PV series

Main advantages and scope of application of Parker PV series hydraulic pumps

Parker's PV series hydraulic pumps (and their upgraded PV plus version) are the recognized industry standard for heavy-duty industrial and mobile applications. Their popularity is due to their combination of high performance, reliability and flexibility. The key benefits of this series are listed below.

Key advantages of Parker PV hydraulic pumps:

1. High power and performance. The pumps are designed to operate at consistently high pressures of up to 350 bar (nominal) and 420 bar (peak). This provides high power density, allowing for the transfer of large amounts of energy from a relatively compact unit, which is critical for modern technology.
2. Reliability and durability. The design of the PV series pumps is designed to operate in the most difficult conditions.
   • Sturdy construction: The use of high-quality materials and a massive housing optimized using the finite element method (FEM) guarantees a long service life.
   • Reliable bearings: Reinforced shaft bearings are capable of withstanding significant external radial and axial loads.
3. Low noise and pulsation One of the main advantages is quiet operation.
   • Built-in pre-compression volume: This technology significantly smooths out pressure pulsations that occur during operation and significantly reduces the overall noise level of the hydraulic system.
   • 9-piston design: Promotes more uniform fluid delivery and reduced vibrations.
4. High efficiency and energy saving. Parker PV pumps have a high efficiency (typically over 90% overall efficiency). This means minimal energy loss in heating the working fluid, which reduces operating costs and cooling system requirements. Various control options, such as Load Sensing, allow the pump to deliver only the amount of oil needed, further saving energy.
5. Fast response and precise control. The PV series offers a wide range of highly dynamic regulators (pressure compensators, power compensators, Load Sensing, electro-proportional control). They provide a very fast response to changing system needs (response time can be less than 70 ms), which increases the performance and accuracy of equipment operation.
6. Versatility and configuration flexibility. Wide range of sizes: The range covers displacements from 16 to 360 cm³/rev, allowing you to choose the optimal pump for any task.
   • Modular design: Allows easy change of regulator type or shaft and flange configuration.
   • Possibility of tandem execution: The presence of a through shaft (Thru-drive) allows you to connect multiple pumps (for example, two PV pumps or a PV pump with a pump of another series), saving space and reducing the number of drive motors.
7. Excellent suction characteristics The pumps have a high self-priming rate, which allows them to operate stably at high speeds without the risk of cavitation and simplifies their installation above the tank level.

These advantages make Parker PV series pumps an ideal choice for presses, injection molding machines, metallurgical equipment, construction and mining equipment, as well as for marine hydraulic systems.
