Vickers single vane pump 35V/45V series
The Vickers 35V and 45V series are fixed-displacement single vane pumps designed for medium-pressure industrial and mobile hydraulic applications. With a balanced intra-vane design, they feature high volumetric efficiency, low noise operation, and long service life, making them widely used in injection molding machinery, marine hydraulic systems, petrochemical equipment, and other fields. This document details the model specifications and key technical parameters of the two series.
1. Model Nomenclature
The model code of Vickers 35V/45V series single vane pumps follows a uniform standard, and each segment represents specific product characteristics. The typical model format and explanation are as follows:
Example: 35V38A-1A22R
-
35V/45V: Series identifier, 35V and 45V represent different frame sizes, corresponding to different displacement ranges.
-
38: Displacement code, indicating the theoretical displacement of the pump (unit: cm³/r), and the specific corresponding value is shown in the parameter table below.
-
A: Port connection type, representing SAE 4-bolt flange connection (the common connection type for single vane pumps of this series).
-
1: Shaft type, 1 stands for standard shaft; other optional types include heavy-duty shaft (86) and splined shaft (11, 151).
-
A: Outlet position, indicating that the outlet is opposite to the inlet; optional positions include -90° CCW from inlet (B), inline with inlet (C), and -90° CW from inlet (D).
-
22: Design number, representing the 22nd design, which is famous for its reliability and versatility and is widely used in construction machinery.
-
R: Rotation direction, R stands for clockwise rotation (blank for clockwise by default); L stands for counterclockwise rotation.
2. Key Technical Parameters
The following parameters are theoretical values without considering efficiency and tolerances, and the actual values may have slight deviations based on working conditions and product batches. All units comply with international hydraulic industry standards.

3. Additional Specifications & Features
-
Vane Design: Adopts self-compensating vane design, which can automatically adjust the orbit to fit the cam ring even after wear, ensuring constant volumetric efficiency during service life.
-
Noise Level: Equipped with a 12-vane system for industrial applications, minimizing flow pulsation and keeping noise levels as low as 62 dB(A).
-
Hydraulic Fluid: Suitable for anti-wear industrial hydraulic oils or automotive crankcase oils; compatible with weakly acidic, alkaline media, HFD phosphate ester and HFC water glycol.
-
Maintenance: The cartridge is independent of the shaft, allowing easy flow capacity adjustment and on-site maintenance without removing the pump from the mounting bracket.
-
Volumetric Efficiency: Exceeds 90%, ensuring optimal performance and energy saving under harsh working conditions.
4. Notes
1. The maximum pressure and speed shall not be exceeded simultaneously to avoid damage to the pump.
2. Ensure full-flow filtration of hydraulic fluid in line with ISO standards to extend the service life of the pump.
3. The pump is not damaged during low-speed and high-pressure operation, as the pumping action starts only when the speed is high enough to throw the vane out.
4. For specific application scenarios and customized requirements, refer to the official Eaton Vickers product manual.
