2 The displacements are graded by different gear widths. Further configuration variants are giv-en by different flanges, shafts, valve arrangements and multiple pump seal Radial seal External pressure zone FlangeCompensation forcesSealing zoneInternal pressure zone 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 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 pump axial compensationThe internal sealing is achieved by forces which are propor-tional to delivery pressure.

3 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 be-tween the gear teeth and the bearing is controlled by the ad-mission of operating pressure to the rear of the bearing bush-ings. Special seals form the boundary of the zone. The radial clearance at the tips of the gear teeth is sealed by internal forces pushing them against the Retaining ring2 Shaft seal ring3 Front cover4 Slide bearing5 Centering pin6 Gear (driven)7 Gear (drive) 8 Case seal 9 Pump case10 Bearing11 Axial zone seal12 Support13 End cover14 Fixing screws1234567891011121314 ConstructionHydraulics Bosch Rexroth CorporationAZPF RA 10089 overview of "Series F" standard types4/60 Bosch Rexroth Corporation HydraulicsAZPF RA 10089 shaftsFront flangeLine connectionsMatching front flangeCConical 1:5(Tapered key)BPSC onical 1:5for flange A(Tapered key)AHConical 1.
