Gear Pump

For truck-mounted hydraulic systems, the most common design in use is the gear pump. This design is usually characterized as having fewer moving parts, being simple to provider, more tolerant of contamination than other designs and relatively Gear Pump china inexpensive. Gear pumps are fixed displacement, also called positive displacement, pumps. This implies the same level of circulation is produced with each rotation of the pump’s shaft. Gear pumps are rated with regards to the pump’s maximum pressure rating, cubic in . displacement and maximum insight speed limitation.

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