Double Vane Pump

Double Hydraulic Vane Pump . DENISON T6DC Series 47.6CC-190.5CC

Overview of DENISON T6DC Double Hydraulic Vane Pump

The DENISON T6DC Double Hydraulic Vane Pump represents the industry benchmark for high-pressure, fixed-displacement vane technology, solving dual-circuit integration challenges without the complexity and bulk of tandem gearboxes. By packaging two independently functioning cam-ring cartridge assemblies inside a single monolithic cast-iron casing, the T6DC allows hydraulic system designers to supply two completely isolated hydraulic circuits—such as a high-volume low-pressure circuit paired with a high-pressure low-volume circuit—from a single motor or diesel engine power take-off (PTO).

Built with spheroidal ductile cast iron and precision-ground alloy steel components, the T6DC structure delivers exceptional mechanical damping, preventing resonance vibrations and pressure ripples across wide operating frequencies. Internally, Parker Denison's proprietary pin-vane double-lip design eliminates excessive vane-tip-to-cam-ring contact loading. Fluid pressure channeled under the vanes balances the hydraulic loading against the cam contour, drastically cutting friction and preventing micro-galling under operating pressures up to 240 bar. High-flow suction corridors combined with optimized dual-discharge port plates ensure smooth laminar fluid intake, suppressing cavitation even when using higher-viscosity fluids during cold start-ups. Floating bi-metallic side plates maintain precise axial clearances automatically, ensuring volumetric efficiency remains above 94% across extended duty cycles.

5. Advantages of DENISON T6DC Double Hydraulic Vane Pump

Parker Denison Pin-Vane Technology. The patented pin-vane mechanism dynamically balances the hydraulic loading of the vane against the cam contour, minimizing vane tip contact force, eliminating ring chattering, and sustaining high volumetric efficiency over thousands of hours.

Dual-Circuit Independent Power Delivery. Integrates two independently operating displacement sections (P1 and P2) within a single compact body, eliminating the need for bulky two-pump split gearboxes and saving crucial installation space in mobile chassis.

Ultra-Low Acoustic Noise Levels. Pressure-balanced design and smooth port plate timing grooves drastically suppress flow pulsation, providing whisper-quiet operation that complies with indoor factory and mobile vehicle noise standards.

Drop-In Modular Cartridge Kit Architecture. Both D-size (P1) and C-size (P2) assemblies are engineered as modular cartridge kits. Flow capacity can be easily converted or overhauled on-site without uncoupling the pump body from the machine piping.

High Pressure & Thermal Stability. Robust spheroidal graphite cast-iron construction resists internal pressure deflection up to 275 bar peak, maintaining dimensional stability across extreme temperature fluctuations from -18 °C to +100 °C.

Exceptional Contamination Resistance. The double-lip vane configuration wipes the cam ring clean during rotation, preventing abrasive particle entrapment and providing superior contamination tolerance compared to standard axial piston or gear pumps.
