Parker PV092 high-pressure variable axial piston pump

Parker PV092 high-pressure variable axial piston pump, designed specifically for open circuit heavy-duty hydraulic systems. Adopting a slanted disc 9-plunger structure, with a nominal displacement of 92cm #179; /rev， Rated pressure 350 bar, peak pressure 420 bar, volumetric efficiency ≥ 95.2%. Integrated pre compression chamber and pressure compensation control, low flow pulsation, fast response, and low noise.

In terms of structural design, PV092 adoptsIntegrated high-strength gray cast iron shellAfter aging treatment to eliminate internal stress, it has strong rigidity, vibration resistance, and impact resistance. The surface nickel phosphorus coating (25 μ m) enhances corrosion resistance and is suitable for harsh working conditions such as dust, humidity, and salt spray. The internal core is9-plunger inclined disc structureThe plunger and cylinder body adopt precision grinding technology, with extremely small clearance between them; integrationPre compression chamber technologyThe flow pulsation is reduced to below 5%, and the operating noise is below 68dB, significantly improving the system stability and working environment. Equipment for inclined plate adjustment mechanismDouble spring pre tensioning+servo valve pilot controlResponse time ≤ 80ms, reducing pressure overshoot by 41% compared to traditional pumps, effectively suppressing water hammer effects, and protecting pipelines and valves.

In terms of performance configuration, PV092 has a nominal displacement of 92cm ³/rev,Rated pressure 350bar, peak pressure 420barThe volumetric efficiency is ≥ 95.2%, and the flow rate reaches 138L/min at 1500rpm, balancing high pressure and large flow requirements. standard configurationPressure compensation variable controlIt can be infinitely adjusted within the range of 0-100% displacement, automatically matching the flow rate according to the load, reducing air consumption, energy saving and high efficiency; Optional power control, electro-hydraulic proportional control (compatible with CANopen communication), suitable for automation and intelligent control scenarios. adoptFluorine rubber double lip sealing componentIt is dustproof and waterproof up to IP54, with a medium temperature adaptability of -20 ℃~+80 ℃, and can withstand extreme temperatures of -40 ℃~+100 ℃ in a short time. It is compatible with mineral oil and fire-resistant hydraulic fluid (HFC ≤ 210bar), and is suitable for special working conditions such as chemical explosion-proof and food grade.

In terms of installation adaptability, the product complies withISO 3019/2 metric and SAE flange standardsSupports horizontal and vertical installation in multiple directions, with a tilt angle of up to ± 15 °, suitable for space limited scenarios such as ships and engineering machinery. The import and export adopt SAE flange connection (high pressure port 3/4 ', low pressure port 1-1/4'), which is easy to disassemble and has reliable sealing; supportThrough axis drive designIt can be combined with a single pump or multiple pumps in series, suitable for multi circuit hydraulic systems, and has strong expandability. Internally, it adopts forced lubrication and pressure relief protection to reduce wear and overload risks, with a design lifespan of up to 100000 hours, long maintenance cycles, and low operation and maintenance costs.

The product strictly follows Parker's global quality standards and has passed CE certification and ISO9001 system certification. Each unit undergoes multiple rigorous tests such as load, temperature rise, noise, and sealing before leaving the factory, ensuring stable and reliable performance. Widely used in chemical reaction kettle hydraulic drive, metallurgical rolling mill high-pressure system, ship servo/anchor power source, engineering machinery main pump, hydraulic power unit and other scenarios, it is the core preferred product for high-pressure, high-efficiency and high reliability hydraulic systems.
