T6C-022-1R00-B1 Denison Fixed Vane Pump 70.3 ml/r 275 bar

Product Overview

The T6C, T6D, and T6E Series, manufactured by Parker Denison, are renowned fixed-displacement single 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—each accommodating cartridge kits with different displacements. T6C Series displacement ranges from 10.8 to 100.0 ml/r, T6D Series from 47.6 to 158.0 ml/r, and T6E Series from 132.3 to 227.1 ml/r.

The T6 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 only to the pin, providing a steady, light force against the vane, while the top and bottom areas of the vane are subject to the same pressure. This design minimizes noise levels and improves volumetric efficiency, delivering higher operating pressure and greater flow within the same housing size.

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 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 T6 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 T6 Series achieves operating pressures up to 275–280 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. Cartridge Design for Rapid Maintenance
The T6 Series features cartridge-type construction, allowing individual pump cartridges (cam ring, rotor, vanes, plates) to be replaced quickly and independently. The cartridge is independent of the shaft, enabling flow capacity changes and field servicing without removing the pump from its mounting. The cartridge design also allows easy changes of flow capacity.

5. Through-Drive Capability for Flexible System Expansion
The T6 Series supports multiple pump series connections. Double pumps offer multiple mounting configuration options—a single power source can drive multiple hydraulic pumps, greatly simplifying complex hydraulic system design. The T6 Series is available in single, double, and triple configurations.

6. 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). The wide viscosity range permits cold starts and hot operation.

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

• T6C Series Housing: Displacement range 10.8–100.0 ml/r, available cartridge codes 003, 005, 006, 008, 010, 012, 014, 017, 020, 022, 025, 028, 031.

• T6D Series Housing: Displacement range 47.6–158.0 ml/r, available cartridge codes 014, 017, 020, 024, 028, 031, 035, 038, 042, 045, 050.

• T6E Series Housing: Displacement range 132.3–227.1 ml/r.

• In model code “T6C-022-1R00-B1”: 022 = displacement code (70.3 ml/r), 1 = SAE B keyed shaft, R = clockwise rotation, 00 = port position (opposite), B1 = NBR seal.

• Seal Codes: B1 = NBR standard seal for mineral oils; S4 or S5 for fire-resistant fluids.

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—T6C uses SAE B shaft (Ø22.22 mm), T6D uses SAE C shaft (Ø31.75 mm).

• 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.

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

3. Pre-Startup Checklist

• Before startup, verify pump rotation, speed range, pressure, temperature, and fluid quality and viscosity.

• Check pump inlet conditions meet application requirements.

• Verify shaft type meets torque requirements.

• Ensure filtration maintains fluid cleanliness (NAS 9 or higher recommended).

• 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, permitting cold starts and hot operation.

• Compatible fire-resistant fluids include phosphate esters, water glycols, and water-in-oil emulsions.

• 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 T6 Series features cartridge-type construction—cartridges can be replaced independently.

• Cartridge replacement can be completed 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.
