2 2 ZPW Standard performance External gear pump Functional description Functional description General Rexroth external gear pumps are available as standard performance gear pumps in the series W. The displacements are graded by different gear widths. Further configuration variants are given by different flanges, shafts, valve arrangements and multiple pump combinations. Construction The external gear pump consists essentially of a pair of gear wheels supported in bearing bushes and the housing with a front and a rear cover. The drive shaft protrudes from the front cover where it is usually sealed by the shaft seal. The bearing forces are absorbed by slide bearings. These were designed for high pressures and have excellent emergency running properties, especially at low rotational speeds. The gear wheels have 12 teeth. This keeps both flow pulsation and noise emission to a minimum. The internal sealing of the pressure chambers is achieved by delivery pressure-dependent forces. This ensures optimum efficiency. On the rear side, the movable bearing bushes are pressurized with working pressure and pressed as seals against the gear wheels. The pressurized compression springs are limited by special seals. The seal on the area between the gear teeth and the housing is ensured by the smallest of gaps that adjust depending on the pressure between the gear teeth and housing. xial compensation standard performance xial seal External pressure field Internal pressure field Radial sealing Rear cover Front cover Sealing zone Compensation forces Layout ZPW (schematic diagram) Snap ring 2 Shaft seal 3 Front cover 4 Slide bearings 5 Centering pin 6 Gear wheel 7 Drive shaft 8 Housing seal ring 9 Pump housing 1 Bearing bushing 11 xial field seal 12 Support element 13 Rear cover 14 Hexagon screw Bosch Rexroth G, RE 19/6.216

The mounting of conventional screw fittings in accordance with DIN EN ISO 1179, 6149, 9974 etc. is easily possible. Clockwise or counter-clockwise, the pump may only be driven in the direction indicated Radial and axial forces only after consultation Hydraulic Hydraulic fluid Mineral oil according to DIN 51524, 1-3, however under higher load at least HLP compliant with DIN Part 2 is recommended.

32 32 ZPW Standard performance External gear pump Notes on commissioning Notes on commissioning General Pumps delivered by Bosch Rexroth are tested for function and performance. No changes of any nature may be made, otherwise the warranty is rendered void. The pump may only be operated with the permissible data (see page 6). Technical data ll mentioned technical data are dependent on manufacturing tolerances and are applicable for certain boundary conditions. Note that certain deviations are therefore possible and that technical data may vary when certain boundary conditions (e.g., viscosity) change. Characteristic curves When dimensioning the gear pump, observe the maximum possible application data on the basis of the characteristic curves shown starting on page 8. Filter recommendation Since the majority of premature failures in gear pumps occur due to contaminated hydraulic fluid, filtration should maintain a cleanliness level of 2/18/15 as defined by ISO 446. Cleanliness level 2/18/15 can reduce contamination to an acceptable degree in terms of particle size and concentration. Bosch Rexroth generally recommends full-flow filtration. Basic contamination of the hydraulic fluid used may not exceed class 2/18/15 according to ISO 446. New fluids are often above this value. In such instances, a filling device with a special filter should be used. Bosch Rexroth is not liable for wear due to contamination. Scope of delivery The scope of delivery includes the components with the characteristics described under type codes and dimensions starting on page 16. Further information Further information on installation, commissioning, and operation can be found in the publication 712 B1: General Operating Instructions for External Gear Units. Extensive notes and suggestions can be found in the Hydraulic Trainer, volume 3: Planning and Design of Hydraulic Power Systems, order number R Bosch Rexroth G, RE 19/6.216
