Denison Hydraulics Vane Technology

Denison Vane Technology | T-Series Vane Pumps

Multiple vane pumps have been specially designed for the high/low circuit. The combination of different cartridges in double and triple pumps allows low flow at high pressure (300 bar max.) and high flow at lower pressure. This is a clever way to minimize power consumption and optimize your circuit design.

The large variety of options (cam displacement, shaft, porting) allows customized installation.

Cartridge Types

Three different types of vane pump cartridges:

Industrial Cartridges

  • Mobile and Industrial Applications

Mobile Cartridges

  • Mobile and Industrial Applications
  • Cold weather start-up
  • Low Speeds with Low Pressure

Spring Loaded Cartridges

  • For Filter Loops or Boost Pressure
  • Typically pressures less than 20 psi
  • Limited speeds

Cartridge Sizes

Five different sizes vane pump cartridges:

Greater Flow

  • Size A : 5.8 to 40.0 ml/rev
  • Size B : 5.8 to 50.0 ml/rev
  • Size C : 10.8 to 100.0 ml/rev
  • Size D : 44.0 to 158.0 ml/rev
  • Size E : 132.3 to 268.7 ml/rev

Higher Pressure

  • Size A : up to 300 bar max
  • Size B : up to 320 bar max (multiple pumps 300 bar)
  • Size C : up to 275 bar max
