TG G-range, for
general purpose |
TG H-range is for high demanding application |
The TG L-range is for low viscosity, high volumetric efficiency |

|
|
| TopGear MAG is a range of leak-proof internal gear pumps 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 on process plants. |

| Features/Benefits |
Applications |
| • |
MAG drive - hermetic closed pump system - Ensures clean, safe and leak-free operating environment |
TopGear MAG is the perfect solution for avoiding leakage of liquids which may
jeopardize health or environment or for liquids which are just problematic to
seal off.
• Crystallizing and hardening liquids
• Toxic and hazardous liquids 
Example of liquids:
Phenol, Solvents, Isocyanates, Sodium hydroxide, Epoxy resin, Paint, Glue, Ink,
Fuel Additives, Caustic solutions, Sugar solutions, Oils, Bitumen, Alcohols |
| • |
Unique solution for forced circulation and cooling - Guaranteed cooling and lubrication of
magnetic coupling and bearings independent of operation
pressure and liquid viscosity |
| • |
Large gap between inner magnet and can - Minimizes friction losses when pumping high viscous
media giving low heat generation, long durable
operation |
| • |
Wet bearings of special SiC - Can handle low viscous media and is extremely wear
resistant |
| • |
Hermetic can material of Hastelloy C4 between the
magnets -Safeguards durable operation and long life
time |
| • |
Monitoring options - Possible to install sensors to monitor temperature, pressure
and vibrations for preventive maintenance actions |
| • |
Safety system for bearing failures - No risk for leakage and contamination |
| • |
Heating jackets and safety relief valves |
| • |
Back and front pull out - Less maintenance downtime |
| • |
Interchangeablity |
