💪 Powerful and Reliable: MASTERCOOL 6 CFM Single Stage Vacuum Pump (Model 90066-B) Review

AFTER 5 TIMES IT WILL NOT HOLD VACUUM AS IT WAS NEW. AND AFTER A FEW SECONDS AFTER THE SUCTION TURNS OFF, THERE IS NO FEELING. I NEED INFORMATION FOR THE EXCHANGE

We bought this pump to run our cluster for our cow. They're not as heavy as the pumps my husband uses for HVAC work, but the price was a lot less. He did the job we had to do. We only used it for a few months prior to drying our cow but will be using it again shortly after calving season. I will update this review as needed.

I've used these pumps for years, they work great at creating deep vacuums. I use several of these with 1/2 vacuum hoses in the same system. Pulls up to 500 microns before you know it. I use mine for a year then throw them away with new ones and for the price it's worth it. The pumps are still running after a year and you can reverse the top seals in the pump to extend its life.

This is my second compressor in 4 years. I milk up to 17 goats. I ordered this and got 3cfm instead of 6cfm. While I'm waiting - I'm milking by hand! I had to send back to get the right one. Looking through my order details, I see that part of my order is a $200 listed item (which I didn't order) that didn't ship. NOW I also need to do some research to make sure I won't be charged. POOH!

Good lightweight pump for the money. It pumps up the system pretty quickly. The only thing I don't like is that this pump is made of cheap materials. You can't throw it around like more durable pumps. The metal cover over the motor fan is very thin and easily damaged as mine did twice. It should be kept in the box between uses or during transport. I like the fact that it's lightweight, bleeds the system quickly, and doesn't cost much. Time will tell if this was the real deal. It has worked well
