Transmission Pumps Medal Hydraulics has into it product lines transmission pumps. The transmission pump is the heart of your transmission, pumping hydraulic transmission fluid throughout the system. Its referred as the gear pump and has two gears. One gear is powered by the torque convertor hub which engages the inside gear of the pump. The other gear in the transmission pump is the outside gear which is driven by the inside gear. When these two gears run and rotate together they create a suction effect that keeps the transmission fluid moving. As the pressure increases the hydraulic system by the transmission pump its becomes effective. Transmission Pump produces pressure to push the...

Hydraulic Gear Motor   An hydraulic gear motor uses externally mounted gears to produce mechanical energy. Pressurized fluid forces the external gears to turn, producing output torque. External hydraulic gear motors are a cost-effective alternative for rotary drives up to approximately 50 kW. The Medals hydraulic gear motors are available for one direction of rotation or reversible. Our aluminum and Cast iron hydraulic gear motors including fan drive are ideal choice for a range of applications, from small to medium and large off-highway vehicles. As these devices can be found in widely varying applications, hydraulic gear motors are manufactured in a number of radically different types,...

Pumps  A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load. When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development...

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...
