Controlled Twin Piston Oil-Less Vacuum Pump 5.5CFM 3/4HP Regulator/Gauge Hardware Kit Pressure Control Oil-Free Clean No Oil Mist

I bought this to use with a single cow bucket milker from DeLaval. I connected it to a 7 gallon air tank from Lowes to use as a balance and water trap (incoming line connects to the drain port and out to the vacuum pump connected to the top). It was less than half the cost of buying a system with a liquid trap already included. We are using an older DeLaval bucket milker with an Interpuls LL90 60:40 pulsator and everything works as expected. You do have to be quick to attach to the udder when you open the milk flow valve on the claw, otherwise there isn't enough suction to attach after a few seconds. For our use, I think this is a great setup so far. I can't speak to longevity yet, but I hope to use this for the foreseeable future.

I have been a GAST rotary vein pump user for decades for CNC to vacuum gluing needs. Now I'm in a smaller home shop where space is tighter so noise levels are a big deal. My GAST pump was the loudest tool in the shop near deafening. This diaphragm pump is extremely strong, vacuum bag clamping has been working flawless, nothing has let loose on the CNC for wood working holding application and its so quiet compared to anything else in the shop I often forget its running. 2-3 months into its use and its kicking butt. LOVE this pump 5 stars

It works great. I'm getting another one.

This pump SUCKS.... in the best way! I have never milked my cow as fast amd easy as I do with this pump. It was delivered early and the seller went above amd beyond.
