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 simple to provider, more tolerant of contamination than additional designs and relatively inexpensive. Gear pumps are set displacement, also called positive displacement, pumps. This means the same volume of movement is created with each rotation of the pump’s shaft. Gear pumps are rated in Gear Pump china conditions of the pump’s optimum pressure rating, cubic inch displacement and maximum input speed limitation.

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