VEVOR 93W Recirculating Pump, 3 Speed Control

This pump was a direct replacement to a hot tub circulation pump that cost between $175 to $250 to replace. It needed basic pvc and brass pieces to complete and it slid right into my tub perfectly. I run it on the lowest speed. Speed 3 is pretty decent output, but for a 4 man tub, speed one is sufficient. Still better output for heater and ozinator bubbler than the old one. $31.00 vs. $200 and up? No contest. Great components and runs absolutely silent. I had to add a ground wire terminal to the body by using existing screw on motor body cover, but it is double bonded, and double grounded.

I purchased the RS15-6SB variant Feb 26, 2023 and it's almost Dec 2024 now. This pump has worked satisfactorily for ~10 months & is still going strong. In my application it recirculates domestic hot water between oil boiler, wood boiler and solar systems tanks / exchangers. It sees DHW ranging in temperature from ~100°F to ~150°F at 30-50 PSI. I'm planning to purchase another, possibly the S15-9SR which can be set to switch on/off automatically.As seen in my three photos, my pump came with adaptor fittings to sweat 1/2" copper pipe.For the price and considering the other pumps available for this purpose, you can't expect more. To say the least I'm satisfied with this Vevor product. If it was rebranded, it could probably be sold for twice as much.

Maybe it's a serviceable pump. I don't have any way of telling yet. It comes with, what appears to be 3/4" NPT input and output threads and includes 2 high quality brass 3/4 to 1/2 adapters. Unfortunately, on one side of the pump, the threads are cut so poorly into the casting that the coupler won't attach (and neither will anything else I've tried). It appears they were either cut out of round or simply not deep enough. Since I can't return it I'm going to try fixing the thread with a dremel. If that works, I'll review the pump itself and perhaps switch to 2 stars. As-is, it's not usable.

Works as intended, exceeds expectations. Was easy for me to install. I bought it to circulate water in my chicken water system to help prevent frozen water when the temperature drops below freezing. I like the 2 different speed options. We recently had near zero temperatures and the pump kept working, no problems whatsoever. I would buy again if needed in other situations, great value for the money.

Works as described but a little loud

If you need a low powered pump that’s quiet this is a good choice. This is not a powerful pump, but works well. Don’t know about longevity yet. The auto on feature does a good job cutting pump on when water flows.There is confusion about the threads. These are straight threads meant to be used with a washer seal, unlike tapered npt threads that seal when the threads tighten.3/4 female iron pipe fittings FIP will screw on the pump with no problems. They seal with a rubber washer.

Bewares. I using in the United States, don't buy this one. Look for a pop with NPT threat. This one comes with G thread used in Britain and Europe. Standard NPT thread will not work on the connections.

Put this on my hot tub and it goes out after 2 months
