Parker PV040R1K1T1VMMC Open Circuit Pumps High Precision Long Life New

Product Description:

The following is a comprehensive analysis of the advantages and characteristics of PARKER open pumps (mainly axial piston pumps and gear pumps) and precautions for use:

‌1. Advantages and characteristics‌

‌Axial piston pumps (such as PV series)‌
‌High efficiency and energy saving‌

Adopting a swash plate variable design, the flow rate is automatically adjusted according to system requirements, and the energy consumption is reduced by more than 30% compared with a fixed-displacement pump, reducing system heating.

Dynamic pressure compensation technology optimizes energy distribution, and the efficiency remains stable under high-pressure conditions.

‌High precision and fast response‌

The 9-piston structure is combined with pre-compression volume technology, and the flow pulsation is <±1.5%, and the output is stable.

The response time is ≤50ms, and high-frequency action switching is supported (such as injection molding machine mold closing control).

‌High reliability design‌

The high-strength cast iron housing and FEM optimized structure can withstand a peak pressure of 350bar and increase the life by 40%.

The bearing load capacity is improved, impact and vibration resistance, and it is suitable for harsh working conditions of engineering machinery.

‌Modularity and compatibility‌

The through-shaft drive design supports multi-pump series connection and is compatible with gear pump or vane pump integration.
Provides a variety of control options such as power regulator and pressure cut-off, suitable for complex hydraulic circuits.
‌Gear pump (such as GP/P16 series)‌ ‌

Compact and durable structure‌ ‌

Die-cast aluminum housing lightweight design, high power density, flexible installation. ​Hydrostatic clearance compensation technology, minimal leakage under high pressure (230bar rated). ​ ‌Low noise and pollution resistance‌ ​Optimized tooth design, 15dB (A) lower noise than traditional pumps. ​Sliding bearings tolerate oil contamination, NAS 1638 level 9 cleanliness can be stable operation. ​ ‌

Economical and easy maintenance‌ ​

The cost is 30% lower than that of plunger pumps, suitable for medium and low pressure systems. ​Nitrile rubber seals are standard configuration, with a long maintenance cycle (≥5000 hours). ​ ‌

II. Precautions for use‌ ‌

General requirements‌ ‌Oil management‌ ​Axial piston pumps require NAS 1638 level 7 cleanliness (ISO 16/13), and gear pumps require NAS 1638 level 9. ​Oil temperature control: continuous operation ≤60℃, short-term peak ≤80℃ (fluorine rubber seal is selected for high temperature environment).

‌Installation specification‌

The oil drain port of the axial piston pump must be upward, the pipeline back pressure is less than 0.2MPa, and the oil tank is returned independently.
Avoid negative pressure at the oil inlet of the gear pump, and the recommended oil suction height is ≤500mm.

‌Electrical and load control‌

The variable pump needs to be matched with a dedicated controller (such as PV series with VT amplifier), and over-power curve operation is prohibited.
For high-frequency start-stop conditions (such as forging presses), the single high pressure duration is ≤6 seconds.
