Gear Pump

For truck-mounted hydraulic systems, the most common design in use is the equipment pump. This design is certainly characterized as having fewer shifting parts, being easy to services, more tolerant of contamination than additional designs and relatively inexpensive. Gear pumps are set displacement, also called positive displacement, pumps. This implies the same volume of circulation is created with each rotation of the pump’s shaft. Gear pumps are rated when it comes to the pump’s optimum pressure rating, cubic inch displacement and maximum input speed limitation.

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