PV270R9K1T1NWLCK0366 Parker Axial Piston Pump 270 cm³ 350 bar

Product Overview

The PV270R9K1T1NWLCK0366 and PV270R9K1T1WMM1K0069 belong to the Parker Hannifin PV series of open-circuit variable displacement axial piston pumps (sizes covering PV046, PV063, PV080, PV092, PV140, PV180, PV270, PV360). Featuring a swash-plate design, flow is proportional to drive speed and displacement and is infinitely variable, offering low noise, fast response and high self-priming capability. Fully interchangeable with genuine Parker units, these pumps enable direct drop-in replacement without modification to mounting interfaces or piping. Every unit undergoes 100% simulated operating-condition testing to ensure high efficiency and reliability under high pressure.

Key Technical Advantages

1. High Power Density & Pressure Capability: Continuous rating of 350 bar and peak of 420 bar combined with compact swash-plate design deliver high flow in limited space for heavy-duty industrial applications.
2. Low Noise & Fast Response: Pre-compression chamber significantly reduces system noise. Large control piston ensures smooth and rapid response.
3. High Self-Priming Capability & Modular Controls: Excellent self-priming performance. Modular controls allow field convertibility and support multiple pressure/power compensation options.
4. Robust Cast-Iron Housing & Extended Service Life: High-strength cast-iron housing ensures reliable quiet operation. High-load bearings and precision manufacturing extend service life.
5. True Interchangeability & Thru-Drive Capability: Fully compatible with OEM mounting dimensions. Thru-drive option transmits 100% nominal torque for multi-pump combinations.

Application Areas

• Industrial hydraulic systems (presses, injection moulding machines, test stands)
• Auxiliary systems on construction machinery
• Metallurgical and forming equipment
• Port and material-handling equipment
• Any fixed or mobile application requiring open-circuit variable displacement performance

Expert Maintenance Tips

1. Ensure proper flange alignment during installation; use a flexible coupling and avoid excessive radial/axial loads. Position the drain port as high as possible.
2. Use anti-wear hydraulic oil meeting ISO cleanliness (at least 16/13) and viscosity requirements; system filtration should be at least 10 μm. Thoroughly bleed air before initial start-up.
3. Regularly monitor inlet pressure (min. 0.8 bar absolute) and case drain pressure (continuous ≤0.5 bar) to prevent cavitation or over-pressure.
4. During service, inspect pistons, cylinder block and valve plate for wear; replace complete rotating groups when necessary. Store long-term units in a dry environment and rotate the shaft periodically.
