T6DCM-B38-B14-3L00-C1 Denison Double Vane Pump 240 bar

Product Overview

The T6CC, T6DCM, and T6EDM Series, manufactured by Parker Denison, are renowned fixed-displacement 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. C-Series displacement ranges from 10.8 to 100.0 cm³/rev, D-Series from 47.6 to 158.0 cm³/rev, and E-Series from 132.3 to 227.1 cm³/rev.

The T6DCM combines D-housing and C-housing in a double configuration; T6CC combines two C-housings; T6EDM combines E-housing and D-housing. All T6 Series pumps feature 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. Double/triple pump configurations integrate multiple independent pumping sections into a single housing driven by one shaft, simultaneously powering multiple 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 to the pin, providing a steady, light force against the vane. 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. The balanced design compensates for wear and temperature changes, maintaining good lubrication between rotor and port plate even under high-viscosity or low-temperature conditions.

3. Wide Speed Range and Cold-Start Capability
The T6 Series supports a wide speed range of 400–2800 r/min. It operates reliably even at low speeds (600 rpm). The wide viscosity range of 2000–10 cSt permits cold starts and hot operation.

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 “drop-in” assembly method simplifies modification and repair while minimizing contamination ingress risk. On-site repairs can be completed in minutes without removing the entire pump.

5. Exceptionally Low Noise and Low Pressure Ripple
The T6 Series achieves pressure ripple as low as ±2 bar, significantly reducing piping noise and protecting other components in the circuit. The wide speed range combined with large-displacement cartridges enables lowest noise operation within the smallest envelope.

6. Through-Drive Capability for Flexible System Expansion
The T6 Series supports multiple pump series connections. Double pumps offer 32 mounting configuration options—a single power source can drive multiple hydraulic pumps, greatly simplifying complex hydraulic system design and reducing installation costs.

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 cm³/rev, cartridge codes 003, 005, 006, 008, 010, 012, 014, 017, 020, 022, 025, 028, 031

• T6E Series Housing: Displacement range 132.3–227.1 cm³/rev

• T6DCM Model: D-housing (Section 1) + C-housing (Section 2) double combination

• T6CC Model: C-housing + C-housing double combination

• T6EDM Model: E-housing (Section 1) + D-housing (Section 2) double combination

• Seal 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, L denotes counter-clockwise (viewed from shaft end).

• Confirm shaft type matches—T6DCM 3L00/3R13 uses SAE C splined shaft (14 teeth 12/24DP).

• Mounting complies with SAE J744c 2-bolt flange standards.

• 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.

• 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 (2000–10 cSt), permitting cold starts and hot operation.

• Compatible fire-resistant fluids include phosphate esters, chlorinated hydrocarbons, 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.

• For mobile pumps, “C” and “D” series cartridges are bidirectional—identified by “B” in the model code. To change rotation, simply reposition the cam ring locating pin hole on the port plate.

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

• Pump operating environment should avoid noise, contamination, and vibration sources where possible.
