Problems solved by technology

However, additional measures mean additional costs and additional materials
In addition, special seals contain additional potential risks, since the seals may also fail, thereby having to worry about downtime, even though the inner and outer tanks are still physically intact

Abstract

The invention relates to a magnetic coupler, in particular to a magnetic coupling pump, the magnetic coupler has an inner rotor and an outer rotor, magnets are respectively mounted on the inner rotor and the outer rotor, and a double-walled type is arranged between the magnets A knock-out tank (6) having an outer tank (7) and an inner tank (8) with a flange portion (18), a middle section (12) and a bottom section (14) , the inner tank has a flange portion (17), a middle section (11) and a bottom section (13), wherein between the middle section (11, 12) and the bottom section (13, 14) are arranged gap (16), and wherein the inner tank (8) is connected by its flange portion (17) to the flange portion (18) of the outer tank (7). It is proposed that this gap (16) is at least partially filled with solid material (19).

Description

technical field [0001] The present invention relates to a magnetic coupling, in particular to a magnetic coupling pump, the magnetic coupling has an inner rotor and an outer rotor on which magnets are mounted respectively and arranged between the inner rotor and the outer rotor There is a double-walled separation tank having an outer tank and an inner tank each having a flange portion, a middle section and a bottom section, wherein in the middle section and the bottom Gaps are arranged between the sections and wherein the inner tank is connected by its flange portion to the flange portion of the outer tank. Background technique [0002] Magnetically coupled pumps are known and are described, for example, in DE 10 2009 022 916 A1. In this case, the power of the pump is transmitted from the drive shaft via the magnet-equipped rotor (outer rotor) to the pump-side magnetic carrier (inner rotor) in a contactless and essentially slip-free manner. The inner rotor drives the pump ...
