 Specifications/General Technical Datas

Construction

 

 

The 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 obsorbed by special slide bearings with sufficient elasticity to produce surface contact instead of line contact. They also ensure excellent resistence to galling - especially at low speed. The gears have 12 teeth. This keeps both flow pulsation and noise emission to a minimum.

 

The internal sealing is achieved by forces which are proportional to delivery pressure. This ensures optimum efficiency. The bearings provide the seal at the ends of the gaps between the teeth which carry the pressurized oil. The sealing zone between the gear teeth and the bearings is controlled by the admission of operating pressure to the rear of the bearings. Special seals form the boundary of the zone. The radial clearance at the gear teeth is sealed by internal forces pushing them against the case.
