Can I use this pump for my CL (PICS)

[Gundo5000]

Guys, my friend gave me this pump but couldnt remember where he got it. He does a lot of maintanence over the years. Would it be okay for a closed loop?

Is it safe to use?

What do you think it will pump in gph?

Anyone ever used one?

I would not use it, not even in "self defense".

Seals are not designed for salt water and are not replaceable.

This is a note on the distributor site:
http://www.electricmotorwarehouse.com/tiny_might.htm

Attention: Due to the high failure rate of the Tiny Might pump we recommend replacing your Tiny Might pump with the larger more dependable Iron Might Pump. Spa manufactures no longer use the Tiny Might or Lange pump for circulation due to the fact the failure rate is very high

Note: Tiny Might pumps seals are very susceptible to damage from pool chemical imbalances. Be sure to keep your ph levels at the correct balance. Failure to do this will result in premature seal failure, which will damage the motor bearings.
This is true with all the small circulation pumps such as the Lange and Grunfos pumps. They are designed to operate at 10 to 15 GPM @ 2 to 3 PSI. Motor damage as a result of this is not covered under warranty. It is the end users responsibility to maintain the proper water chemistry. The seals are not replaceable

ya but you pool and spa is alot different from the salt water tank .. the chemicals in a pool will distroy the rubber seal .
if it was me id use it

[jdieck]

Note that even shafted pumps supposedly for Salt water like Dolphin and Barracuda etc. had lots of problems with their seals until they specially re-designed them for salt water by using an special silicon steel alloy.
No rubbers, no 304, 308 or 316 stainless steel, no graphite

By the way insure you have no cavitation by installing a large diameter pipe on the inlet, specially if you use a shafted pump (rather than magnetic driven) otherwise vibration will significantly shorten the seal life.
