Sealless Magnetic Coupled Vertical Self-Priming Side-Channel Pumps Type SMV our ution contrib for mental environ ion t protec

General pump shaft The side-channel pumps SMV are self-priming and operate more economically (better efficiency) than normal centrifugal pumps when handling low flows and high heads. SiC-rings suction and pressure disk Therefore these side-channel pumps can solve many pumping problems in chemical and petrochemical applications. They can be used for almost all liquids which are free of abrasive solids and of suitable viscosity. (Application limit for self-priming design is 100 cSt). The vertical side-channel pumps are suitable especially for tank farms with underground storage tanks with a diameter...

Sleeve bearing Magnet coupling The magnet coupling consists of the driven rotor and the drive rotor. The rotors are fitted with single magnet elements. Magnet material is Samarium Cobalt with unlimited life time. The stationary wear resistant SiC-sleeve bearings are shrink-fitted in the sleeve bearing housing and form together the sleeve bearing unit. This unit is placed in the bearing housing and fastened by inner hexagon cap screws. The unit is interchangeable and easy to replace. Pumps in operation generate eddy currents in the metallic containment shell which heat up the product in the gap...

Relief valve power consumption discharge pressure without relief valve with relief valve adjusting bolt suction discharge flow Relief valve Performance characteristic Contrary to centrifugal pumps, the side-channel pumps generate a steep head rise and an increased power consumption at lower flow rates. Power consumption and discharge pressure reach the maximum at closed discharge. To protect discharge pipes and to avoid overload of the motors and unacceptable temperature rise in the pump, an additional relief valve can be fitted to the SMV-pumps. Installation at site, suction piping During the...
