T6CCB14B121R03C111 Parker Double Vane Pump 275Bar

Model Number	T6CCB14B121R03C111

Product Description

Product Overview

The T6CCB14B121R03C111 is a high-performance, industrial-grade double hydraulic vane pump manufactured to rigorous engineering standards, offering 100% direct interchangeability with the Parker Denison T6 series. Engineered with a classic pin-vane design, this pump is tailored for high-pressure, high-flow, and heavy-duty continuous industrial operations. Prior to dispatch, every T6CC double pump undergoes 100% full-load simulated operating condition testing. This ensures that its volumetric efficiency, pressure pulsation resistance, and fatigue life match or exceed original OEM specifications. It serves as the ultimate drop-in replacement solution during major equipment overhauls, significantly reducing overall procurement costs and lead times.

Key Technical Advantages

Advanced Pin-Vane Technology: The unique pin-vane architecture uses hydrostatic self-compensation to balance the contact stress between the vane tips and the cam ring. This significantly mitigates wear, enabling the pump to maintain a volumetric efficiency of over 94% even at peak pressures of 275 bar.
100% True Interchangeability: From the SAE standard mounting flange and shaft dimensions to the port center distances, every physical spec mirrors the OEM Parker Denison pump perfectly. Customers enjoy a true plug-and-play replacement without modifying any piping or base brackets.
Superior Noise and Pulsation Reduction: The cam ring features an asymmetrical transition profile, combined with precision-machined metering notches on the side plates. This design drastically minimizes hydraulic shock during flow reversal, keeping operational noise within a low 70-75 dB(A) even under full load.
Hydrostatically Balanced for Long Life: The internal cartridge kit features a fully balanced radial hydraulic pressure structure. This completely eliminates hydraulic radial loads acting on the drive shaft and bearings, maximizing design fatigue life and reducing unscheduled downtime.

Application Areas This T6CC double vane pump is the ideal power source for heavy-duty machinery requiring multiple independent fluid sources or dual-speed (High-Low) circuits:

Plastic Injection & Die-Casting Machines: Delivering highly efficient, pulsation-free hydraulic power for clamping and injection cylinders.
Mobile Machinery & Heavy Hoisting: Essential for marine winches, steering systems, and main lifting circuits in construction equipment.
Material Forming Presses: Perfectly matches the dual-speed (rapid approach & feed phase) requirements of hydraulic shears and press brakes.
Industrial Hydraulic Power Units (HPU): Serving as the core prime mover for large metallurgical equipment and automated production lines.

Expert Maintenance Tips

Proper Start-up Bleeding: Before the initial start-up or after a rebuild, you must bleed all trapped air from the highest point in the system. Jog the electric motor 3 to 5 times (no longer than 2 seconds each) to prime the pump and ensure internal components are lubricated. Dry running is strictly prohibited.
Strict Fluid Cleanliness Control: The ultra-high volumetric efficiency relies on micron-level internal clearances. We recommend a return line filtration rating of at least 10μm absolute. System fluid cleanliness must be maintained at ISO 4406 Class 18/16/13 (or NAS 1638 Class 8) or better.
Cold Start Viscosity Limits: During winter or in low-temperature environments, if the fluid viscosity exceeds 800 cSt, do not apply full load at high speeds. Run the pump unloaded at low RPMs until the oil temperature reaches above 20°C before engaging the system load.
