Type GML is an internal gear pump with magnetic coupling. The pump has only two moving parts, the impeller and the rotor.
In this case, the feed wheel is taken from the driven rotor.
The delivery liquid is drawn into the remaining free space between the tooth flanks of the delivery wheel and the rotor. The crescent-shaped sickle opens up the gaps between impeller and rotor, while the fluid is moved in pressure side. It creates a uniform flow rate without pulsation. The pump is always equipped with an easily adjustable safety valve (bypass).
The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside. An internal circulation current dissipates the heat generated by the eddy current losses.
The bearing of the pump shaft is carried out in SiC plain bearings, the drive shaft is mounted in permanently grease-lubricated ball bearings. The position of the nozzle is both angled and opposite possible.
