Product description
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)
▪ Motor housing: EN-GJL-250 (ASTM A48 Class 35/40B)
▪ Seal on the motor side:
– "H" = NBR (nitrile)
– "G" = carbon/ceramic or SiC/SiC
– "K" = SiC/SiC
▪ Seal on the fluid side: SiC/SiC
▪ Seal, static: NBR (nitrile)
The precise details of the materials are shown in the respective configuration.

All monitoring devices fitted must be connected at all times!
Monitoring of motor compartment
The motor compartment monitoring protects the motor winding from short-circuits. The
moisture is measured by an electrode.
Monitoring the terminal room and motor compartment
The terminal room and motor compartment monitoring protects the motor terminals and
winding from short-circuits. An electrode in both the terminal room and the motor com-
partment measures the moisture content.
Monitoring the motor winding
The thermal motor monitor protects the motor winding from overheating. A temperature
limit with bimetallic strip is built-in as standard.
As an option, the temperature can also be measured with a PTC sensor. The thermal motor
monitoring can also be designed as temperature control. This allows the measurement of
two temperatures. When the low temperature is reached, an automatic reactivation can be
initiated after cooling the motor. When the high temperature is reached, the unit must de-
activate with reactivation lock.
