Magn\u0113tisk\u0101s piedzi\u0146as s\u016bk\u0146u pamat\u0101 ir centrb\u0113dzes s\u016bk\u0146i, un griezes momenta bezkontakta p\u0101rnesei tiek izmantota magn\u0113tisk\u0101 sakabe. Tie ir jauni centrb\u0113dzes \u0137\u012bmisko procesu s\u016bk\u0146i bez v\u0101rpstas bl\u012bv\u0113juma, ar pilnu bl\u012bv\u0113jumu, bez nopl\u016bdes, iztur\u012bgi pret koroziju un bez pies\u0101r\u0146ojuma.<\/p>\n

Introduction to magnetic pumps Magnetic drive pumps are based on centrifugal pumps and use magnetic coupling to achieve contactless transmission of torque. They are new centrifugal chemical process pumps with no shaft seal, full seal, no leakage, corrosion resistance and no pollution. Magnetic pumps are usually composed of motors, magnetic couplings and centrifugal pumps.
