Hydraulic Gear Pump Description
Our PGP330 hydraulic gear pump is identical to the original PGP330
in dimensions, interfaces (SAE/SI shaft, flange, and ports),
mounting holes, and performance parameters. It supports single-pump
and multi-section configurations for seamless direct replacement
without any system modifications.
Our PGP gear pumps are perfectly compatible with Parker original
parts, with a complete size fit. Performance and quality are no
less than original parts, with faster delivery and more competitive
pricing.
Runhe Hydraulics specializes in the production and export of
hydraulic cylinders, hydraulic gear pumps, hydraulic gear motors,
and spare parts, committed to providing top-tier quality and
after-sales service. Our highly competitive prices and superior
quality have earned us a growing number of partners.

Hydraulic Gear Pump Advantages
1. Fits the entire PGP series original factory structural
specifications, with key installation dimensions matching,
requiring no adjustment to the equipment base.
2. Oil port connection method, drive shaft adapter type, and
rotation direction all conform to the original factory settings,
ensuring smooth connection with the original system's power input.
3. Wear parts are interchangeable with original factory spare
parts; gear assemblies can be replaced individually, reducing
maintenance costs.
4. Three-section structure for easy disassembly, allowing for quick
replacement of core components.
5. 50-70% lower procurement cost than the original factory, with
performance and quality 100% same with the original factory
Operating Instructions
1. Installation & Rotation: Drive pump only in specified
direction (CW or CCW). Reverse rotation damages shaft seal. Inlet
port is larger; outlet is smaller.
2. Piping Connections: Use short, straight suction line without
sharp bends. Maintain inlet pressure 0.8–2 bar abs to avoid
cavitation. Fill pump and lines with clean hydraulic oil.
3. Pre-Start Preparation: Ensure system is fully primed to prevent
dry running. For cold starts, briefly jog pump; avoid hot oil
entering cold pump.
4. Operating Parameters: Strictly follow manual limits: max speed
(3000 rpm for PGP315/330, 2400 rpm for PGP350/365), continuous
pressure 241 bar, temperature, and oil viscosity. Keep system clean
and check filters regularly.
5. Multi-Section Pumps: Rear sections are driven through the front
pump; ensure correct configuration.
