Key Technical Advantages

1. Advanced Intra-Vane Technology
The 45V series employs Vickers’ patented Intra-Vane design, where each primary vane contains a secondary “intra-vane” that uses centrifugal force and hydraulic pressure to extend the primary vane, ensuring intimate contact with the cam ring surface. This significantly reduces contact stress between vanes and the cam ring, minimizing friction and wear while extending pump service life.

2. Drop-in Interchangeability
Manufactured to exacting Vickers 45V series OEM standards, our pump is fully interchangeable with the original equipment in mounting dimensions, SAE C 2-bolt flange interface, port configurations, and performance characteristics. No modifications to existing hydraulic piping or mounting brackets are required.

3. 100% Simulated Operating Condition Testing
Every pump undergoes comprehensive factory performance testing under simulated operating conditions, covering rated pressure, peak pressure, flow characteristics, and temperature rise. This ensures the product is ready for full-load operation immediately upon installation, eliminating early failure risks.

4. 282/283 Series Low-Noise Design
Models with the 282/283 suffix incorporate noise reduction optimization entirely within the cartridge kit. All sound reduction is achieved within the cartridge assembly, delivering quieter operation while maintaining the same reliability, operating characteristics, and service advantages as previous models. Volumetric efficiency exceeds 90%.

5. Cartridge Modular Design for Easy Maintenance
The pump features a cartridge (pumping cartridge) modular design with all internal components assembled as a complete unit secured by screws. The cartridge can be replaced quickly without disassembling the entire pump body, dramatically reducing service time and downtime.

6. High-Quality Cast Iron Housing and Precision Manufacturing
The pump body is manufactured from high-strength cast iron with precision CNC machining and heat treatment processes. The SAE C 2-bolt flange mounting ensures accurate alignment with the power source, reducing the risk of uneven bearing loading.

Application Areas

• Injection Molding Machines — Stable flow and pressure output for precision molding

• Hydraulic Presses — Power source for various oil presses and hydraulic presses

• Metal Cutting Machine Tools — Hydraulic systems for machining centers and CNC machines

• Metallurgical Equipment — Hydraulic systems for rolling mills and continuous casting equipment

• Oil and Gas Equipment — Hydraulic power units for demanding environments

• Dump Trucks and Wheel Loaders — On-board hydraulic systems

• Industrial Automation Equipment — Hydraulic actuators for automated production lines

Expert Maintenance Tips

1. Installation Guidelines

• Verify pump rotation direction matches the drive motor (R-type = clockwise, viewed from shaft end) before installation

• Mounting flange is SAE C 2-bolt standard; ensure mounting bolt torque meets specifications

• Inlet port: 3″ SAE 4-bolt flange; outlet port: 1.5″ SAE 4-bolt flange

• Ensure coupling concentricity deviation does not exceed 0.05 mm

• Minimum start-up speed is 600 r/min; ensure this speed is achieved during initial start

2. Hydraulic Fluid Selection and Contamination Control

• Recommended fluid: ISO VG 46 anti-wear hydraulic oil

• For phosphate ester or water-glycol fluids, specify F3 prefix models (Viton fluororubber seals required)

• System cleanliness should be maintained at NAS 1638 Class 9 or better; install return line filtration (≤ 10 μm absolute)

3. Start-up and Operation

• Pre-lubricate the pump by filling the drain port with clean hydraulic fluid before first start

• Perform 2-3 low-speed jogging cycles under no-load conditions to purge air from the system before applying load

• The noise reduction performance of 282/283 series pumps depends on precise fit within the cartridge kit; using inferior hydraulic fluid will directly impact noise reduction capability

4. Scheduled Maintenance

• Replace hydraulic fluid and filters every 2,000 operating hours or annually, whichever comes first

• Regularly monitor pump housing temperature (normal temperature rise ≤ 40°C; maximum housing temperature ≤ 80°C)

• Investigate unusual noise or pressure fluctuations promptly; inspect cartridge kit components for wear

• Note: Individual cartridge parts from different design models are NOT interchangeable; the complete cartridge kit must be replaced as a whole

5. Spare Parts Recommendation

• Stock cartridge kit repair assemblies for quick on-site service without pump body disassembly

• Maintain seal kit inventory, especially for systems using specialty fluids such as phosphate esters
