Gear Pump

For truck-mounted hydraulic systems, the most common design in use may be the gear pump. This design can be characterized as having fewer shifting parts, being easy to provider, more tolerant of contamination than other designs and fairly inexpensive. Gear pumps are fixed displacement, also called positive displacement, pumps. This implies the same volume of movement is produced with each rotation of the pump’s shaft. Gear pumps are rated in terms of the pump’s optimum pressure rating, cubic ” displacement and maximum input speed limitation.

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