Product description
▪ Bare cable end
▪ With plug and fitted float switch
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.
▪ Pump housing: EN-AC-AlSi10Mg + NBR-70
▪ Impeller: 1.4470
▪ Suction strainer: 1.4301
▪ Cooling shroud: 1.4301
▪ Motor housing: EN-AC-AlSi10Mg
▪ Shaft: 1.4404
▪ Seal on the motor side: SiC/SiC
▪ Seal on the fluid side: SiC/SiC
▪ Static seal: NBR
Version "A" of the pump is equipped with a plug and float switch. Depending on the fill
level, it is possible to switch the pump on and off automatically using the float switch.
The plug is designed for use in commercially available shock-proof or CEE sockets and
is not overflow-proof.
The thermal motor monitoring protects the motor winding from overheating. A tem-
perature limiter with a bimetallic strip is fitted as standard. The motor monitoring is de-
signed as follows:
▪ Version with bare cable end: The thermal motor monitoring is self-switching. This
means that the motor is switched off if it overheats and will be automatically switched
on again when it has cooled down.
▪ Version "A": The thermal motor monitoring is fitted to the plug on the motor protection
relay.
Operating mode S1: Continuous duty
The pump can operate continuously at the rated load without exceeding the permiss-
ible temperature.
"Slurping operation" operating mode
Slurping operation facilitates the pumping of very small amounts of fluid. CAU-
TION! Never allow the machine to dry run! Non-compliance can lead to irreparable
damage!
Operation on the frequency converter is not permitted.
Operation in an explosive atmosphere is not permitted.
