Excellent purchase
I purchased this pump to replace a failing harbor freight 60 gal. 5 HP 165 PSI Two Stage Air Compressor pump. It was the best deal I could find that was as close to my original 165 max psi, 15cfm pump. I am very pleased with my purchase, especially at this price point.
I'm not sure if my other pump had been slowly failing for a long time, if it was just a poor quality pump from the get-go, or if this pump is just much better, but it fills extremely quickly, much, much faster than my other pump, from zero to 120 in less than 5 minutes. Recovery is also super quick, especially since I don't set my pressure to max, in order to save wear and tear on the system.
Installation was fairly straightforward. I had to replace the pulley on my electric motor, as this pump uses a double B belt and my original pulley used a single A belt. Since my motor is a 3450rpm, I needed a 4-inch double B pulley to get the rated scfm out of the pump.. I picked up one at my local ag supply store, along with two B51 belts. The more challenging part of the install was adapting the air supply line to my tank. This pump uses 3/4 O.D. compression refrigerant line, and comes with a funky (metric?) thread compression nut. The good news is that if you can find a small piece of soft copper tubing (I had to buy a chunk from my local HVAC company), you can then use standard compression fittings to connect to your tank. I probably spent an additional $100 on parts, including the $60 pulley, bringing my total cost to resurrect my air compressor to less than $300.
