Worked WELL and pump the mini split down to 175 microns fairly quickly!

Muy buena bomba de vacio

Did NOT work out of the box. Motor didn't turn, just made a humming noise. Worse was trying to get a replacement. Amazon refused to just send me a replacement in exchange for the dead one. I wasted hours in their circle of incompetence they call "customer service." For some arbitrary reason the only thing I could do was return this for a refund and then place a new order for another one. Being a business account that requires submitting for approval, and waiting for the bureaucracy to decide to place the order when they feel like it, I needed it faster than that. I found it on Vevor's website for ~$10 cheaper, and I could avoid the red tape that comes with buying on Amazon, so I ordered another one there. When its estimated delivery day came and went and I'd never received a shipped notice or tracking, I emailed their customer service. They said there was an "inventory issue." When prompted for an actual shipping estimate they canceled and refunded my order. The specs look good, I wish I could have actually got one that worked when I needed. Wasn't meant to be I guess. Amazon's customer service used to actually, ya know, service customers, now it's just stone wall, and hope the customer gets frustrated to go away. I tried pretty hard to actually get one of these, but wound up buying the 9.6 CFM Vivohome version instead.

Exelente bomba de vasio

Very nice, strong, quite pump. Plenty of vacuum. Great value for the money.

The first one arrived dead, but the seller quickly took care of the problem and got me a new pump. It took A LOT of oil changes to get it cleaned out well enough to pull a vacuum as low as is needed for the Harvest Right Freeze Dryer, but it finally did. I like this pump better than the original one that came with the freeze dryer, this one runs cooler and quieter, which is nice as it's in the center of the house.

This pump worked well until it did not . Not even a year.

This pump looks good, but unable to hook up to harvest right freeze dryer. A metric 22x1,5 female reduced to a male 1/2 inch NPT is required to make the hose connection. This can be ordered from a supplier that handles air and hydraulic fittings and hoses. My fitting should arrive today. Will add to this review after it is installed and checked out the pumps operational capabilities on the freeze dryer.

I only used it once on a heat pump system and it was fast
