Features ofthe ATEX version
The ATEX version isan advanced development ofthe
A4CSG for compliance with Directive2014/34/EU (ATEX).
External features distinguishing it from the standard pump
asper data sheet 92105 are the ground terminal, the
Ex marking and the CE marking onthe name plate.
For ATEX category II 2G Ex h IIC T4-T1 Gb X, an additional
temperature sensor for monitoring the operation data
issupplied.
Temperature classes per DINENISO80079-36
Depending onthe two temperature classes, T3 and T4,
observe the maximum permissible temperatures
(see "Hydraulic fluid" and "Operating data monitoring –
X parameters").
▶ Sizes 250, 355, 500
▶ Nominal pressure 350 bar
▶ Maximum pressure 400 bar
▶ Closed circuit
