The throughdrive version is designated by the code numbers (K01-K24). Ifno other pumps are factory-mounted, the simple type designationis sufficient.The delivery of a pump with through drive includes the shaftcoupler, the seal and if applicable an adapter flange.Every through drive is closed with a non protective coverupon delivery. Prior to start up this cover must be replaced by apressure tight cover (or a 2nd pump).Through drives can be ordered with a pressure tight cover.Please indicate in clear text.It is permissible to combine two single pumps of the same size (tandem pump) and operate the combination with a max. permissibledynamic acceleration of 10g (98.1 m/s 2 ) without additional support.Size 18 28 45 71 100 140Permissible moment of inertiastatic T m Nm 500 880 1370 2160 3000 4500 1)dynamic at 10g (98.1 m/s 2 ) T m Nm 50 88 137 216 300 450 1)Weight m kg 12 15 21 33 45 60To center of gravity L 1 mm 90 110 130 150 160 1601)4-bolt flange (D)2)2-bolt flange (C) Combination pumps max. permissible as double pump of the same size.3000 2)300 2)m 1 , m 2 , m 3 Weight of pumps [kg]m 1 m 2 m 3l 1 , l 2 , l 3 Distance to center of [mm]gravity1Tm = (m 1 • l 1 + m 2 • l 2 + m 3 • l 3 ) • [Nm]102l 1l 2l 3Overview of through drive mounting optionsThrough drive - A10V(S)O Mounting option - 2. pump ThroughFlangeCoupler for splined Code A10V(S)O/31 A10V(S)O/52 (53) Gear pumpdrive availableon(SAE-J744) shaftSize (shaft) Size (shaft)size82-2 (A) 16-4 (5/8 in) K01 18 (U) 10 (U) (18 (U)) Series F 18 to 14019-4 (3/4 in) K52 18 (S, R) 10 (S) (18 (S, R)) 18 to 140101-2 (B) 22-4 (7/8 in) K68 28 (S, R) 28 (S, R) Series N, G 28 to 14045 (U, W) 1) 45 (U, W) 1)25-4 (1 in) K04 45 (S, R) 45 (S, R) 45 to 10063 (U, W) 2)127-2 (C) 32-4 (1 1/4 in) K07 71 (S, R) 85 (U, W) 3) 71 to 140100 (U) 3)38-4 (1 1/2 in) K24 100 (S) 85 (S) 100 to 140152-4 (4-bolt) 44-4 (1 3/4 in) K17 140 (S) 1401)Not with K68-through drive on main pump size 282)Not with K04-through drive on main pump size 453)Not with K07-through drive on main pump size 71

42/44 Bosch Rexroth AG A10V(S)O Series 31 RE 92701/06.09Installation instructionsGeneralThe pump housing must be filled with fluid during commissioning and operation and must be deaerated. This must also be thecase after prolonged periods of standstill since the system can empty itself through the hydraulic lines.This is especially important with the mounting position „shaft end upwards or downwards“: make sure that the housing is completelyfilled with fluid, to prevent the bearings and shaft seal from running dry and overheating.Connect the highest one of the case drain ports with tubing of the light series wall thickness and the largest size corresponding tothe port size. In order to attain the lowest noise level, all connections (suction, pressure, pilot, and case drain) must be linked byflexible members to tank and try to avoid mounting above the reservoir.In case of combination pumps with different case drain pressures it is necessary that each pump has its own case drain line.In every operating condition the inlet and the case drain lines must always enter the reservoir below the minimum fluid level(h t min = 200 mm). The permissible suction height h depends on the overall suction pressure losses, but may never exceedh S max = 800 mm. The minimum inlet pressure at port S may not fall below the minimum value of p abs min = 0.8 bar under any staticor dynamic condition.Installation positionSee the following examples1 to 15 Recommended positions: 1 and 3.Other installation positions may be possible; please consult us..Mounting below the reservoir (Standard)This is the case whenever the pump is mounted below the min. fluid level.

44/44 Bosch Rexroth AG A10V(S)O Series 31 RE 92701/06.09General instructions––The pump A10V(S)O was designed for operation in open loop circuits––Systems design, installation and commissioning requires trained technicians or tradesmen.––All hydraulic ports can only be used for the fastening of hydraulic service lines.––During and shortly after operation of a pump the housing and especially a solenoid can be extremely hot, avoid being burned;take suitable safety measures (wear protective clothing).––Dependent on the operating conditions of the axial piston pump (operating pressure, fluid temperature) deviations in the performancecurves can occur.––Pressure ports:All materials and port threads are selected and designed in such a manner, that they can withstand the peak pressures.The machine and system manufacturer must ensure, that all connecting elements and hydraulic lines are suitable for the actualoperating pressures.––Pressure cut off and pressure control are not suitable for providing system protection against excessive pressures. A suitableoverall main line relief valve must be incorporated.––All given data and information must be adhered to.––The following tightening torques are valid:- Female threads in the axial piston unit:the maximum permissible tightening torques M GMax are maximum values for the female threads in the pump casting and maynot be exceeded.- Fittings:please comply with the manufacturer‘s information regarding the max. permissible tightening torques for the used fittings.- Fastening bolts:for fastening bolts to DIN 13 we recommend to check the permissible tightening torques in each individual case to VDI 2230.- Plugs:for the metal plugs, supplied with the axial piston unit the following min. required tightening torques M V apply (see table)Port thread sizeMax. perm. tighteningtorque in female threadsM G maxRequired tightening torque ofplugs or fittings M VG 1/4 in ISO 11926 70 Nm7/8-14 UNF-2B ISO 11926 40 Nm 15 Nm 3/16 in1 1/16-12 UNF-2B ISO 11926 360 Nm 147 Nm 9/16 inM14x1,5 DIN 3852 80 Nm 35 Nm 6 mmM16x1,5 DIN 3852 100 Nm 50 Nm 8 mmM18x1,5 DIN 3852 140 Nm 60 Nm 8 mmM22x1,5 DIN 3852 210 Nm 80 Nm 10 mmM27x2 DIN 3852 330 Nm 135 Nm 12 mmAcross the flats in AllanscrewsBosch Rexroth AGHydraulicsAxial Piston UnitsAn den Kelterwiesen 1472160 Horb, GermanyTelefon +49 (0) 74 51 92-0Telefax +49 (0) 74 51 82 21info.brm-ak@boschrexroth.dewww.boschrexroth.com/axial piston units© This document, as well as the data, specifications and other information setforth in it, are the exclusive property of Bosch Rexroth AG.
