Parker Denison T67EC fixed displacement hydraulic vane pump

The T67EC is a fixed displacement, single or double vane pump. Its operation is elegantly simple yet highly effective: a rotor with sliding vanes spins within a cam ring. Centrifugal force, often assisted by pressurized fluid, pushes the vanes against the ring's inner surface, creating expanding and contracting chambers that move hydraulic fluid from the inlet to the outlet.

Operational Advantages: Why Specify the T67EC?

The T67EC is not merely a component; it is a solution for specific system challenges. Its design yields several tangible benefits.

Smooth, Low-Pulsation Flow Output

The nature of vane pump operation generates significantly less flow ripple and pressure pulsation compared to gear pumps of similar size. This leads to:

Quieter System Operation: Reduced noise and vibration, contributing to a better working environment.

Enhanced Component Longevity: Less pulsation means reduced stress on system piping, valves, and actuators, minimizing fatigue-related failures.

Robustness and Contamination Tolerance

While all hydraulic systems strive for clean fluid, the T67EC’s vane design is inherently more forgiving of moderate fluid contamination than high-precision piston pumps. This robustness translates to:

Reliability in Challenging Environments: Greater suitability for applications where perfect filtration is difficult to maintain.

Reduced Downtime: Less sensitivity to minor contaminant ingress promotes longer service intervals.

Application Examples: Where the T67EC Excels

This pump’s profile makes it ideal for applications requiring reliable, continuous duty power in a compact form factor.

1.Injection Molding Machines: Provides the steady, high-volume flow needed for mold clamping and plastication circuits, where smooth operation is critical for part quality.

2.Industrial Presses (Punch, Stamping, Bending): Delivers the reliable power for rapid ram approaches and high-force pressing cycles, enduring the frequent pressure cycles.

3.Machine Tool Hydraulic Power Units (HPUs): Serves as the heart of HPUs for CNC lathes, machining centers, and EDM machines, powering tool changers, clamps, and index tables.

4.Material Handling Equipment: Powers the hydraulics on large conveyor drives, palletizers, and automated storage/retrieval systems.

Selection Table

Q1:What is the primary difference between a fixed displacement (like the T67EC) and a variable displacement vane pump?

A1:A fixed displacement pump moves a set volume of fluid per revolution. Flow is controlled by throttling with valves or by changing pump speed (RPM). A variable displacement pump can internally alter its chamber volume, changing its output per revolution to meet demand directly, often improving system efficiency in applications with varying flow needs.

Q2:Can this pump be used in a closed-loop circuit (e.g., on a hydrostatic transmission)?

A2: The standard T67EC is configured as an open-loop pump, meaning it typically draws from a reservoir. For closed-loop circuits, a pump specifically designed with case drain and charge pump provisions, like a piston pump or a specialized vane pump, is required.
