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.
