Abstract
A description is given of a corrosion-resistant sleeve (7) for magnetic rotors (20, 21) of pumps, in particular for plastic-encapsulated magnetic rotors in centrifugal pumps, which effectively protects the rotors of laboratory centrifugal pumps from corrosion and premature wear.
Claims7
A pump having at least one magnetic rotor, said pump comprising:
- a corrosion-resistant sleeve and plastic cover, wherein said corrosion-resistant sleeve is disposed within a chamber and said plastic cover is sealably placed over said corrosion-resistant sleeve to tightly surround said magnetic rotor with said plastic cover and said corrosion-resistant sleeve sealing said magnetic rotor from a delivery medium, said magnetic rotor driving a pumping means of said pump.
