T6DC-050-010-1R00-C1 Denison Double Vane Pump 240 bar

Product Overview

The T6CC and T6DC Series, manufactured by Parker Denison, are renowned fixed-displacement double vane pump product lines celebrated for their high-pressure capability, wide speed range, and compact design. The T6 Series encompasses three housing sizes—C, D, and E—with C-frame displacement ranging from 10.8 to 100 ml/r and D-frame displacement ranging from 47.6 to 158 ml/r.

The T6CC/T6DC Series features a balanced-type fixed-displacement design, with fully balanced radial hydraulic forces ensuring long bearing life and smooth operation. The series utilizes Denison’s patented pin-vane (double-lip) technology, delivering higher operating pressure and greater flow within the same housing size. The double pump configuration integrates two independent pumping sections into a single housing driven by one shaft, simultaneously powering two independent hydraulic circuits.

Our products are manufactured to be 100% interchangeable with Parker Denison original specifications—a true “drop-in” replacement solution. Every unit undergoes 100% full-load and flow-matching testing under simulated operating conditions before shipment, ensuring volumetric efficiency, flow rate, and noise performance meet or exceed original specifications at rated pressure.

Key Technical Advantages

1. Pin-Vane (Double-Lip) Patent Technology – Exceptional Contamination Resistance
The Denison T6 Series features a unique pin-vane (double-lip) structure design. Outlet pressure is continuously applied only to the pin, which provides a steady, light force against the vane. The top and bottom areas of the vane are subject to the same pressure (either inlet or outlet pressure, depending on the vane’s location during rotor rotation). This design minimizes noise levels and improves volumetric efficiency while providing exceptional contamination resistance.

2. Balanced-Type Design – Extended Bearing Life
The T6CC/T6DC Series employs a balanced-type hydraulic design, where radial hydraulic forces are fully balanced, eliminating radial loads on the rotor. This dramatically reduces bearing stress, significantly extending bearing life.

3. Ultra-High Pressure Capability in a Compact Envelope
The T6 Series achieves operating pressures up to 275–300 bar within a compact housing size. High-pressure capability allows the use of smaller actuators and lines, reducing overall system cost and installation footprint.

4. Wide Speed Range and Cold-Start Capability
The T6 Series supports a wide speed range of 600–2800 r/min. It operates reliably even at low speeds (600 rpm), low pressure, and high viscosity (860 cSt), adapting to cold-start conditions with low power consumption and no risk of seizing. The overall T7/T67/T6 Series speed range extends from 600 to 3600 rpm.

5. Cartridge Design for Rapid Maintenance
The T6 Series features cartridge-type construction, allowing individual pump cartridges (cam ring, rotor, vanes, pressure plates, port plates) to be replaced quickly and independently. On-site repairs or displacement changes can be completed in minutes without removing the entire pump from the system. Pump rotation can also be easily changed by repositioning the cam ring on the port plate dowel pin hole.

6. Exceptionally Low-Noise Operation
The T6 Series employs a 12-vane system and optimized cam ring profile, significantly reducing pressure ripple and operational noise. The wide speed range combined with large-displacement cartridges enables lowest noise operation within the smallest operating envelope. Pressure ripple is as low as ±2 bar, reducing piping noise and protecting other components in the circuit.

7. 100% Drop-In Interchangeability – Zero Retrofit Cost
Manufactured to exact Parker Denison original specifications—mounting dimensions, port locations, and shaft configurations are identical to the original. Fully compliant with SAE J744c 2-Bolt and ISO 3019-1 standards. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• T6CC Series: Double C-housing combination (small + small). Front pump cam code 020 → 63.8 ml/r displacement; rear pump cam code 005 → 15.9 ml/r displacement.

• T6DC Series: D-housing + C-housing combination (medium + small). Front pump cam code 050 → 158 ml/r displacement; rear pump cam code 010 → 34 ml/r, or 025 → 79 ml/r displacement.

• Cam Code to Displacement Reference: T6C housing: 003=10.8, 005=15.9, 010=34.1, 020=63.8, 025=79.5, 031=100 ml/r; T6D housing: 014=47.6, 020=63.8, 025=79.5, 031=100, 035=110.3, 038=120.3, 042=136, 045=145.7, 050=158 ml/r.

• Seal Suffix Codes: C1/B1 = NBR standard seals for mineral oils; phosphate esters/water glycols require special seal models.

2. Installation Precautions

• Verify pump rotation direction matches system requirements—R denotes clockwise (viewed from shaft end).

• SAE B shaft (T6CC) and SAE C shaft (T6DC) have different dimensions; confirm coupling compatibility.

• Suction piping should be as short as possible, minimizing unnecessary restrictions such as elbows.

• The pump housing must not bear piping loads; suction and discharge lines must have independent supports.

• Coupling selection should minimize pump shaft load (weight, misalignment).

3. Pre-Startup Checklist

• Before startup, verify the reservoir and circuit are clean and free of dirt and debris.

• Confirm fluid type, viscosity, and temperature meet requirements.

• Check pump inlet conditions meet application requirements.

• Prime the pump by filling the housing with oil before first startup to prevent dry running.

4. Fluid Management

• ISO VG32, VG46, or VG68 anti-wear hydraulic oil is recommended.

• The T6 Series accommodates a wide viscosity range (860 cSt to 10 cSt), allowing cold starts and high-temperature operation.

• Fluid cleanliness should be maintained at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• Regularly check oil temperature to ensure it does not exceed 80°C.

5. Scheduled Maintenance

• Replace hydraulic oil and filters every 2000 operating hours or annually.

• The T6CC/T6DC Series features cartridge-type construction—cartridges (cam ring, rotor, vanes, plates) can be replaced independently.

• Cartridge replacement can be completed in minutes without removing the entire pump.

• Mounting bolts and flange connections may loosen due to vibration; inspect and tighten periodically.

• If flow drops or pressure becomes unstable, first inspect cartridge wear—replacing the cartridge kit restores performance.
