Sealless Pump seeker

[mu85922]

can someone recommend for me one type/make of sealless pump which can be used in a petrochemical application such as polypropylene plant. Whow does it seal without a seal? what implications that might have if any.

There's a lot of different types of sealless pumps, including diaphragm pumps, peristaltic hose pumps, mag-drive centrifugal pumps and canned pumps. Very different pumps for very different services, but I've used all but the peristaltic hose pumps in different services before, including petrochemical (a polyethylene plant, actually). What are you looking for specifically, to narrow it down a bit?
