Rotary piston pump
The novel rotary piston pump operates with permanent magnets, which are arranged at the vertices of a piston rotor. In the pump housing coils are arranged, which generate a rotating magnetic field with which the piston rotor is driven. As a result, a seal-free drive is realized, which dispenses with the components eccentric and gear transmission.
Seal-free design
Long service life
Hermetic tightness over the life of the product and bypass interactions between the fluid and the seals. Due to the elimination of the sealing joints, the new technology is particularly suitable for use as a blood pump.
The new rotary piston pump works with permanent magnets arranged at the corner points of the piston rotor. In the pump housing, coils are arranged which generate a rotating magnetic field which in turn drives the piston rotor. This results in a seal-free drive that does not require the eccentric or gear drive components.
