TopGear MAG - Protecting your future
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.
TopGear MAG provides environmental, human, legal and economical protection -

The Universal Mag Drive is the ideal sealing technology for critical liquid containment applications within Viking’s Universal Seal product line. It is dimensionally interchangeable with Viking's Heavy Duty bracketed and Universal Seal pumps, allowing for easy upgrade from packed or mechanical seals to sealless technology. The Universal Mag Drive’s hermetic, static sealed canister provides the highest level of liquid containment available by eliminating traditional dynamic shaft seals. It also eliminates housekeeping issues and downtime due to seal failure. This product is designed to handle a broad range of applications requiring continuous duty at pressures up to 200 PSI (14 Bar).

Viking Mag Drive® sealless internal and external gear pumps eliminate leakage and maintenance associated with shaft seals. For use with all hazardous/toxic fluids, hard-to-seal liquids and for 24/7 operations which cannot afford unscheduled downtime due to seal failure. Some models allow reversible direction of flow, and temporary run-dry capability. May be close-coupled to IEC or NEMA motors, or long-coupled with optional bearing carrier. ATEX conformity available.

The CMD series is a groundbreaking new series of sealless, non-metallic pumps specially designed for crucial liquid containment applications. This series offers several important benefits, including: 100% renewable performance with use of Viking’s recommended spare parts kit; an innovative magnet system with a patent-pending spline design that allows the magnet to self-align while floating on the shaft with no added fasteners; self-lubricating, heavy-duty bearings with patent-bearing geometry that allow dry-run capabilities; and, a unique, universal flange that allows for easy installation for both ANSI and DIN flanged systems, among other key benefits. In addition, the CMD series offers extreme flexibility, including an array of models with port sizes ranging from .25” to 1.5” (6.35 to 38.1 mm), a performance level of 100 SSU (22 cSt), normal capacity at 1450 RPM ranging from 0.34 to 16.5 GPM (1.3 to 62.5 LPM), normal capacity at 1750 RPM ranging from 0.4 to 20.0 GPM (1.5 to 75.0 LPM), a maximum differential pressure of 150 PSI (10 Bar), a maximum hydrostatic pressure of 200 PSI (14 Bar), approximate shipping weights ranging from 4 to 44 pounds (2 to 20 kg), and a maximum recommended operating temperature of 150°F (65°C).

Conventional sealing gaskets are pushed to their limits with
different applications. Typical applications are found in
polyurethane facilities, refrigerating machines and vacuum
facilities. For these applications, you have the possibility
to equip the KF 4…80 with a magnetic coupling.
The magnetic coupling serves as a shaft seal and for the
transmission of the torque. The outer rotor of the magnetic
coupling is assembled on the engine shaft and the inner
rotor is assembled directly on the pumping shaft. The
torque is transmitted through the magnetic forces between
the outer and inner rotor. Between the two rotors, you
have the split case which hermetically seals the pump.

KRAL pumps with magnetic coupling are hermetically tight, the pump station as well as the site itself stays clean. As magnetic couplings work without wear and maintenance-free, the life cycle costs are favourable comparative to conventional sealing systems.
