PV152R1EFO2 Parker Denison PV15 Variable Displacement Axial Piston Pump 34.2 cc

Product Overview

The PV152R1EFO2 (corresponding to PV152R1EC00 and PV15-2R1E-C00-CW) is a Parker Denison PV15 series open-circuit variable displacement axial piston pump. Featuring a high-strength cast-iron housing, pressure-compensator control and high volumetric efficiency, it delivers stable flow and pressure for industrial and mobile hydraulic systems. Manufactured to exact original Denison dimensions and interfaces, the pump offers complete interchangeability and can replace genuine PV15 units without modification to piping or mounting. Every unit undergoes 100% simulated operating-condition testing to ensure pressure, flow and noise performance meets or exceeds OEM standards, making it ideal for applications demanding high reliability and long service life.

Key Technical Advantages

1. High-strength cast-iron housing combined with precision-machined swashplate and piston assemblies provides excellent structural rigidity and resistance to deformation under high pressure, extending bearing and seal life.
2. Fast pressure-compensator response (approximately 50 ms off-stroke, 120 ms on-stroke) precisely matches system demand, reducing energy consumption and overflow heat generation.
3. High volumetric efficiency design with optimized valve plate delivers low operating noise, suitable for noise-sensitive industrial environments.
4. Full dimensional and interface interchangeability plus 100% simulated duty-cycle testing guarantees that mounting dimensions, port locations, shaft extension and control interfaces match original Denison PV15 pumps exactly, enabling drop-in replacement without system re-commissioning.
5. Multiple control options (pressure compensator, remote, load-sensing, etc.) provide application flexibility and enhanced system reliability.

Application Areas

Injection molding machines, die-casting machines, metal-forming equipment, industrial power units, port machinery, auxiliary circuits on mobile equipment, machine-tool hydraulic systems, and test benches requiring stable high-pressure variable flow in open-circuit configurations.

Expert Maintenance Tips

Verify shaft rotation matches system requirements (this model is CW) before installation. Ensure adequate inlet supply to prevent cavitation. Use anti-wear hydraulic oil meeting ISO 4406 cleanliness standards (recommended viscosity range 16–160 mm²/s) and keep case drain pressure below 0.7 bar. On first start-up, run at low pressure and low speed to confirm absence of abnormal noise or leakage before gradually increasing pressure. Inspect shaft seals and compensator settings every 2000–3000 operating hours; replace seal kits as needed to maintain high volumetric efficiency.
