Design
SN Magdrive is an internal-bearing, triple-screw, self-priming, sealless screw pump with magnetic coupling. The magnetic coupling’s containment hermetically seals the pump. Hardened and polished screws run inside an exchangeable casing insert. Idler screws are hydraulically driven and axial thrust is fully balanced hydrostatically. A liquid-lubricated groove ball bearing fi xes the drive screw in place. The pump’s magnetic coupling and suction chamber are connected to each other via a return bore.
