FTI's Vertical Mag Drive

The FTI vertical pumps use high-powered, rare earth magnetic couplings to achieve transmission of maximum horsepower. This helps eliminate the common issue in mag drive pumps of lower efficiency. Carrying the advantages of mag drive pump type and vertical pump configuration, FTI vertical pumps are suitable for liquids with high pressures and high temperatures. Additionally, their NPSH can be altered thereby making them ideal for a wide range of applications. A wide variety of port sizes, impeller diameters and column lengths make the FTI vertical pumps extremely versatile.

The operating principle of a magnetic drive pump is very simple. A magnetic coupling consists of two magnet assemblies. One is the outer assembly or the drive magnet and the other is the inner assembly or the driven magnet. The outer assembly is connected to a motor and the inner assembly is directly attached to the impeller. At rest, the magnet components of the outer assembly are aligned with their counterparts in the inner assembly. When the load (torque) is applied, the coupling deflects angularly and the magnets create a force of simultaneous attraction and repulsion. This force is used to transfer torque from the motor to the impeller and is what pumps the fluid out.
