Connect only hydraulic lines that are match theaxial piston unit port
(pressurelevel, size, system ofunits).
Observe the following notes when routing the suction, pressure and drain lines.
• Lines and hoses must be installed without pre-charge pressure, so that no further
mechanical forces are applied during operation that will reduce the service life of
the axial piston unit and, if applicable, the entire machine/system.
• Use suitable seals assealing material.
• Suction line (pipe orhose)
–The suction line should beasshort and straight aspossible.
–Measure theline cross-section ofthesuction line sothepressure atthesuction
port does not drop below theminimum permissible pressure. Make sure
themaximumsuction pressure isnot exceeded (e.g. when prefilling).
–Make sure theconnections and connecting elements are airtight.
–The hose must bepressure-resistant, also toexternal air pressure.
• Pressure line
–For the pressure lines, use only pipes, hoses and connecting elements rated for
the working pressure range specified on the data sheet (Part II); see Table 15.
• Drain line
–Always route the drain lines so that the case is constantly filled with
hydraulicfluid and to ensure that no air gets through the shaft seal even during
extended standstill periods.
–Under no operating circumstances may the case pressure exceed the maximum
values specified for the axial piston unit in the data sheet (Part II).
–The drain line inflow in the reservoir must always be below the minimum fluid
level under all conditions (see chapter 7.3 "Installation position" on page 32).
• If theaxial piston unit isequipped with installed screw fittings, do not remove
them. Screw thestud end ofthefitting directly into theinstalled fitting.
Axial piston units are used inapplication areas that use themetric system aswell
astheAnglo-American (imperial) and theJapanese measuring system
(JIS–JapanIndustrial Standard). Various kinds ofseals are also used.
The system ofunits, thekind ofseal and thesize offemale thread and stud ends
(e.g. threaded plug) must all match.
There isarisk ofconfusion due tothe limited ways ofvisually telling them apart.
WARNING! Leaky andbursting stud ends!
If a stud end with a measurement system, seal type and size that are different from
the female thread is pressurized, the threaded plug may loosen itself or even be
propelled out of the hole. This can result inserious injury and property damage.
Hydraulic fluid can escape from this leakage point.
