Motor

Rewindable, corrosion-resistant alternating current motor or three-phase current motor for direct starting. Sealed using a mechanical seal with self-lubricating bearings with oil filling.

Cooling

The motor is cooled by the fluid. The motor must always be immersed when operated. The limit value for the maximum fluid temperature may not be exceeded. The limit value for the minimum volume flow may not be exceeded. Vertical installation is possible with or without cooling shroud. A cooling shroud is required for horizontal installation.
