Product Portfolio
  • Hydraulic Pumps

  • At Oilgear, our axial piston pump line was developed to achieve one primary goal:

    To provide our customers with a low cost of ownership.

    Our superior products are designed to last longer and consume less energy than our competitors' products, making Oilgear the industry leader. We provide the most durable pump and control systems to produce the fastest response times.

    Axial piston and check valve pumps are able to compress the fluid, which is then delivered under pressure. This type of pump is able to take a pressure of 650 bars for great volumetric returns of 98%.

    Oilgear's pumps, both Variable and Fixed displacement, have earned the reputation of being the "Rolls Royce" on the market, especially for the needs of the the heavy-duty applications.

    Hydraulic system performance has always been linked closely to the quality and cleanliness of the fluids being used. Oilgear's advanced hydrodynamic bearing design was created for use with environmentally-friendly fluids, such as water or water glycol. This technology was engineered to produce industry-leading efficiencies as new challenges occur..

  • Hydraulic Motors

  • Oilgear's MFW and MVW fixed and variable displacement bi-directional high-speed motors are offered in two frame sizes and four displacements, allowing for greater flexibility to match pressure and capacity.

    The MFW fixed displacement motor maintains constant torque with varying horsepower. Because the motor is fixed, maximum torque is available at all times when in operation, whether the motor is stalled or operating at full rpm. Horsepower output is approximately proportional to speed, making it is possible to reduce pump delivery when stalled, or bring the motor and load up to speed while maintaining full torque.

    The MVW variable displacement motor can operate with constant horsepower and variable torque, or with constant torque or constant horsepower. When operating with constant horsepower and varying torque, the MVW motor can adjust speed over a 4:1 range when driven by a fixed delivery hydrostatic pump. When a variable displacement motor is driven by a variable delivery pump, constant torque or constant horsepower at variable speed can occur.
