Vickers vane pumps are widely used in machining centers due to their stable performance, low noise, high efficiency and strong anti-pollution ability. The following are the main series and typical models suitable for machining centers, covering single pumps and double pumps to meet different hydraulic system requirements of machining centers.

1. Single Vane Pump Series (Suitable for Single-Circuit Hydraulic Systems of Machining Centers)

1.1 V Series (General Medium-Pressure Series)

This series is designed for medium-pressure industrial applications, featuring a 12-vane structure for low noise and stable flow output, which is suitable for common machining center hydraulic circuits such as spindle clamping and feed drive. It adopts a cartridge design for easy maintenance without removing the pump from the mounting bracket.

Typical Models:

• 20V Series: 20VQ60A121AA20 (with pressure compensation valve), 20V-1P13P-11D11L, 20V-1S3S-1A20
• 25V Series: 25V14A1C22R, 25V17A1C22R, 25V19A1A22R
• 35V Series: 35V30A1C22R, 35V38A1C22R, 35V45A1C22R
• 45V Series: 45V42A1C22R, 45V60A1C22R (suitable for high-pressure clamping of gantry machining centers), 45V50A1C22R

1.2 V10/V20 Series (Small Displacement Precision Series)

This series is characterized by small displacement, high precision control performance and low noise, which is suitable for precision machining centers, small machining centers and auxiliary hydraulic circuits (such as tool changing mechanisms).

Typical Models:

• V10 Series: V10-1P5P-1A20, V10-1S3S-1A20
• V20 Series: V20F-1P13P-38C8H-22U, V20-1P10P-11D11L
• V20H Series (High-Pressure Upgrade): V20H-1P13P-11D11L (continuous pressure up to 205 bar, suitable for high-precision and high-pressure auxiliary circuits)

1.3 VMQ Series (High-Pressure Heavy-Duty Series)

Designed for harsh operating conditions, this series adopts a 12-vane plug-in design with low noise and high durability, which is suitable for large-scale heavy-duty machining centers and high-pressure hydraulic systems (such as heavy-duty cutting feed mechanisms).

Typical Models:

• VMQ125(T): VMQ125-010-1A20, VMQ125-090-1A20
• VMQ135(T): VMQ135-090-1A20, VMQ135-158-1A20
• VMQ145(T): VMQ145-140-1A20, VMQ145-215-1A20

2. Double/Triple Vane Pump Series (Suitable for Multi-Circuit Hydraulic Systems of Machining Centers)

This series integrates two or three single pumps into one, with compact structure, which can provide independent oil supply for multiple hydraulic circuits of machining centers (such as spindle clamping + feed drive + tool changing), reducing installation space.

2.1 V Series Double Pumps

Combined by different V-series single pumps, it has flexible combination and stable flow superposition, which is suitable for medium and large machining centers with multi-circuit requirements.

Typical Models:

• 2520V Series: 2520VQ17A51AB22R (25V + 20V combination)
• 3525V Series: 3525V38A1711DC22R (35V + 25V combination)
• 45 Series Combination: 4525V45A121AA22R (45V + 25V), 4535V42A301AA22R (45V + 35V)

2.2 VMQ Series Double/Triple Pumps

Based on VMQ series single pumps, it is suitable for heavy-duty machining centers with high-pressure and multi-circuit requirements, featuring high pressure resistance and long service life.

Typical Models:

• VMQ2 Double Pumps: VMQ2 2525S, VMQ2 3525S, VMQ2 4535S
• VMQ3 Triple Pumps: VMQ3 352525S, VMQ3 453525S

2.3 VQ Series Double Pumps

It is a fixed displacement balanced vane pump with interchangeable cartridges, suitable for machining centers that require easy maintenance and multi-circuit oil supply.

Typical Models:

• 2520VQ Series: 2520VQ17A51AB22R
• 3525VQ Series: 3525VQ38A1711DC22R
• 4525VQ Series: 4525VQ45A121AA22R

Note: All models listed above are applicable to machining center hydraulic systems. The specific model selection should be determined according to the working pressure, flow rate and circuit requirements of the machining center.
