Product Description Eaton Vickers VQ and VQH series pumps are specifically designed for higher pressure and higher speed mobile requirements. Vickers VQ series pumps are designed for medium pressure mobile applications. Vickers VQH series pumps are the higher pressure and higher performance version.They feature the same intra-vane cartridge design as the V Series pumps and provide long operating life, outstanding volumetric efficiency and excellent serviceability. Typical applications include: wheel loaders, lift trucks, refuse vehicles and aerial booms.Eaton Vickers VQ and VQH pumps offer:Displacements from 18 cc/rev to 193 cc/rev.Maximum continuous pressures up to 241 bar (3,500 psi)Rated Speeds up to 2,700 rpm.Features include:10-vane systems;Solid architectures in the same compact size;Many available bearing and valve options;Pressure-balanced, modular design reduces noise, extends life and improves serviceability.The VQH series also provides additional benefits of:Strong ductile iron housing;Improved rotor design to reduce leakage and enhance rotor rigidity;Higher pressure and higher performance capabilities.Eaton Vickers VQ(H) series pumps are available in single and through-drive styles with three frame sizesModel codes are as follows:Single pumps: 20VQ | 25VQ | 35VQ | 45VQDouble pumps: 2520VQ | 3520VQ | 3525VQ | 4520VQ | 4525VQ | 4535VQTriple pumps: 2520VQSV10 | 3520VQSV10 | 3525VQSV10 | 4525VQSV10 | 4535VQSV10Thru-Drive single pumps:Standard bearing: 25VQT | 35VQT | 45VQTHeavy duty bearing: 26VQT | 36VQT | 46VQTThru-Drive double pumps:Standard bearing: 3525VQT | 4525VQTHeavy duty bearing: 3625VQT | 4625VQT standard bearing.Detailed Introduction to the Application Fields of the Vickers VQ Vane PumpThe Vickers VQ Vane Pump is a fixed-displacement vane pump characterized by its compact structure, stable output flow, high volumetric efficiency (especially under high pressure), and reliable operation. These attributes make it well-suited for hydraulic systems that demand consistent, medium-pressure oil supply (up to 21MPa) and low to moderate flow rates. Its detailed application fields in English are categorized as follows: 1. General Industrial MachineryThis is the core application area of the Vickers VQ Vane Pump, where it primarily powers critical hydraulic functions in standard manufacturing and processing equipment:- Machine Tools: Used in hydraulic circuits for lubrication systems (to reduce friction between moving parts like spindles and guide rails), clamping mechanisms (to secure workpieces tightly during machining), and feed drives (to control precise linear/rotary motion of tool heads or worktables in lathes, milling machines, and grinders). Its stable flow ensures consistent machining accuracy and reduces tool wear.- Plastic & Rubber Machinery: Integrated into small to medium-sized plastic injection molding machines (for driving ejector pins, mold-closing units, and material feeding screws) and rubber extruders (to regulate the pressure of rubber material extrusion). The pump's low noise and reliable performance align with the continuous operation needs of these machines.- Textile Machinery: Applied in hydraulic systems of weaving machines (to control the tension of yarns and the movement of heddles) and dyeing equipment (for adjusting the pressure of dye liquor circulation and the lifting of fabric rollers). Its compact size fits the limited installation space in textile production lines. 2. Light Industry EquipmentThe Vickers VQ Vane Pump is widely used in light industry due to its adaptability to low to medium load requirements and its ability to integrate with small hydraulic power units: - Packaging Machinery: Powers hydraulic components in carton sealers (to drive the pressure rollers for tight sealing), filling machines (to control the lifting of filling nozzles and the clamping of containers), and wrapping machines (for adjusting the tension of wrapping films). Its fixed-displacement design ensures uniform packaging pressure, avoiding material damage.- Printing Machinery: Used in offset printing machines (to drive the ink roller adjustment mechanism and paper feeding/clamping systems) and labeling machines (for the precise positioning of labeling heads). The pump's stable flow maintains consistent ink distribution and label alignment, improving printing quality.- Food Processing Machinery: Integrated into hydraulic systems of food cutters (to control the cutting blade's lifting and pressure) and baking equipment (for adjusting the height of oven racks). It meets the industry's requirements for low leakage and clean operation (when paired with food-grade hydraulic oil). 3. Construction & Agricultural Machinery (Auxiliary Circuits)While large construction/agricultural machinery typically uses high-pressure variable-displacement pumps for main drives, the Vickers VQ Vane Pump is often employed in their auxiliary hydraulic circuits due to its cost-effectiveness and reliability:- Construction Machinery: Used in small to medium-sized equipment such as small loaders (for auxiliary functions like bucket tilt fine-tuning and cab lifting) and forklifts (to power the steering assistance system and the small-scale lifting of auxiliary attachments). Its compact structure saves space in the machinery's hydraulic compartment.- Agricultural Machinery: Applied in small tractors (for auxiliary systems like the lifting of light farm tools, e.g., seeders or small plows) and greenhouse equipment (to drive the hydraulic cylinders for opening/closing greenhouse vents and adjusting irrigation sprayers). It adapts well to the variable working environments of agriculture (e.g., moderate dust and temperature fluctuations). 4. Automotive Manufacturing & Automated Production LinesThe Vickers VQ Vane Pump supports the stable operation of hydraulic-driven automation equipment in these fields:- Automotive Manufacturing: Used in auto part stamping machines (to control the auxiliary clamping of metal sheets) and assembly line robots (for small-scale hydraulic actuators, e.g., the gripping of lightweight auto parts like bolts or gaskets). Its low vibration and noise meet the requirements of clean, high-precision automotive production workshops.- Automated Production Lines: Powers hydraulic components in conveyor systems (to adjust the tension of conveyor belts) and material handling equipment (for the lifting and positioning of small workpieces). Its fixed-displacement output ensures synchronized motion of multiple hydraulic actuators in the production line, improving efficiency.Eaton Vickers Double/ Vane Pump SpecificationsShaft End PumpCover End PumpModel Delivery USgpm @ 1200 r/min 7 bar (100 psi)Displ.cm3/r(in3/r)Max.r/minMax.bar (psi)Typical del.
