Differences between mag drive pump manufacturers?

[YungPlantEng]

There are several mag drive pump manufacturers our company uses across several sites (Iwaki, Innomag, Ansimag, Finish Thompson)...

Do all these manufacturers provide some sort of niche or are they all just built to the same ASME or ISO standard? What are the primary differences between these pumps? I can never get a straight answer from vendors.

The primary differences are the company that manufactures them.

In my experience, Finish Thompson makes some smaller sizes (below ANSI) that others don't.

In the mag drive world there are several different option. In general I always describe them as 3 categories. lighter duty, Medium duty, and Heavy duty.

In the lighter duty space these would generally be thermoplastic pumps (polypro, Kynar etc). You see these a lot for smaller flow rates and cleaner materials. Usually max out at a 2" pump.

In the medium duty space there are alot of options as far as a manufacturer goes. In general these are the ansi Etfe/Ptfe/PFA lined mag drive pumps. Usually they have an Etfe with some impregnation for the impeller that can cause some issues with various acids. In this space most manufacturers will have one/two tweaks to their pump to make it a little different but in general these are very close to the same technology. These do well with some slight solids but best to apply them on clean fluid. There are also some ISO versions on the market in this same design and technology.

In the heavy duty space you get into thicker liners of with solid PFA impellers as well as alloy Metallic mag drive pumps. Some in this category handle up to 30% solids content and can handle fluids up to 350C such as hot oil and other molten products. Usually these have various options and are a great alternative to double sealed pumps for aggressive media.

let me know if you have any other questions or if I can elaborate on this topic. I have been dealing with Mag drive pumps for quite some time
