denison hydraulics and systems leader About Denison Hydraulics and Products

Denison hydraulic vane pumps feature greater flow for the envelop size is achieved by increased displacement cam rings. Higher pressure ratings to 4000 psi reduce size and cost of actuators, valves and lines- give extended life at reduced pressures. Better efficiency under load increases productivity, reduces heating and operating cost. Mounting flexibility is greatest in this double pump- four positions of the shaft end outlet and eight positions of the cap end outlet, relative to inlet. This reduces mounting costs and improves performance. Hydrostatic transmission pumps/motors & open loop pumps feature high power, compact, smallest and lightest transmission package in its power class for the mobile, marine and industrial equipment industries. Pump displacement control is rotary servo with pressure compensator over-rides. Compensator over-ride for the pump is effective in both flow directions, may be vented or remotely pressure controlled together or individually. The company's direct or pilot operated spool valve controlled by solenoids, lever, hydraulic pressure or stem. Subplate or manifold mounting is standard. Economical manufacture to close tolerance ensures interchangeability or circuit modification without the necessity for selective assembly. This is also true for spare parts.

Fluid Power Products and Benefits:
Fluid power is energy transmitted and controlled by means of a pressurized fluid, either liquid or gas. The term fluid power applies to both hydraulics and pneumatics. Hydraulics uses pressurized liquid, for example, oil or water; pneumatics uses compressed air or other neutral gases. Fluid power can be effectively combined with other technologies through the use of sensors, transducers and microprocessors.

Fluid Power Products in General:
Fluid power products are sold as individual components or as systems for the original equipment manufacturing, maintenance, repair and replacement markets. A typical fluid power system includes the following components:

  • Hydraulic pump or air compressor, which converts mechanical power to fluid power.
  • Cylinder or motor, which converts fluid power to linear or rotary mechanical power.
  • Valves, which control the direction, pressure and rate of flow.
  • Filters, regulators and lubricators, which condition the fluid.
  • Manifolds, hose, tube, fittings, couplings, etc., which conduct the fluid between components.
  • Sealing devices, which help contain the fluid.
  • Accumulators and reservoirs, which store the fluid.
  • Instruments such as pressure switches, gauges, flow meters, sensors and transducers, which are used to help monitor the performance of a fluid power system.
