ROTARY POSITIVE DISPLACEMENT PUMP WITH MAGNETIC COUPLING HAVING INTEGRATED COOLING SYSTEM

摘要

A rotary positive displacement pump for liquid medium having a main pumping mechanism driven by a magnetic coupling is disclosed. The positive displacement pump includes an integrated, positive displacement, circulating pump configured to provide a controlled medium flow through the magnetic coupling from a discharge side (0206) of the main pump back to a suction side (0205) of the main pump.
