Applications
Applications
Mobile Construction & Utility Vehicles: Ideal for aerial lifts, skid‑steer loaders, and compact excavators, where the aluminum housing reduces vehicle weight while delivering consistent power for lifting, tilting, and auxiliary functions.
Agricultural Equipment: Commonly used in tractors, harvesters, and fertilizer spreaders, where its resistance to shock loads and fluid contamination ensures reliable performance in outdoor field environments.
Material Handling Systems: Perfect for forklifts, pallet jacks, and truck tail‑lifts, offering a durable and space‑efficient power source that maintains high efficiency under heavy load conditions.
Snow & Ice Control: Optimized for salt spreaders and small plow systems, where the corrosion‑resistant aluminum construction and pressure‑balanced design provide long‑term durability against moisture and frequent duty cycles.
Commercial Refuse & Recycling: Widely applied in compact waste collectors and bin lifters, delivering the high‑cycle, high‑pressure stability needed for fast compaction and unloading operations.
Light Industrial Hydraulics: Used in presses, machine tools, and conveyor systems, where its smooth flow and low noise operation improve both productivity and workplace comfort.
Factory&FAQ
25500 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: Compared to cast iron pumps, the 25500 significantly reduces overall system weight, making it ideal for mobile equipment payload-sensitive designs.
Pressure-Balanced Wear Plate Design: It utilizes precision pressure-compensated wear plates that automatically adjust internal clearances, minimizing leakage and maintaining high efficiency even under varying pressure and temperature conditions.
Compact & Versatile Porting: Standard with both side and rear port configurations, the 25500 offers greater installation flexibility in tight chassis environments than many fixed-port designs.
Continuous Pressure: Up to 3,600 PSI (248 bar).
Intermittent/Peak Pressure: Up to 4,000 PSI (276 bar).
This robust pressure rating makes it suitable for powering a wide range of mobile equipment functions, from lifting to material handling.

Equivalent models from Parker, Commercial Intertech, or Metaris.
To ensure a successful swap, verify the Mounting Flange (SAE B), Shaft Type (13-tooth spline), and Displacement (19.7 cm³/rev) to match your existing system.
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).
Filtration: A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear and wear plate surfaces.
Rated Operating Speed: Up to 3,000 RPM.
Maximum Intermittent Speed: Up to 3,600 RPM.
