MXBAOHENG Automatic Lubricating Oil Pump Digital Numerical Control Electromagnetic Lubrication Pump Oiler CNC Oil Pump Lathe Oiler (1L)

I wish I had paid more attention to how the factory oil pump was wired up before I removed it. My machine suffered a minor fall while moving it and the pump caught the brunt of it (thankfully not anything irreplaceable). While cleaning it up before putting the machine to use I removed the pump and motor controls as I would be replacing the factory motor starter with a VFD controller as I don't have 3 phase at home. I assumed the little pump was a tiny 3 phase motor.Nope! I didn't realize until after I had stripped it out that the transformer actually produced 120V single phase power from 3 phase specifically for the pump, and it only and automatically powered it when the motor was on.I also didn't realize that this unit doesn't have any sort of power switch or on button. It really is designed to be a direct replacement.Instead of wiring in that transformer (which I think I'll repurpose as a shop use electromagnet) I just picked up a $15 inductive switch here on Amazon. I added a length of appropriate wire from one of the 3 motor leads and looped it through the inductive switch body and back to the supply line in that box and now this works just like the factory one, running only when the motor is on. Plenty of power for the 6 port oil distribution system, including a 2' rise from this pump to the top of the column. Time will tell how it holds up, but it's a very simple design that should work great.My ONLY complaint is that the float in the back left corner which detects the oil level is set too high, appreciably reducing the effective capacity of the tank. You need over 1" (25mm) of oil before it will pump for more than about 1/2 second before the alarm goes off complaining there's no oil. I'm glad it won't try to pump dry, but it should be set at about half the distance from the bottom that it is (not directly on the bottom is good so you have warning before starting a job).

The product works great. I did have a failure of a part after a couple weeks but the seller sent a replacement board and pump. Good customer service.

Wired it up and it had great oil pressure !!! Very happy with my purchase .

I had problems wth the first one they sent me as it would overheat and then have to reset, it works good as long as you are not trying to pump oil with it for long periods, Also the display is going out after 3 weeks of use
