Vickers V Series Vane Pumps
Vickers V Series pumps are fixed-displacement vane pumps for medium-pressure industrial applications, using an industry-first intra-vane cartridge design. Sixteen flow displacements are available across single, double and thru-drive configurations, giving optimum selection and single-source capability for a complete range of flow and pressure requirements.
A twelve-vane system provides low-amplitude flow pulsations for low system noise, with sound levels as low as 62 dB(A) and volumetric efficiencies of more than 90%. Hydraulic balancing is designed to prevent internally induced radial shaft and bearing loads, supporting long service life. The cartridge kit design is independent of the drive shaft, allowing flow capacity to be changed or the pump serviced without removing it from its mounting.
Double pumps and thru-drive arrangements save installation space and cost by eliminating double-shaft-extension electric motors, or by reducing the number of motors and drive couplings needed. Thru-drive models allow fixed and variable displacement pumps to be run from a single input drive. Inlet and outlet ports can be oriented in four positions relative to each other, and mounting is available in SAE and metric ISO pilot flange options, with an optional bolt-on foot mounting bracket.
V Series pumps run on standard anti-wear hydraulic oil and can also be specified with fluorocarbon seals for use with phosphate ester, water glycol or water-in-oil emulsion fluids; see Fluid Compatibility below.
Key Specifications
| Specification | Detail |
| Technology | Balanced vane, intra-vane cartridge design, fixed displacement |
| Configurations | Single, double, and thru-drive (single pump with a rear mounting pad for a second pump) |
| Displacement range | 7 to 193 cm³/rev (0.43 to 11.75 in³/rev) across sixteen flow displacements |
| Rated speed | 1800 rev/min (all models, using anti-wear fluid) |
| Minimum speed | 600 rev/min (all models and fluid combinations) |
| Sound level | As low as 62 dB(A); typically 62 to 71 dB(A) at 138 bar depending on model and speed, per NFPA T3.970.12; double pumps run 1 to 3 dB(A) higher when both sections are pressurised |
| Volumetric efficiency | Greater than 90% |
| Inlet pressure | Minimum -0.17 bar (5 in. Hg) for anti-wear oil, or -0.10 bar (3 in. Hg) for water-containing fluids and phosphate esters; maximum 1.4 bar (20 psi) all fluids |
| Case drain | None; the pump is drained internally into its inlet. System pressure at the pump inlet connection may not exceed 1.4 bar (20 psi) |
| Hydraulic fluid | Anti-wear industrial hydraulic oil or automotive crankcase oil (SC, SD, SE or SF), viscosity 32 to 68 cSt at 40°C (140°F); water-in-oil emulsions and phosphate ester fire-resistant fluids can also be used, see Fluid Compatibility below |
| Fluid temperature | Minimum 49°C (120°F); maximum 65°C (150°F) at rated speed and pressure; should not exceed 99°C (210°F) at any time, as cartridge kit and elastomer life will decrease |
| Mounting | SAE 4-bolt flange as standard, with SAE (ISO 3019/1) or metric (ISO 3019/2) pilot flange options; a bolt-on foot mounting bracket is also available |
| Ports | SAE 4-bolt flange, inch or metric thread; inlet and outlet can be oriented in four positions relative to each other on single pumps |
| Seals | Standard seals as supplied; fluorocarbon (Viton) seals available for phosphate ester, water glycol and water-in-oil emulsion fluids by adding the F3 prefix to the model code |
Single Pumps

Double Pumps
Double pumps combine a shaft-end and cover-end pump in a single housing. Where both sections are pressurised together, combined shaft torque must be checked against the shaft torque rating; see the manufacturer technical document.
| Model | Shaft-end displacement cm³/rev (in³/rev) | Cover-end displacement cm³/rev (in³/rev) | Max. continuous pressure, bar (psi) |
| 2520V | 33 to 67 (2.01 to 4.13) | 7 to 45 (0.43 to 2.78) | 172 (2500) shaft / 207 (3000) cover |
| 2525V | 33 to 67 (2.01 to 4.13) | 33 to 67 (2.01 to 4.13) | 172 (2500) both sections |

Thru-Drive Pumps
Thru-drive pumps provide a rear mounting pad (SAE A, B or C, or a “BP” adapter for mounting a PVE12/19/21 piston pump) for a second pump to be driven from the same shaft.

Fluid Compatibility
V Series pumps are rated for use with anti-wear hydraulic oil, phosphate ester fire-resistant fluids, water-in-oil emulsions, and water glycol fluid, with reduced speed and, in some cases, reduced pressure depending on fluid type:
- Anti-wear oil or phosphate ester: full rated pressure (up to 207 bar on 20V, up to 172 bar on 25V/35V/45V, depending on displacement code); maximum speed 1800 rev/min
- Water-in-oil emulsion: maximum continuous pressure 69 bar (1000 psi), all models; maximum speed 1200 rev/min
- Water glycol: maximum continuous pressure up to 159 bar (2300 psi), varies by displacement code; maximum speed 1500 rev/min
A transient (peak) pressure 10% over the continuous rating is allowed for 0.5 seconds or less. Recommended fluid cleanliness for fixed vane pumps is ISO 4406 20/18/15 below 70 bar, 19/17/14 between 70 and 207 bar, and 18/16/13 above 207 bar.
