Parker Denison T6CY single hydraulic vane pump

The T6CY is a single-vane pump from Parker Hannifin's T6 Series (Size C), manufactured under the Denison Hydraulics vane pump technology that Parker acquired. It uses a fixed-displacement Denison vane design and is built around a cartridge-style construction, meaning the internal wear components — rotor, ring, vanes — are housed in a replaceable cartridge rather than machined directly into the pump body. That single design choice is a big part of why these pumps are so serviceable in the field.

Key Design Features

Balanced Pin-Vane Construction

The T6CY is designed for higher operating pressure and greater flow at the same housing size compared to earlier vane pump designs. Its balanced pin-vane design applies outlet pressure continuously only to the pin, which provides steady, light force against the vane rather than slamming full system pressure against the vane tip. In practice, this means less wear, quieter operation, and a longer cartridge life than older, non-balanced vane designs.

Cartridge-Based Serviceability

Because the rotating group lives in a self-contained cartridge, a worn T6CY pump doesn't need a full rebuild or replacement — technicians can swap the cartridge kit and get the pump back to like-new volumetric efficiency in a fraction of the time a full teardown would take.

Efficiency and Speed Range

The T6 series delivers high volumetric efficiency, typically around 94%, which reduces heat generation and allows operating speeds as low as 600 RPM at full pressure. Mechanical efficiency is similarly strong at roughly 94%, keeping energy consumption down. The pump's wide speed range — from 600 RPM up to 2800 RPM — combined with the availability of large cartridge displacements lets engineers optimize for the lowest noise level in the smallest possible envelope.

High Pressure Capability, Compact Footprint

These pumps reduce installation costs by delivering high-pressure capability — up to 275 bar — within a small operating envelope, and the double-lip vane design gives high resistance to particle contamination, further extending pump life in less-than-pristine hydraulic fluid conditions.

Typical Applications

The T6CY's blend of moderate-to-high pressure capability, compact size, and quiet operation makes it a natural fit for:

Injection molding machine hydraulic power units

Industrial presses and stamping equipment

Machine tool hydraulic circuits (clamping, indexing, tool changers)

Mobile and stationary power units where noise and heat generation matter

Circuits requiring a fixed, predictable flow rather than variable displacement

Choosing the Right T6CY for Your System

When specifying a T6CY, work backward from your circuit requirements:

1. Determine required flow (GPM or LPM) at your target shaft speed — this tells you the displacement (ml/rev) you need.

2. Confirm your system's peak pressure stays within the pump's rated envelope.

3. Check porting orientation (the "R" or "L" in the model code) against your manifold layout.

4. Match the mounting flange (the "B" designation) to your motor or drive coupling.

5. Plan for cartridge replacement rather than full pump replacement when service life is reached — it's faster and cheaper.

Selection Table

Q1: Can I rebuild a T6CY myself, or does it need factory service?

A1: Because of the cartridge-based design, most maintenance is a cartridge swap rather than a full rebuild — well within reach of a competent hydraulics technician with the correct kit and torque spec.

Q2: What mounting torque should I use when reinstalling a T6CY?

A2: 159 Nm (117 ft-lbs) for the housing screws, applied gradually in stages rather than all at once.

Q3: How to purchase a T6CY hydraulic pump?

A3: You can visit https://www.baolilaihydraulic.com/contact/ to contact us and purchase our products through various methods.

Q4: What is the price and delivery time of the T6CY hydraulic pump?

A4: The specific price and delivery time will be provided based on the specific model you provide.
