2 2/60 Bosch Rexroth Corporation Hydraulics AZPF RA 10089/08.11 General Rexroth external gear pumps are available as standard gear pumps in the B, F, N and G series, and as SILENCE gear pumps in the S, T and U series. 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 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. 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 bearing is controlled by the admission of operating pressure to the rear of the bearing bushings. 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 case.

10 10/60 Bosch Rexroth Corporation Hydraulics AZPF RA 10089/08.11 Gear pumps with integral valves In order to reduce external pipework it is possible to incorporate 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 suction port or distributed externally to other items of equipment. upon request Q const. Q const. Q const. p1 p 1 3-way flow-control valve.

19 AZPF RA 10089/08.11 Hydraulics Bosch Rexroth Corporation 19/60 Multiple gear pumps Gear pumps are well-suited to tandem combinations of pumps in which the drive shaft of the first pump is extended to drive a second pump and sometimes a third pump in the same manner. A coupling is fitted between each pair of pumps. In most cases each pump is isolated from its neighbor, i.e. the suction ports are separate from one another. A common suction port is also possible as an option. Caution: Basically, the specifications for the single pumps apply, but with certain restrictions: Max. speed: This is determined by the highest rated pump speed in use. Pressures: These are restricted by the strength of the drive shaft, the through drives and the drivers. Appropriate data is given in the dimensional drawings. Pressure restrictions during standard through drive In the case of series S, the driver for the second pumping stage can carry a load of up to M max. = 65 Nm, i.e. there is a pressure restriction for the second stage and any further stages.

53 AZPF RA 10089/08.11 Hydraulics Bosch Rexroth Corporation 53/60 Notes for commissioning Filter recommendation The majority of premature failures in external gear pumps are caused by contaminated pressure fluid. As a warranty cannot be issued for dirt-specific wear, we recommend filtration compliant with cleanliness level 20/18/15 ISO 4406 (1999), which reduces the degree of contamination to a permissible dimension in terms of the size and concentration of dirt particles. We recommend that a full-flow filter always be used. Basic contamination of the pressure fluid used may not exceed class 20/18/15 according to ISO 4406 (1999). Experience has shown that new fluid quite often lies above this value. In such instances a filling device with special filter should be used. General The pumps supplied by us have been checked for function and performance. No modifications of any kind may be made to the pumps; any such changes will render the warranty null and void. Pump may only be operated in compliance with permitted data (see pages 16 19). Technical data All stated technical data is dependent on production toler ances and is valid for specific marginal conditions. Note that, as a consequence, scattering is possible, and at certain marginal conditions (e.g. viscosity) the technical data may change. Characteristics When designing the external gear pump, note the maximum possible service data based on the characteristics displayed on pages 11 to 15. Additional information on the proper handling of hydraulic products from Bosch Rexroth is available in our document: General product information for hydraulic products RE You can find further information in our publication: General Operating Instructions for External Gear Units RE B1.

You only need to specify your requirements: From the displacement, direction of rotation, drive shaft, connection flange right up to the required rear cover. You immediately receive a project drawing (PDF format) if a configuration already exists. You receive the price of the configured external gear unit upon request. The AZ configurator assists you to configure your individual external gear unit easily and userfriendly all data needed for project planning are acquired thru menu guidance. Selection is made either on an ordering code or your technical requirements. This means that you can search for external gear units that have already been configured, or you specify the configuration variant of the external gear unit based upon the operating parameters you require. If the external gear unit you selected has been released you will receive the part number, ordering code and a detailed installation drawing. If your special configuration is not available please send your specification to Rexroth. One of our employees will then contact you.
