EnglishMARCH MASTER GEAR
Horizontal, self-priming, single-stage, magnetic driven rotary positive displacement pump in close-coupled design made of stainless steel.
MARCH MASTER GEAR series magnetic driven gear pumps are gear pumps in monoblock design with magnetic drive and operate completely without mechanical shaft sealing. Power is transmitted by a force-locked connection to the hydraulic section by strong NdFeB permanent magnets without contact. MARCH - Magnetically coupled gear pumps comply with the highest standards of quality, economy and reliability when conveying a wide variety of liquids.
