Abstract (en)

The pump (1) has a guide sleeve (15) passed through openings (13, 14) formed on opposite sides (11, 12) of a magnetic return element (10). A ball-cap-shaped pump chamber (6) formed by a portion of the sleeve is passed through one opening. A portion of the chamber facing away from a stator (17) is passed through another opening. The sleeve and the stator are made of magnetically conductive material and magnetically disconnected from each other by an insulator casing (18). The insulator casing is formed by a portion of the guide sleeve and made of magnetically non-conductive material. The pump comprises a lubricating layer made of PTFE or a molybdenum disulfide layer.
