  • Great 2 stage pump
Good pump. Replaced a single stage 2 piston Porter Cable one. A LOT quieter and more efficient. Had to make an extension to mount it (see pic).

  • Breather modifications is a must!
Regarding model #4593000 You must know this before you purchase this pump! This pump works great as long as you redesign the crankcase breather. It comes with a plastic threaded breather that is glued together with a marble ball inside as it's supposed to be some kind of check valve. I would would call it useless as it puks out oil and then the pulley fan blows the oil all over the place. So my first modified breather I installed a M16 x 1.5 male thread to 5/8 hose barb with 5/8" x 12" heater hose and an after market 2" breather. It worked good for an hour and then started puking oil again. So now I have modified it with a puke tank. Let's see how this works? BTW: I used 27oz 30w non detergent STP oil label says it for compressor pump. And once you figure out how to size your drive pulley depending on the motor RPM to turn the suggested 1242 pump RPM I decided to under-drive the pump at 1228 RPM to help overheating and save the motor. Motor=3450 rpm with 4.45" pulley =1228.2 pump rpm. ... show more

  • Should have to have difficulty removing plug.
Bought in 2019 just went to hook it up, took Dewalt 899 impact gun to take out plug that lets air go to tank. The gun was on a fully charged battery, this impact gun would not remove it with 1200 ft pounds of torque, don't known if paint sealed it or what. Why would any manufacturer put it on with that kind of torque? ... show more

  • good pump for the price
This pump produces more air then the original pump for half the cost of the of replacing with standard pump and is a lot less noisy

  • Lost pressure after using approximately 20 times
I’ll give credit that while working, it wasn’t excessively loud, and I had enough air. I used it maybe 20 times over a year. And now it won’t build pressure over 60 psi. I started pulling it apart and looks like the rings on the second stage pistons were lined up, and letting air blow by. Not good quality control with something that small slipping by. Going to order new seals now to rebuild this and make sure it runs properly. ... show more
