Problems solved by technology

[0011] Furthermore, conventional sealing caps have the additional disadvantage that they consist of several individual parts, which are mostly connected to one another by welding
If the welds are not welded correctly, leaks can occur at said welds, which further deteriorates the function of the pump
[0012] Furthermore, with such a sealing cover, it becomes difficult or practically impossible to additionally arrange lines which run through possible cooling / heating chambers arranged in the sealing cover

Embodiment Construction

[0035] figure 1 A pump device 1 in the form of a magnetic clutch pump device is shown. The pump device 1 has a multi-part pump housing 2 of a centrifugal pump, which includes a temperature-regulated component 3 designed as a hydraulic housing, a housing cover 4 , bearing bracket webs 5 . , Bearing seat 6 and bearing cover 7.

[0036] The component 3 , which is designed in the present example as a hydraulic housing, has an inlet 9 at the suction connection 8 for sucking in the conveying medium and an outlet 11 at the pressure connection 10 for discharging the conveying medium. Housing cover 4 is arranged on the side of hydraulic housing 3 opposite inlet 9 . The bearing seat web 5 is fastened on that side of the housing cover 4 facing away from the hydraulic housing 3 . The bearing seat 6 is arranged on the side of the bearing seat web 5 opposite the housing cover 4 . The bearing cover 7 is in turn fastened to the side of the bearing housing 6 facing away from the bearing ho...

Abstract

The invention relates to a pump arrangement (1) with at least one temperature-controllable housing part, wherein at least one temperature-controllable housing part (3) comprises a first wall (27) that is in contact with the temperature-controllable medium and a second wall (28) that is at a distance from the first wall (27). The first wall (27) and the second wall (28) form a temperature control chamber (29).

Description

technical field [0001] The invention relates to a pump device having at least one temperature-regulated housing part. Background technique [0002] Such pump arrangements are frequently used in industrial plants, in particular in chemistry and petrochemistry. In this case, a medium is often pumped or conveyed, which medium can only be conveyed or pumped at a certain temperature. [0003] Such a medium is, for example, sulfur. If the temperature drops or rises too much at certain points in the pump during the pumping process, the medium can crystallize and thus cause the pump to run dry. Furthermore, such crystallization can also contaminate the conveying medium. [0004] Another example is the transportation of heavy oil or bitumen. To pump these media, the pumps used must be preheated, for example at very low temperatures, to avoid dry running of the pumps, since heavy oils and bitumen are too viscous to be pumped without prior heating. [0005] Especially for process ...
