Slotted tube motor pump has rotor enclosed in hermetically sealed manner by slotted tube, stator engaging around slotted tube, with motor cooling that cools drive motor via outer periphery of stator

摘要

The slotted tube motor pump has an electric drive motor (2) whose rotor (3), which has a drive connection to the pump (6), is enclosed in a hermetically sealed manner by a slotted tube (5) and whose stator (4) engages around the slotted tube and motor cooling (9) associated with the motor. The motor cooling cools the drive motor via the outer periphery of the stator.
