Patent ID: 8596997

Claim:
A membrane pump ( 1 ) comprising: a pump housing, a membrane ( 4 ), which is mounted to the pump housing and delimits a pump chamber ( 8 ) inside the pump housing, an inlet ( 5 ) for feeding medium into the pump chamber ( 8 ), the inlet ( 5 ) having a first non-return valve connected thereto, an outlet ( 6 ) for discharging medium from the pump chamber ( 8 ), the outlet ( 6 ) having a second non-return valve connected thereto, and actuating means ( 7 ) for moving the membrane ( 4 ) back and forth between a first and a second position in an axial direction, wherein the membrane ( 4 ), the inlet ( 5 ) and the outlet ( 6 ) are arranged in a first exchangeable part ( 2 ) of the pump housing, the first exchangeable part ( 2 ) being detachably connected in the axial direction to a second part ( 3 ) of the pump housing, in which the actuating means ( 7 ) is arranged to form an integral structure encompassing both the membrane ( 4 ) and actuating means ( 7 ), the membrane ( 4 ) is detachably connected to the actuating means ( 7 ) by a magnetic coupling, which comprises a first magnetic coupling part ( 9 ) fixed to the membrane ( 4 ) and a corresponding second magnetic coupling part ( 10 ) fixed to the actuating means ( 7 ), and said first and second magnetic coupling parts ( 9 , 10 ) are detachably fixed to one another to directly contact one another.
