45VTCS60A-2297DA-23R Vickers Vane Pump | 210 Bar

Product Overview:

Engineering Note: Although the original market title mislabels this as a “Piston” pump, the 45VTCS60A is a classic, high-performance Thru-Drive Vane Pump. Engineered for multi-circuit hydraulic systems requiring high load capacities, the 45VTCS60A-2297DA-23R thru-drive vane pump (representing the 25VT, 35VT, 45VTC, and 25VQ series) features the proven Eaton Vickers Intravane architecture. This design significantly enhances volumetric efficiency and operational lifespan. Its most critical advantage is the standard SAE thru-drive rear mounting interface, which allows for the direct tandem mounting of a secondary hydraulic pump (such as a gear or piston pump) without requiring an additional prime mover. Every pump undergoes 100% full-load simulated testing prior to dispatch. With dimensions and performance metrics that perfectly match original OEM specifications, it offers true drop-in interchangeability, making it an ideal choice for saving space and lowering maintenance costs.

• Recommended Oil Viscosity: 13 – 54 cSt (Optimal operating temp: 40℃ to 60℃)

Key Technical Advantages:

• Space-Saving Thru-Drive Capability: The robust main shaft and integrated rear flange allow users to couple a secondary gear, piston, or vane pump directly to the rear of the main pump. This multi-pump tandem configuration drastically reduces installation space and eliminates the need for extra PTOs or motors.

• High-Pressure Intravane Architecture: The advanced intravane design uses continuous hydraulic pressure to dynamically balance the vanes against the cam ring. This minimizes wear on the vane tips, allowing the pump to maintain continuous high performance at pressures up to 210 bar.

• True OEM Interchangeability: Engineered to precise tolerances, the mounting pilots, flange offsets, and internal cartridge kits are 100% interchangeable with original Vickers 45VT/45VQ models. This enables rapid plug-and-play replacements without modifying existing piping.

• Modular Design & 100% Testing: The independent cartridge kit allows for quick field servicing. Prior to shipment, every unit is subjected to rigorous automated testing under maximum pressure and flow conditions to guarantee zero-defect reliability and no internal leakage.

Application Areas:

• Mobile & Earthmoving Machinery: Pilot and main working circuits in wheel loaders, motor graders, and heavy excavators (often driving a tandem steering pump).

• Injection Molding & Die Casting: Clamping and injection circuits in large-scale plastic machinery requiring multi-circuit high-flow delivery.

• Industrial Press Equipment: Main power units for metal-forming hydraulic presses, shears, and press brakes.

• Marine & Oilfield Systems: Multi-circuit power sources for winch drives, mud pump stations, and heavy deck machinery.

Expert Maintenance Tips:

• Tandem Torque Verification: When utilizing the thru-drive feature, carefully calculate the combined torque of both the front and rear pumps operating at maximum pressure simultaneously. Ensure the total torque does not exceed the maximum allowable torsional limit of the main drive shaft.

• Initial Priming Protocol: Before first startup, completely fill the housings of both the main pump and the secondary rear pump with clean hydraulic fluid. Dry running is strictly prohibited and will cause instantaneous damage to the cam ring and port plates.

• Strict Fluid Cleanliness: Intravane pumps are highly sensitive to particulate contamination. It is highly recommended to install a 10-25 micron return line filter to maintain fluid cleanliness at ISO 4406 18/15/13, ensuring long-term volumetric efficiency and preventing premature wear.
