Product Description:

The Johnson TopGear MAG range is a leak proof internal gear pump for toxic or hazardous media. TopGear MAG is for low and high viscous liquids which are corrosive, toxic, aggressive or expensive. Total containment of the liquid inside the pump is achieved using a hermetically sealed can, which isolates the liquid from the surrounding environment. This eliminates the need for shaft seals and the associated wear and leakage that would normally be experienced. The Magnetic Drive pumps are therefore not only environmentally friendly – they also contribute to improved safety in chemical and process plant environments. Complying amongst others with the “ATEX” (ATmospheres EXplosibles) directive, magnetic drive pumps make an important contribution to health and safety of process plants.
