The invention relates to a pump arrangement () with at least one temperature-controllable housing part, wherein at least one temperature-controllable housing part () comprises a first wall () that is in contact with the temperature-controllable medium and a second wall () that is at a distance from the first wall (). The first wall () and the second wall () form a temperature control chamber ().

Pump arrangement with a temperature controllable housing part

A split can for a magnetic coupling includes a cylindrical jacket region and a base region connected to a first end of the jacket region. The jacket region has an inner wall and an outer wall enclosing the inner wall. The inner wall and the outer wall are spaced apart from each other in the radial direction by a gap, with the inner wall being integrally joined to the outer wall by a plurality of webs. The gap may be provided with a control medium which may be monitored to detect changes in one or more characteristics of the control medium indicative of split can leakage.

Split can

A pump assembly, in particular a centrifugal pump assembly, includes a hydraulic housing having an intake port, a pressure port, a flow chamber at least partly delimited by the hydraulic housing. The hydraulic housing includes has an inner wall at least partially delimiting the flow chamber and an outer wall at an axial distance from the inner wall. A temperature-control chamber is located between the inner wall and outer wall.
