1) Based on an operating viscosity of 140 mm 2 /s (cSt) at a back pressure of p = 5 bar.
2) The operating mode S3 (periodic duty) describes the ratio of pump cycle time to subsequent downtimes time. If the relative ON-time is
20 % and the duty cycle time is 1.25 to 25 min., then the limit values are as follows:
Min. duty cycle time: 1,25 min×0,2 = 0,25 min. Pump cycle time with subsequent downtime of 1 min. Max. duty cycle time: 25 min×0.2 =
5 min. Pump cycle time with subsequent downtime of 20 min.
3) When switching inductive loads, take appropriate measures to protect contacts.
4) Minimum short-circuit current of 6 A must be ensured.
