Customer Reviews for VEVOR Recirculating Pump, 93W 110V Water Circulator Circulating Pump NPT 3/4" w/Brass Fittings, 3-speed Control Recirculation 9.5 Gpm RS15-6 for Electric Water Heater System

Easy installation. Works well to boost our boiler circulation to the second floor. Caution - in a hydronic system the auto start function does not appear to work correctly. Consider wiring directly to the boiler pump so it shuts off when the heater does.

It works but you better buy the connector suggested by Amazon to buy together. this one: https://amzn.to/3iDkPTU. Because this pump has both ends as male, you'll need this connector. I looked something similar at my local hardware store without luck. Make sure you install plastic seals on both sides of the connector and use enough teflon tape. When working the pump is almost quiet, you really need to focus to hear something. It's still cheaper than buying the Amazon suggested over $230-250. I use smart things to control it.

Used for circulating water from a hot water heater

I'm using this pump along with a plate heat exchanger to heat my hot tub, working great so far, only time will tell.

Good product,and price.Not installed yet,but tested it,and seems to work fine...very quiet.Shipping reasonable time...looking foward to buy more things soon.

The pump body fittings were advertised to be "hose"... They were not American hose threads ! The adapter got it from pump to 1/2" pipe, so that's the route i went... Had in mind just using hose to go from here to there, but nothing doing...

Makes a great hot water recirculation pump! I run it on low speed and plugged into a timer. Love it and best of all made my wife happy!!

Vevor RS 15-6 pump curve. I asked the manufacturer for a pump curve so I could verify that these would work in my in-floor radiant heating system...and was told that none existed. Not wanting to buy 10 of these only to find out they were not suitable for my application, I bought 1 and made my own curve. I used a cheap rotameter 100 - 1000 l/h and a cheap 15 psi pressure gauge. Not lab quality, but should be reasonably close. Also, not full flow range, but it is in the working range that I was looking for. The 3 separate curves correspond to the 3 settings on the pump. Manufacturer claims a max head of 6.5m (which seems very close to my test data) and max flow of 37 l/m (which I think if optomistic...extrapolating my pump curve would indicate the max flow is probably closer to 25 l/m. Haven't installed this yet, but quality seems good and mine came with adapters to 3/4" MPT as advertised. Ironically, the manual that came with this does have 33 other pump curves in it, but does not appear to have one specifically for this model.

This worked as a cheap replacment for my hot springs hot tub
