EnglishMarch Master Gear Pumps
Magnetic Driven Gear Pumps
Product description
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 through 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.
