it offers smooth, low-noise operation with consistent volumetric efficiency, even at varying speeds.
Flexible Port & Mounting Options: Available with side, rear, and end port configurations, plus standard SAE "A" mounting flanges, the PGP505 offers greater installation flexibility than fixed-port cast iron designs in cramped chassis environments.
The PGP505 is a compact high-pressure specialist. Depending on the specific displacement, the series typically handles:
Continuous Pressure: Up to 275 bar (4,000 PSI) for most models.
Intermittent/Peak Pressure: Up to 300 bar (4,350 PSI).
This robust pressure rating makes the PGP505 ideal for driving lifting, steering, and auxiliary hydraulic systems on agricultural, construction, and material handling equipment.
Yes, the PGP505 is a high-quality alternative to other premium compact aluminum gear pumps. It is often used as a replacement or upgrade for:
Casappa: PLP20 Series
Bosch Rexroth: AZPF Series
Marzocchi: GHP2 Series
To ensure a successful swap, verify the Mounting Flange (SAE A), Shaft Type (keyed or splined), and Displacement (cc/rev) to match your existing system.
To protect the precision gears and journal bearings, the following is recommended:
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) additive packages, compatible with aluminum components.
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 long service life. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging gear and bearing surfaces.
Maximum Speed: 3,000–4,000 RPM (varies by displacement; smaller displacements support higher speeds up to 4,000 RPM).
Minimum Speed: 500 RPM, ensuring stable operation at low engine speeds without cavitation or pressure drop.

PGP505 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.
