Parker P6S P7P Piston Pump Axial Variable Pump
The P6S series is the successor and upgraded product of Parker PVplus series pumps, representing Parker's latest achievements in the field of industrial hydraulic pumps. It adopts a mature inclined disc design and achieves high-performance output in a compact size by optimizing key components such as bearings, sliding shoes, and port plates.
Main features and advantages
1. Extremely high power density
Compact structure, relatively light weight, but able to work continuously under high pressure, very suitable for installation of equipment with limited space.
2. Excellent overall efficiency
By optimizing the bearing design and pressure balancing the distribution plate, friction losses have been significantly reduced.
The efficient sliding shoe inclined plate pair design reduces volume loss and mechanical loss.
This means lower energy consumption, less heat generation, and longer lifespan.
3. Excellent anti pollution ability
The robust design and optimization of key components make the P6S pump insensitive to oil contamination, improving reliability under harsh operating conditions and reducing the risk of early failure due to oil contamination.
4. Low noise operation
The innovative design of the distribution plate and precise manufacturing process effectively reduce pressure and flow pulsation, making the pump run quieter and helping to meet strict noise environmental standards.
5. Multiple control modes (determined by fields such as N1 in the model)
HD: Pressure compensation control. The pump automatically reduces its displacement to zero at the set pressure, maintaining a constant system pressure, saving energy, and reducing heat generation. This is one of the most commonly used control methods.
AA: Load sensitive control. The output flow of the pump only meets the requirements of the actuator and is independent of the load pressure. Achieving on-demand distribution of system flow is the core of an efficient and energy-saving system.
DA: Torque control. By sensing the outlet pressure of the pump, the displacement is automatically adjusted to ensure that the absorbed torque of the pump does not exceed the set value, which is used for engine power matching.
NV: Constant power control. Similar to torque control, ensuring a constant input power to the pump.
ET: Electro hydraulic proportional control. The stepless adjustment of pump displacement or pressure setting value through external electrical signals (such as 0-5V, 4-20mA) is the basis for achieving intelligence and precise control.
FC: Constant flow control.
SC: Manual servo control.
6. Long lifespan and high reliability
Adopting heavy-duty bearing design, with strong load-bearing capacity.
The validated slide shoe and plunger design ensures a long service life.
Can be used in situations with strict work cycle requirements.
