It's only rated to 200F temperature wise. So you could probably use it for pumping from MLT->BK or fermenter transfers after cooling, but not for chilling.

Are you planning to gravity feed the plate chiller?

Temperature ranges are to be taken with a grain of salt. I wouldn't think twice about using it for boiling wort. Often times temperature ratings (or any other rating) are simply made at whatever the highest temperature that the equipment would be expected to be used in the typical application for the piece of equipment.

The housing is made from Ryton, which is a proprietary plastic made by Chevron Phillips. Here is a quote directly from the Chevron Phillips website:

PPS (Ryton) has not been found to dissolve in any solvent at temperatures below about 200°C (392°F).


It's up to you...

I've been using a Little Giant mag drive pump for a number of years without problems. I use it exactly like most use the March pumps including moving near boiling wort and hot water. The max temp ratings relate to the max line pressures which can be as high as 200 psi in some cases. We home brewers are dealing with only a few psi at most, so it's nothing to be concerned about. IMO, the LG pumps are higher quality than the March pumps. They run much more quietly and the motors have ball bearings. The owners manual says it can run dry up to eight hours without damage. That statement alone tells me a lot about the quality. Unfortunately, the LG's are a little more expensive than the March pumps from most suppliers.

weizen; I would jump on those pumps in a hot second, grab all of them ya got lucky on this one.

Also look at the LG pump at 1/12 hp vs 1/25 hp of the March pump.

What's the price of a new LG vs a March pump at $119 and higher?

Ball bearing vs a bushing motor plus twice the hp that alone has me looking as
I sold the last March pumps with the last brew system. Next system will not be
pumped with March pumps that I already decided long ago.
