Approvals
All these pumps are approved in accordance with national and international standards (IEC 34-1, CSA). They are also available in explosion-proof versions: Factory Mutual (FM) and European Norm (EN).

Materials
ASTM 316L stainless steel provides excellent corrosion resistance in most liquids. ASTM 304 stainless steel is available for less demanding applications (Cl < 200ppm)

Electric motor
Multipole squirrel cage induction motor with thermal overload protection. Designed for direct on-line start.

Bearings
The shaft is supported by one main bearing at the propeller end and, a double bearing at the rear end.

Plug-in seal
In-house designed shaft seals, combined into one, rigid plug-in unit, protect the motor from media intrusion.

Seal housing
Seal housing containing barrier fluid. This fluid also lubricates and cools the seal.

Inlet cone
The uniquely contoured inlet cone minimizes dynamic loss and tip vortices.
