External gear pumps are the most popular pumps used in modern hydraulic systems. They feature versatility, strength and long useful life. Their simple construction ensures limited purchase costs and servicing.
Pump body, flange, and cover are made of special high-resistent aluminum alloys for minimized deformation even when subject to high pressure, be i continuous or intermittent or peak pressure. The body is profiled by means of extrusion, whereas flange and cover are obtained by mens of die-casting even gravity die-casting for some models.)
Gears are made of special steel. Their manufacturing process includes casehardening and quench hardening. Then gears are ground and finished so as to have a high degree of surface finishing. Proper tooth profile design ad geometric proportions ensure low pulsation levels a d low noise levels during pump operation. Brushes are made of low-friction and high-resistant aluminum alloy and manufactured from die-casting.
