Denison T67EDCS T67EDC industrial triple hydraulic vane pump

The T67 series is a combination pump — it takes cartridges from Denison's T6 and T7 pump families and stacks them together in one body. The T67 series triple vane pump combines T6 and T7 series cartridges and parts into a single unit. In the case of the T67EDC/T67EDCS specifically, the "E" and "D" designations refer to the cartridge sizes used in the stack, with a "C" cartridge completing the triple combination.

Real-World Applications

Example 1: Plastic Injection Molding

A mid-size injection molding machine typically needs three distinct flow/pressure regimes in a single cycle: fast mold-close at low pressure, high-pressure clamp/hold, and controlled-speed injection. A T67EDC configured with the right cartridge stack lets the machine builder assign one cartridge to each stage, cutting cycle time versus a single fixed-displacement pump sized for peak pressure alone.

Example 2: Die-Casting Machines

Die-casting rigs combine high clamping force with fast shot-sleeve movement, often using fire-resistant hydraulic fluid because of the proximity to molten aluminum or zinc. The T67 series' rated compatibility with water-glycol and water-in-oil emulsion fluids makes it a common OEM choice on this equipment, since the pump doesn't need to be swapped out for a different fluid-compatible design.

Example 3: Hydraulic Presses and Forging Equipment

Multi-stage forging presses use a fast-approach, slow-press, high-tonnage cycle almost identical in shape to injection molding. Triple vane pumps like the T67EDCS (on SAE-flanged American-built press motors) are frequently specified here to avoid running three separate pump/motor assemblies bolted to the same power unit skid.

Maintenance and Sourcing Considerations

Cartridge Replacement vs. Full Pump Replacement

Because the T67EDC/T67EDCS is cartridge-based, a maintenance team dealing with declining volumetric efficiency or increased noise doesn't necessarily need to replace the entire pump body. Pulling and replacing the affected cartridge — matched by its displacement code — is usually the lower-cost, lower-downtime fix, provided the housing and shaft are still within tolerance.

Cross-Reference and Interchange Parts

The Denison T6/T7/T67 lineup has direct functional overlap with Eaton Vickers vane pump cartridges, and several third-party distributors supply cross-reference cartridges and full assembled pumps built to the same displacement and pressure specifications. If you're sourcing a replacement from a nameplate that's partially worn or from an older model number, matching the full coded designation (cartridge sizes, shaft type, seal material, rotation, porting) is essential — two pumps that look identical from across the shop floor can have meaningfully different displacement or pressure ratings.

Seal and Fluid Compatibility Checks

Before putting a T67EDC/T67EDCS into service with anything other than standard anti-wear mineral oil — particularly fire-resistant or water-based fluids — confirm the seal material specified in the model code is compatible. Running the wrong seal compound against a water-glycol fluid is a common, avoidable cause of premature seal failure.

Selection Table

Q1: Is the T67EDC a fixed or variable displacement pump?

A1: It's a fixed-displacement pump. Flow output at a given cartridge is set by its displacement rating and shaft speed, not by an internal compensator, though system pressure can still be controlled externally with relief or pressure-compensated valves in the circuit.

Q2: What industries typically use the T67EDC/T67EDCS?

A2: Plastic injection molding, die-casting, forging presses, machine tools, and other equipment that needs multiple simultaneous or sequential hydraulic flow/pressure stages from a single pump/motor assembly.
