Detial Image

POOCCA PA-AZPF series external gear pumps can be combined with tandem pumps. Examples: PA-AZPFF, PA-AZPFB, PA-AZPNF, PA-AZPGF, etc.

The POOCCA PA-AZPF Series external gear pump consists essentially of a pair of gears supported in bearing bushings, and the case with a front and a rear cover. The drive shaft protrudes from the front cover where it is sealed by the shaft seal ring. The bearing forces are absorbed by special bearing bushings with sufficient elasticity to produce surface contact instead of line contact. 

They also ensure excellent resistance to galling – especially at low speed. The gears have 12 teeth. This keeps both flow pulsation and noise emission to a minimum.

Gear pumps with integral valves

In order to reduce external pipework it is possible to incor- porate a flow-control valve or pressure-relief valve in the rear cover of the gear pump. 

A typical application of this is in the supply of hydraulic oil in power steering systems. The pump delivers a constant flow irrespective of the speed at which it is driven.

The excess flow is either returned internally to the suc- tion port or distributed externally to other items of equipment.

Application Equipment

Mainly used in machine tools, hydraulic systems of national steel rolling equipment, agricultural and forestry machinery, engineering machinery, marine machinery, aviation technology, mobile machinery applications, mechanical applications, engineering and factory automation
