Product description
motor can be used in continuous duty both immersed and non-immersed. The connec-
tion cable has bare cable ends. For single-phase current motors, the operating capa-
citor is integrated in the connection cable.
The seal for the fluid and the motor compartment is made via two mechanical seals. The
sealing chamber between the mechanical seals is filled with medical white oil.
The following materials are used in the standard version:
▪ Pump housing: EN-GJL-250 (ASTM A48 Class 35/40B)
▪ Impeller: EN-GJL-250 (ASTM A48 Class 35/40B) or EN-GJS-500-7
(ASTM A536 70-50-05)
▪ Motor housing: G-AlSi12
▪ Seal on the motor side: C/Al
▪ Seal on the fluid side: SiC/SiC
▪ Seal, static: FPM (FKM)
The precise details of the materials are shown in the respective configuration.
Operating mode S1: Continuous duty
The pump can operate continuously at the rated load without exceeding the permiss-
ible temperature.
Operating mode: Non-immersed operation
The "non-immersed operation" operating mode describes the possibility of the motor
emerging during the drainage pumping sequence. This allows a further lowering of the
water level as far as the upper edge of the hydraulics. Observe the following points dur-
ing non-immersed operation:
▪ Operating mode: Continuous duty (S1).
▪ Max. fluid and ambient temperature: The max. ambient temperature corresponds to the
max. fluid temperature shown on the rating plate.
Operation on the frequency converter is not permitted.
Operation in an explosive atmosphere is not permitted.
