Overview: The TopGear MAG series offers seal-less internal gear pumps designed for handling low and high viscous liquids that are corrosive, toxic, aggressive, or expensive. These pumps ensure total containment of the liquid, eliminating the need for shaft seals and preventing leakage, thus enhancing safety and environmental protection.

Specifications: The pumps have a maximum capacity of 80 m3/h, a maximum differential pressure of 16 bar, and can operate at temperatures up to 260°C. They are constructed from cast iron or stainless steel, with a containment can made of Hastelloy C4. Bearing options include Silicon Carbide or Carbon, and magnets are available in SmCo or NdFeB for different applications.

Design Features: The MAG drive system is hermetically sealed, ensuring a leak-free environment. It includes a patent-pending integrated circulation pump for cooling and lubrication, a large gap between the inner magnet and can to minimize friction, and wet bearings made of special SiC for wear resistance. Safety systems prevent rotor contact in case of bearing failure, and monitoring options are available for preventive maintenance.

Applications: TopGear MAG pumps are ideal for handling crystallizing, hardening, toxic, and hazardous liquids such as phenol, solvents, isocyanates, and more. They provide protection against environmental, human, legal, and economic risks.

Operating Principle: The pump operates by creating an underpressure as the rotor and idler unmesh, allowing liquid to enter and be transported in sealed pockets to the discharge side, where it is pushed into the discharge line.

Additional Features: Options for heating jackets and safety relief valves are available to protect the pump during startup and shutdown. The pumps are interchangeable with TopGear GM and H pumps, and they comply with the ATEX directive for explosive atmospheres.
