Features of the ATEX version
The ATEX version is an advanced development of the
A4VSO for compliance with Directive 2014/34/EU (ATEX).
External features distinguishing it from the standard pump
92050 are the ground terminal, the Ex marking and the
CE marking on the name plate.
Temperature classes per DIN EN ISO 80079-36
Depending on the two temperature classes, T3 and T4,
observe the maximum permissible temperatures
(see "Hydraulic fluid" and "Operating data monitoring
– X parameters").
All attachment pumps must match the ATEX classification for the
1)
application in question.
With through-drive shaft, without hub, without intermediate flange,

Notices
▶ ATEX classification: When ordering, please state
which equipment group, category, explosion group,
temperature class and ignition protection type are
required for your planned ATEX application.
▶ Technical data: Compared to the standard pump,
restrictions apply in terms of temperature, case
pressure and bearing flushing/installation position.
▶ Painting/color selection: In order to avoid
mechanically generated sparks from contaminants
made of aluminum with iron oxide and/or particles of
rust of the surface
with corrosion protecting. Please contact your Rexroth
partner for available colors.
▶ Bearing service life: The service life of the bearings
must be calculated. The load cycle forms the basis for
this. Please contact us.
▶ Potential equalization: The pump must be grounded.
For grounding points, see drawings starting on
page 15.
