  • Gear Pump/ Fixed Displacement Gear Pump


Positive fixed displacement external gear pumps, the most popular pumps used in modern hydraulics systems feature versatility, strength and long useful life. Fixed displacement Gear Pump simple construction, compared to other types (piston, orbital, etc) ensures cost effective purchasing and servicing.

A Fixed displacement gear pump is a type where the amount of displacement cannot varied, only by changing the drive speed to the pump

Medal Group has developed fixed displacement  gear pumps and motors based on excellence and operational safety, economic performance, social impact, environmental protection and human valorization, always committed to the construction of the best replacement items for each type of equipment.

These fixed displacement gear pumps have high overall efficiencies, normally above 90%. The product range is available in various mounting formats including SAE and DIN.
A complete range of reversible units and gear motors compliment the range of hydraulic pumps for all types of industrial process, heavy plant, agricultural, offshore
Medals hydraulic fixed displacement gear pumps and motors can work under heavy duty operating conditions and transmit high hydraulic power, feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions and low weight/power ratio. Ideal for both industrial and mobile industry sectors. An Fixed displacement  gear pump is usually limited to a maximum working pressure of 210 bars (21,000 kPa) and a maximum speed of 3,000 rpm. Some manufacturers produce fixed displacement gear pumps with higher working pressures and speeds but these types of pumps tend to be noisy and special precautions may have to be made.
