Gear Pump

For truck-mounted hydraulic systems, the most typical design in use is the equipment pump. This design is definitely characterized as having fewer moving parts, being easy to provider, more tolerant of contamination than other designs and relatively inexpensive. Gear pumps are set displacement, also called positive displacement, pumps. This means the same volume of flow is created with each rotation of the pump’s shaft. Gear pumps are rated when it comes to the pump’s maximum pressure rating, cubic in . displacement and maximum insight speed limitation.

Generally, gear pumps are used in open center hydraulic systems. Gear pumps trap essential oil in the areas between the the teeth of the pump’s two gears and the body of the pump, transport it around the circumference of the gear cavity and then drive it through the wall plug port as the gears mesh. Behind the brass alloy thrust plates, or wear plates, a little amount of pressurized oil pushes the Gear Pump china plates tightly against the gear ends to boost pump efficiency.
