• 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 prelling).
– 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 specied in data sheet 92802 (see Table 9).
• Drain line
– Always route the drain lines so that the housing is constantly lled with
hydraulic uid and to ensure no air gets through the shaft seal, even during
extended standstill periods.
– The case pressure must never exceed the limit values specied for the
axial piston unit in the data sheet.
– The drain line inow in the reservoir should always be below the minimum
uid level (see chapter 7.3 "Installation position" on page 28).
• If the axial piston unit is equipped with assembled screw ttings, do not remove
them. Screw the stud end of the tting directly into the installed tting.
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.
