Parker Denison T67B Single Hydraulic Vane Pump

The T67B is a fixed-displacement, cartridge-style single-vane pump manufactured by Parker Hannifin's Vane Pump Division under the Denison Hydraulics brand. It belongs to the T67 series, which uses "Size B" cartridge kits — the displacement class that sits between the smaller T6C-style pumps and the larger, higher-flow options in the T6/T7 range.

Instead of being a sealed, non-serviceable unit, the T67B is built around a replaceable cartridge (rotor, vanes, cam ring, and pressure plates) housed inside a cast body. That's the defining feature of the whole Denison vane pump philosophy: when the pump loses efficiency, you don't scrap the housing — you swap the cartridge kit and get a like-new pump.

How the T67B Vane Pump Works

The Basic Operating Principle

A vane pump generates flow using a rotor with sliding vanes that ride inside an elliptical (or double-lobed) cam ring. As the rotor spins, centrifugal force and, in balanced designs, hydraulic pressure push the vanes outward against the cam ring's inner surface. This creates expanding and contracting chambers between adjacent vanes.

On the intake side, the expanding chamber pulls fluid in from the reservoir.

As the rotor continues turning, the chamber contracts against the cam profile, forcing fluid out through the discharge port at system pressure.

Because the T67B uses a balanced cartridge design, the cam ring has two lobes rather than one. This means each vane experiences two pumping cycles per revolution, and — critically — the pressure loads on opposite sides of the rotor cancel each other out. That balancing act is why vane pumps like the T67B run with comparatively low shaft-bearing loads, which translates directly into longer bearing and seal life compared to unbalanced pump designs.

Why the Cartridge Design Matters

The T67B's cartridge concept deserves its own explanation, because it's the main reason these pumps have such a strong reputation in industrial plants.

Think of the cartridge as the pump's "wear engine" — the rotor, vanes, cam ring, and side plates that actually do the work of moving fluid. Everything around it (the housing, shaft, bearings, ports) is built to last essentially indefinitely under normal conditions. When the cartridge wears down after years of duty, a technician can pull the old cartridge kit and drop in a new one in a fraction of the time — and cost — of replacing an entire pump.

Typical Applications

The T67B's displacement range and pressure capability make it a natural fit for equipment where moderate flow and dependable pressure matter more than sheer volume. Common applications include:

Injection molding and die casting machines — where consistent clamp pressure is non-negotiable

Machine tools — CNC clamping, tool changers, and hydraulic chucks

Metal stamping and forming presses — mid-tonnage presses that don't need the flow of a large piston pump

Material handling equipment — hydraulic lifts, conveyors, and packaging machinery

Industrial power units (HPUs) — standalone hydraulic power packs supplying multiple downstream actuators

Selection Table

Q1: Is the T67B a fixed or variable displacement pump?

A1: Fixed displacement. It delivers a constant volume of fluid per shaft revolution, determined by the cartridge installed. Parker's variable-displacement vane pumps use a different product line.

Q2: Can the T67B be rebuilt, or does it need full replacement when worn?

A2: It can be rebuilt. The cartridge-based design is specifically intended to let a worn pump be restored to near-original performance by replacing the cartridge kit, shaft assembly, and seals rather than the entire pump housing.
