6 Advantages of ANSIMAG Sealless Magnetic Drive Pumps

When you have to contain hazardous, corrosive or valuable fluids, a sealless magnetic drive pump is ideal. This is a common need for chemical processing plants and other applications dealing with difficult liquids. ANSIMAG, a subsidiary brand of Sundyne, offers an exceptional line of sealless magnetic drive pumps that are lined with EFTE (Ethylene Tetrafluoroethylene) for optimal performance and dependability.

Here are 6 advantages of ANSIMAG Sealless Magnetic Drive Pumps:

1. Safety

First and foremost is safety. This is of paramount importance when handling chemicals and other hazardous fluids. Any leaks from the pump system could be disastrous for worker safety and environmental concerns. With no seals to potentially cause weak points and EFTE lining, leaks are prevented and safety is improved.

2. Leakage Elimination

As we mentioned above, the ability to eliminate leakage is a primary advantage of sealless magnetic drive pumps like the ones produced by ANSIMAG. There are no gaskets that can weaken and deteriorate over time. There are no mechanical seals that can fail. This provides primary containment of the process fluid within the pump system and prevents it from leaking into the exterior environment. Whether the liquids are hazardous or simply valuable (or both), eliminating leakage is a major advantage.

3. Energy Efficiency

ANSIMAG sealless magnetic drive pumps are more energy-efficient than its competitors. The innovative rear casing generates no eddy currents. This eliminates heat generation and reduces energy costs during operation.

4. Corrosion Resistance

All wetted parts of these pumps are specially molded EFTE components. The lining safely handles a wide range of corrosive solvents up to 250°F (121°C). The fully encapsulated magnetic drive hermetically seals the inner magnets. This keeps the drive system completely isolated from process fluid, which is very important in chemical processing application. The Kevlar-fiber reinforced vinyl ester shell provides exceptional reliability and corrosion resistance.

5. Noise Reduction

ANSIMAG sealless magnetic drive pumps run smoothly and relatively quietly compared to many other pumps. Reduced noise level is preferred by pump operators and plant neighbors. Noise pollution with some pumps can sometimes be just as detrimental as leaks.

6. Reduced Maintenance Costs

Without seals to replace or maintain, your plant can benefit from reduced downtime and fewer costs related to replacement gaskets or mechanical seals that other pumps require with regular shaft seal maintenance. There are no leaks, no emissions and no maintenance or repair costs related to the seals.
