Parker pvp series hydraulic pump sample
Parker Hannifin PVP Series is a range of high-performance variable displacement swashplate axial piston pumps, engineered for both industrial and mobile applications that demand stability, efficiency, and long service life. This catalog sample provides detailed specifications, model decoding, key features, and application guidelines to support selection, installation, and maintenance.
1. Product Overview
The PVP Series is designed as variable displacement swashplate axial piston pumps, primarily used in open-circuit hydraulic systems. Available as single pumps or multi-section pumps, they are widely recognized for their reliable performance, low noise, and easy maintenance, making them suitable for a variety of harsh working environments. The series covers a displacement range of 16-140 cc/rev, with rated pressure up to 250 bar (3625 psi), meeting the needs of medium-to-high pressure hydraulic systems.

3. Model Range & Decoding
3.1 Model Range
The PVP Series includes multiple models to cover different displacement and pressure requirements, including: PVP016, PVP023, PVP033, PVP041, PVP048, PVP060, PVP076, PVP100, PVP140, etc. Typical models include PVP1636R212, PVP2336BR2MP21, PVP3336R2H, etc..
3.2 Model Decoding (Taking PVP2336BR2MP21 as an Example)
-
PVP: Product series identifier (Parker Variable Displacement Axial Piston Pump).
-
23: Nominal displacement (23 cm³/rev).
-
36: Rated working pressure (360 bar for this model).
-
B: Built-in pressure compensator.
-
R2: Rotation direction (right rotation, viewed from the drive end).
-
M: Mounting flange type (SAE A-type).
-
P21: Control module combination (including pilot pressure feedback, electro-hydraulic proportional servo valve interface, and integrated drain monitoring channel).
4. Key Features
-
Adopts a new swashplate through-shaft structure and large compensation piston, significantly reducing vibration, noise, and flow fluctuation; FEM-optimized pump body structure lowers noise levels and enhances structural stability.
-
Precision processing technology: Cylinder bore machining tolerance is strictly controlled, and the valve plate surface is treated with micron-level laser hardening to improve wear resistance and service life.
-
Equipped with a standard pressure compensator, maintaining stable pressure difference throughout the service life; Multiple control options available, including pressure compensation, power compensation, and electro-hydraulic proportional control (PWM signal adjustment for servo valve opening to achieve linear flow control).
-
100% nominal torque through-shaft transmission structure, allowing combination installation of multiple pumps with the same specification and mounting flange.
-
Low energy consumption and high efficiency, suitable for long-term continuous operation; Active pressure relief function of the compensation system reduces pressure peaks during zero-flow variable adjustment.
-
Easy maintenance: Modular design, convenient disassembly and assembly, reducing maintenance time and cost.
5. Applications
The PVP Series is widely used in various industrial and mobile scenarios that require stable and efficient hydraulic power supply, including:
-
Construction machinery (excavators, loaders, concrete mixers).
-
Marine industry and aviation field.
-
Oil and gas industry, metallurgy, and chemical industry.
-
Automated production lines (e.g., automotive parts manufacturing lines, compatible with PLC control systems).
-
Heavy-duty equipment and precision hydraulic systems requiring low pulsation and fast response.
6. Installation & Maintenance Notes
-
Installation should comply with VDMA-24560 and ISO 3019 standards; Ensure correct alignment of the pump and drive device to avoid shaft deviation causing wear.
-
The minimum compensation pressure is 12-15 bar, ensuring stable operation of the compensation system.
-
Regularly check the oil quality and replace hydraulic oil according to the operating environment; Avoid mixing different types of hydraulic oil.
-
Check the tightness of the pump body and connecting parts regularly to prevent oil leakage; Clean the filter element regularly to avoid clogging affecting pump performance.
-
For German-manufactured original models, ensure that the installation and maintenance comply with the factory verification standards to maintain product performance.
