Reliable use of canned motor pumps in the chemical industry
Canned motor pumps guarantee maximum safety for man and the environment in the various production processes of the chemical industry. Often designed for extreme conditions, they are used whenever liquids and gases have to be pumped at extreme temperatures and under potentially hazardous conditions. The pumps offer complete reliability – even at the highest pressures and performance levels.
Description of the magnetically coupled pump
Magnetically coupled pumps are a combination of conventional pump hydraulics with a permanent-magnetic drive system and a three-phase motor. This system uses the attraction and repulsion forces between permanent magnets in both coupling halves for contactless and slip-free torque transmission. Between the two coupling halves equipped with magnets is the can separating the product space from the surroundings.
Description of the liquid ring vacuum pump
A liquid ring vacuum pump is a rotary displacement pump in which an eccentrically mounted rotor with fixed blades pushes a liquid against the wall of the stator (housing). The liquid takes the form of a ring concentric to the stator and forms together with the rotor blades several spaces with changing volumes. The pumps can be manufactured conventionally as well as hermetically sealed with magnetic drive or canned motor drive.
