GRI Mag drive pump

[barleywade]

I am looking at a few alternatives to the March pumps and was wondering if this pump would be a good one. The model is the 14110 GRI Mag Drive Pump, 570 gph, .5 amp, 6.25 lbs with these specs for $149.

Pump impeller driven via a magnetic coupling so no shaft seal is needed. Pumps should be used where flooded suction exists.

Features include TEFC motor, ceramic pump shaft, EPT/EPDM O-rings and Ryton body. Motors are thermally protected 115V, 50/60Hz.

Material in contact with solution:
Body – Ryton
Impeller – Ryton with epoxy adhesive.

Other components:
Impeller bearings – resin impregnated carbon
Front thrust bearings – glass filled Teflon
Rear thrust bearings – ceramic

Is it food safe? What are the temperature limits for the materials? LInk?

Here is the link for the pump. I am contemplating this one or the LG 3md hc for $150.

according to these links, Ryton appears to be safe for hot liquids and food safe:

According to the GRI page they are good to 250* if I read it correctly.

This would be my first pump, does anyone have any thoughts on this one compared to the LG 3MDHC for $150?

Either one is fine.

Well, one is a closeout. That would make the decision for me. I'll want the company to honor a warranty.
