T6DC-035-031-1R00-B1 Denison Double Vane Pump 211 ml/r 210 bar

Product Overview

The T6DC Series, manufactured by Parker Denison, is a renowned fixed-displacement double vane pump integrating a T6D housing (Section 1/front) and a T6C housing (Section 2/rear) into a single housing driven by a common shaft, simultaneously powering two independent hydraulic circuits.

The T6DC Series features a balanced-type fixed-displacement design, fully balancing radial hydraulic forces for long bearing life and smooth operation. The series utilizes Denison’s patented pin-vane (double-lip) technology—outlet pressure is continuously applied to the pin, providing a steady, light force against the vane; the top and bottom areas of the vane are subject to the same pressure. This design minimizes noise levels and improves volumetric efficiency. The T6DC Series achieves rated operating pressures up to 240 bar and speeds up to 2200 r/min.

The T6DC-035-031-1R00-B1 features 035 (111 ml/r) and 031 (100 ml/r) cartridges, with a total displacement of 211 ml/r. The T6DC-045-005-1R00-C100 features 045 (145 ml/r) and 005 (18 ml/r) cartridges, with a total displacement of approximately 163 ml/r. The T6DC-050-010-1R00-C1 features 050 (158 ml/r) and 010 (34 ml/r) cartridges, with a total displacement of 192 ml/r.

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 T6DC Series features a unique pin-vane (double-lip) structure design. Outlet pressure is continuously applied to the pin, providing 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 T6DC Series employs a balanced-type hydraulic design, fully balancing radial hydraulic forces and eliminating radial loads on the rotor. This dramatically reduces bearing stress, significantly extending bearing life and ensuring long-term stable operation under high-pressure conditions.

3. Ultra-High Pressure Capability in a Compact Envelope
The T6DC Series achieves operating pressures up to 240–275 bar within a compact housing size. High-pressure capability allows the use of smaller actuators and lines, reducing overall system cost and installation footprint. The T6 Series operates reliably at low speeds (600 rpm) and across a wide viscosity range, permitting cold starts with low power consumption.

4. Cartridge Design for Rapid Maintenance
The T6DC Series features cartridge-type construction, allowing individual pump cartridges (cam ring, rotor, vanes, 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.

5. Double Pump Design – Single Power Source, Dual-Circuit Independent Control
The T6DC Series integrates T6D and T6C pumping sections into one housing driven by a single shaft. This design allows a single power source to simultaneously serve two independent hydraulic circuits, or provide greater total flow through combined delivery. The double pump configuration offers more compact installation and lower cost.

6. Wide Speed Range and Cold-Start Capability
The T6DC Series supports a wide speed range of 600–2200 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.

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. Mounting complies with SAE J744c 2-bolt flange standards. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• T6D Available Cartridge Codes: 014(47.6), 017(58.2), 020(66.0), 024(79.1), 028(89.7), 031(98.3), 035(111.0), 038(120.7), 042(136.0), 045(145.0), 050(158.0) ml/r.

• T6C Available Cartridge Codes: 003(10.8), 005(18.0), 006(21.3), 008(26.7), 010(34.1), 012(37.1), 014(46.0), 017(58.3), 020(63.8), 022(70.3), 025(79.3), 028(88.8), 031(100.0) ml/r.

• Model Code Interpretation: Taking T6DC-035-031-1R00-B1 as an example—T6DC = Series (D+C double), 035 = Section 1 cartridge code (111 ml/r), 031 = Section 2 cartridge code (100 ml/r), 1 = SAE C straight/keyed shaft, R = Clockwise rotation, 00 = Port position, B1 = NBR seal.

2. Installation Precautions

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

• Confirm shaft type matches—T6DC Series Code 1 is SAE C straight/keyed shaft.

• T6DC Series uses SAE C 2-Bolt Flange mounting (J744c).

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

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

3. Pre-Startup Checklist

• Verify oil level in the reservoir is adequate and fluid type is correct (ISO VG32, VG46, or VG68 anti-wear hydraulic oil recommended).

• Confirm all piping connections are secure with no leakage.

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

• Confirm both discharge ports are correctly connected to their respective hydraulic circuits.

4. Fluid Management

• High-quality anti-wear hydraulic oil is recommended; maintain fluid cleanliness at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• T6DC Series is compatible with mineral oils, water glycols, and phosphate esters.

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

• 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.

• T6DC Series features cartridge-type construction—cartridges 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.
