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 30 GPM (1.3 to 120.0 LPM), normal capacity at 1750 RPM ranging from 0.4 to 33.0 GPM (1.5 to 125.0 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.

Magnetic drive gear pumps MDG series
Leakage free, sealless structure
The pump mechanism is the magnetic drive type. Free of leakage trouble, the pump is suitable to be incorpotated in various equipment.
Superior corrosion resistance
The wetted parts are manufactured from superior corrosion-resistant materials such as stainless steel, PPS, and PEEK. Therefore, the pump can be used to transfer various types of chemical solutions.
Long life design
Each part that is precision processed using Iwaki's original technology excels in thermal resistance, therefore does not cause pump troubles due to thermal expansion of the parts. Even when operated for long continuous hours, the pump should exhibit superior durability.

General description :
GATHER Industrie’s magnetic drive gear pump is made from stainless steel, Hastelloy or titanium and may be used as dosing pump, process pump or for laboratory service. The hermetically sealed gear pumps convey and meter in a non-pulsating manner even non-lubricating liquids such as water, salt solutions, solvents, acids and caustic solutions. As low-maintenance process pumps they can be optimally integrated into existing systems; when used for metering or dosing service they enable highly precise and reproducible flow rates to be attained. Based on the magnetic coupling and making use of new materials GATHER Industrie constantly advances the pumps originally intended for laboratory service to optimum acid or caustic solution pumps used in pilot facilities (miniplant) and for process technological applications. It goes without saying that the pumps meet the requirements of the Pressure Vessel Code and are ATEX compliant for use in hazardous areas.
