Abstract (en)
A magnetic drive pump (1) includes a motor unit (3) and a leak detector (4). The motor unit (3) includes an inner case body (32) and an outer case body (33). The inner case body (32) has an inner end wall (322) . The outer case body (33) is sleeved on the inner case body (32) and has an outer end wall (332). The outer end wall (332) cooperates with the inner end wall (322) to define a liquid-receiving space (337) therebetween. The leak detector (4) is disposed on one side of the outer end wall (332) opposite to the liquid-receiving space (337) and includes a sensor (41) for detecting a change in electrostatic capacity between the liquid-receiving space (337) and the sensor (41).
