T6CC-003-017-1R01-C100 Parker Denison Double Vane Pump

Product Overview

The T6CC-003-017-1R01-C100 is a Parker Denison T6CC industrial fixed-displacement double vane pump designed for hydraulic systems that require stable flow delivery, high-pressure capability and flexible dual-circuit operation.

Parker’s official T7/T67/T6 industrial vane-pump documentation identifies these products as fixed-displacement vane pumps available in single, double and triple configurations. The design is intended for high/low pressure circuits, where different cartridges can be combined to provide lower flow at higher pressure and higher flow at lower pressure. Parker also highlights wide speed capability, improved efficiency, low noise, mounting flexibility and cartridge-based servicing.

For the exact model T6CC-003-017-1R01-C100, Parker’s ordering code defines:

• T6CC: T6CC double-pump series, SAE B / J744 two-bolt mounting
• 003: P1 cartridge, 10.8 mL/rev
• 017: P2 cartridge, 58.3 mL/rev
• 1: Keyed shaft, non-SAE
• R: Clockwise rotation, viewed from the shaft end
• 01: Modification code
• C: Design letter
• 1: S1 BUNA-N seal class
• 00: Standard porting combination

The other model supplied, T6CC-017-006-1R02-C111, uses 58.3 mL/rev for P1 and 21.3 mL/rev for P2. Its R rotation code, C design letter and S1 seal class are consistent with the official T6CC coding system, while modification code 02 and porting combination 11 should be verified against the corresponding Parker configuration drawings rather than inferred.

For replacement applications, the complete part number should be matched—not simply the T6CC series. Displacement, shaft configuration, rotation, porting, seal class and mounting configuration should all be verified before installation. Our replacement units can also undergo 100% simulated operating-condition testing to verify pressure build-up, dual-section flow behavior, leakage condition, abnormal noise and mechanical operation.

Engineering Note: A double vane pump should not be treated as simply one larger single pump. P1 and P2 are separate cartridges and their flow, pressure, input power and leakage behavior must be evaluated independently. Parker specifies that total leakage and hydromechanical power loss for double pumps are the sum of the respective section losses under their individual operating conditions.

Key Technical Advantages

1. Dual-Cartridge Architecture for High/Low Pressure Circuits

Parker states that combining different cartridges in double and triple pumps allows low flow at high pressure and high flow at lower pressure, providing a practical method for optimizing hydraulic-circuit design.

For T6CC-003-017-1R01-C100, the large difference between the P1 and P2 displacements—10.8 versus 58.3 mL/rev—makes the configuration well suited to systems requiring different flow demands from two hydraulic sections.

2. Balanced Vane Technology

The Denison T6 design uses a balanced vane architecture that reduces hydraulic imbalance within the rotating group. Parker identifies improved efficiency and low-noise operation among the key characteristics of the T6/T67/T7 product family.

3. Cartridge-Based Serviceability

The Parker maintenance documentation identifies the housing, cartridge, shaft assembly, pressure and rear port plates, rotor, vanes, cam ring, pins and seals as service components. The documentation also provides dedicated procedures for cartridge removal, conversion and reassembly.

This configuration can reduce maintenance downtime because service can focus on the affected cartridge rather than automatically replacing the entire double-pump assembly.

4. Strong Flow Differentiation Between P1 and P2

The T6CC-003-017 combination provides:

P1 = 10.8 mL/rev
P2 = 58.3 mL/rev

At 1800 r/min, the theoretical flows are approximately:

• P1: 19.44 L/min
• P2: 104.94 L/min
• Combined theoretical flow: 124.38 L/min

These are calculated theoretical values based on Parker’s published geometric displacement. Actual delivered flow depends on volumetric efficiency, pressure, viscosity and operating speed.

5. Established Industrial Mounting Standards

T6CC pumps use SAE J744c / ISO 3019-1 SAE B mounting. Parker’s catalog specifies an approximate T6CC double-pump mass of 26 kg and a corresponding moment of inertia, while also providing standardized SAE hydraulic connection configurations.

This standardized interface is valuable for OEM integration and aftermarket replacement projects.

6. Low-Noise and Low-Pulsation Design Philosophy

Parker identifies low noise levels as a major characteristic of the T6/T67/T7 industrial vane-pump family and describes low ripple-pressure behavior as part of the product design concept. Actual acoustic performance, however, remains dependent on suction conditions, coupling alignment, pipe support, fluid condition and machine structure.

Application Areas

Parker’s industrial vane-pump documentation identifies applications including:

• Injection molding machines
• Presses
• Machine tools
• Hydraulic power units
• Industrial automation equipment
• Lubrication systems
• Metalworking machinery
• High/low pressure hydraulic circuits
• Machines requiring rapid hydraulic-cycle changes

The double-pump configuration is particularly useful when a machine requires two separate flow sources or a combination of high-flow and high-pressure operating stages. Parker specifically describes this architecture as a way to optimize circuit design.

For construction and mining equipment, the pump may also serve as an auxiliary hydraulic power source, but final selection must be based on the actual continuous pressure, intermittent load, flow, speed, drive power and mounting configuration.

Expert Maintenance Tips

1. Evaluate P1 and P2 Independently

Do not select the pump simply on the basis of a generic “T6CC 275 bar” rating.

For T6CC-003-017-1R01-C100:

• P1 = 10.8 mL/rev
• P2 = 58.3 mL/rev

Each cartridge should be checked separately for flow, pressure, power input and leakage. Parker’s documentation explicitly requires double-pump leakage and hydromechanical losses to be considered section by section.

2. Verify Rotation Before Startup

R = clockwise rotation, viewed from the shaft end.

Parker’s service manual specifically instructs users to verify pump rotation against the electric motor or engine rotation before commissioning.

3. Protect the Suction Circuit

Parker recommends keeping suction and return lines separated in the reservoir and submerged below the oil level to minimize aeration and vortex formation. Short, straight suction lines are preferred, and Parker recommends an inlet velocity of approximately 0.5–1.9 m/s.

4. Avoid Unnecessary Inlet Strainers

Parker does not recommend inlet strainers. When an inlet strainer is unavoidable, the published recommendation is no finer than 100 mesh / 149 μm. Filtration should otherwise be designed around the cleanliness requirements of the complete hydraulic circuit.

5. Bleed Air Before Full-Pressure Operation

Before startup, use clean hydraulic fluid and ensure the circuit and pump are properly air-bled. Parker notes that the pump should prime within a few seconds under normal conditions. Persistent noise or failure to prime requires troubleshooting before high-pressure operation.

6. Maintain Proper Coupling Alignment

Parker recommends coaxial drive arrangements and warns against unnecessary axial or side loading of the pump shaft. For supported spline connections, Parker specifies tight alignment limits and recommends appropriate spline lubrication.

7. Match the Seal Class to the Fluid

The S1 seal class in these models is BUNA-N, specified for mineral-oil service with a maximum standard shaft-seal pressure of 0.7 bar. Alternative fire-resistant or specialty fluids require verification of the applicable seal class before operation.

8. Avoid Continuous Operation at the Intermittent Limit

For standard anti-wear petroleum-based hydraulic fluid, Parker publishes 275 bar intermittent / 240 bar continuous for the applicable T6CC cartridge range. Long-term operation near the upper limit should also consider speed, inlet pressure, viscosity, temperature and input power rather than pressure alone.
