Leading Pressure-Limiting Variable Technology

Distinguished from the previous blade pump series (1PV2V4 double-acting fixed displacement, 0513 single-acting eccentric adjustable variable) and gear pump series (AZPF, GSP2, PGH), the Blade Oil Pump PV7 Series PV7-1X/40-45RE01MC0-10 is an advanced pressure-limiting variable vane pump series independently developed by our company, mainly positioned for high-medium pressure hydraulic systems (rated pressure 280bar, peak pressure 315bar). 

Different from the manual eccentric adjustment of the 0513 series, the PV7 series adopts an intelligent pressure-limiting variable mechanism: when the system pressure approaches the set value, the pump will automatically reduce the displacement, fundamentally avoiding energy waste caused by fixed-displacement pumps and manual adjustment variables, which is more in line with the global energy-saving and environment-friendly development trend. 

This series inherits the advantages of low noise and small flow pulsation of vane pumps, and integrates the characteristics of intelligent pressure limiting and automatic variable, making it more suitable for high-pressure, large-flow hydraulic systems that require stable operation and energy saving, and filling the gap of high-pressure pressure-limiting variable vane pumps in our company's product line.

Model Interpretation

The model code PV7-1X/40-45RE01MCO-10 has a clear and intuitive coding logic, which is easy for purchasers to quickly identify product parameters and configuration without professional hydraulic knowledge: 

PV7 represents the pressure-limiting variable vane pump series; 

1X indicates the single-stage pump core structure, ensuring stable operation and easy maintenance; 

40-45 refers to the adjustable displacement range of 40-45 cm³/rev, which can flexibly adapt to the flow demand of different working conditions; 

RE01 denotes the standard flange connection (conforming to ISO 3019/2) and keyway drive shaft, which is compatible with most industrial equipment installation standards; 

MCO stands for the integrated pressure-limiting control module, which can automatically adjust displacement according to system pressure, realizing intelligent energy saving; 

10 represents the high-pressure sealing grade, ensuring no oil leakage under high-pressure working conditions. 

As the core model of the PV7 series, Blade Oil Pump PV7 Series PV7-1X/40-45RE01MC0-10 is specially optimized for high-pressure, large-flow working scenarios, with compact structure, intelligent control and strong environmental adaptability, and is widely used in high-end industrial equipment and large hydraulic systems.

Comparative Advantages

Blade Oil Pump PV7 Series PV7-1X/40-45RE01MC0-10 has obvious advantages in pressure resistance, variable performance and stability, which are significantly different from the previous vane pump and gear pump series.

Its adjustable displacement range is 40-45 cm³/rev, rated pressure is 280bar, peak pressure can reach 315bar, which is 70bar higher than the 0513 series and 30bar higher than the 1PV2V4 series, fully meeting the high-pressure demand of heavy-duty hydraulic systems.

The volumetric efficiency is up to 94%, which is 3% higher than that of ordinary pressure-limiting variable vane pumps, effectively reducing energy loss. The model adopts 16-piece high-precision vane design, with a flow pulsation rate ≤ 2%, which is lower than that of the 0513 series (≤3%), and the noise level is as low as 56dB (1m away), creating a quieter working environment for industrial sites.

Unlike the sliding bearings of the 0513 series and ball bearings of the 1PV2V4 series, this model adopts high-precision angular contact ball bearings, which can bear both radial and axial loads, reduce friction loss, and extend the service life to 14000 hours, far higher than the industry average.

In addition, it has excellent self-priming performance, with a self-priming height of up to 1.1m, which can effectively avoid dry operation and adapt to complex oil supply conditions in high-pressure working environments. The pump also adopts a pressure compensation design, which can automatically adjust the internal pressure, reduce internal leakage, and ensure stable operation even under long-term high-pressure continuous operation.
