Every unit undergoes 100% simulated operating-condition testing to guarantee reliable output under rated pressure and speed. Ideal for OEMs and aftermarket applications demanding interchangeability, durability and consistency.

Technical Specifications

Model: AZPNF-11-028/016RDC0720KB-S0023
Material numbers: 0510767315 / R902650748
Type: High-Performance external gear tandem pump (fixed displacement)
Displacement: 28 cm³/rev (1st stage, Platform N) + 16 cm³/rev (2nd stage, Platform F)
Continuous pressure: approx. 210 bar (1st stage), up to 250 bar (2nd stage); typically 230 bar for combination
Intermittent / peak pressure: up to 230 bar (1st stage), up to 280 bar (2nd stage)
Maximum speed: 2800 rpm (at intermittent pressure)
Suction pressure: 0.7–3 bar absolute
Control: Fixed displacement
Direction of rotation: Clockwise (viewed on drive shaft, R)
Drive shaft: SAE J744 22-4 13-tooth splined
Mounting flange: SAE B 2-bolt (spigot dia. approx. 101.6 mm)
Port connections: DIN/SAE flange or threaded (per S0023 special version)
Weight: approx. 8.9 kg
Housing: High-precision aluminum casting, phosphated with precision cover fixation
Bearings: Plain bearings for heavy-duty applications

Key Technical Advantages:

Precision machining and pressure-compensated gap sealing: Extremely tight gear-to-housing clearances maintain high volumetric efficiency under high pressure, minimizing internal leakage and heat generation.
Heavy-duty plain bearings: Optimized for high-pressure and shock-load conditions, delivering extended bearing life in continuous heavy-duty service.
Full interchangeability: Mounting dimensions, shaft end, flange and ports match original Rexroth AZPNF series exactly – true drop-in replacement.
Low noise and high stability: Optimized tooth profile and reduced pressure pulsation result in quieter operation and lower system vibration.
100% simulated-condition testing: Every unit is tested under actual working pressure, speed and load before shipment, ensuring consistent performance and reliability.

Application Areas:

Construction machinery (auxiliary circuits on excavators and loaders), agricultural equipment, forklifts, port machinery, industrial hydraulic power units, mobile cranes and any high-pressure multi-circuit systems requiring independent oil supply. Particularly suited for space-constrained, high-pressure applications with strict interchangeability requirements in both OEM and aftermarket use.

Expert Maintenance Tips:

Install strictly according to original rotation and orientation markings; ensure proper shaft alignment with the prime mover to avoid additional radial or axial loads. Bleed the system thoroughly and verify suction-line sealing before first operation to prevent cavitation. Use hydraulic oil meeting DIN/ISO standards (recommended operating viscosity 20–100 mm²/s) and maintain cleanliness class ISO 4406 20/18/15 or better. Monitor shaft-seal and bearing temperatures regularly and stay within the allowed ambient temperature range. For long-term storage, seal all ports and fill with preservative oil. When replacing, always select the identical model or a fully tested interchangeable unit to maintain system matching.
