Vacuum tables and Pumps

Not really but it’s 1130 and freezing and I’m in my pyjamas.!!!

Hey Eugene,

:cold_sweat:

Get your vacuum pump to run must mean something to you :slight_smile:

Think I would do the same for a vacuum table :slight_smile:

So connect neutral to the red and yellow and live to one of the others and earth to the chassis

I’m not going up there again tonight though

yes, earth to chassis, not to forget.

I would say exactly this way, but you have to carefully try which of the two for “L”.
I don’t know if you can see if it runs in the right direction.

There are two openings with arrows, one opening has a grill on it I assume that this is the suction

Reads like a classic exercise in asynchronous detective work with someone in the UK.

And me too, I’m already one hour later, I’m UTC+1! Good luck!

I wired it up this morning and to make it run following the arrows on the suck and blow the positive wire went on the centre connection (which is the blue wire on the photo). In the video of the pump on ebay it sounds loud but in reality it is quieter than my shop vac. I’m very happy with it, let’s see how long it lasts. Once again thanks for the help in figuring it out.

Hey Eugene,

happy to hear your success. :slight_smile:

This is because it is a type of induction motor, like I mentioned above. They have no sparks-emitting carbon-brush commutators and are therefore quiet.

I have a very similar problem. can someone help me?

I have 3 vacuum pumps that came with my cnc. I have an OMNI CNC 1325.
I have the motors hooked up but the breaker tripped after a minute of running. I grabbed my FLIR camera and the pumps all were over 200 degrees.


can someone please help!

The picture above says it all. There should be a connection diagram on the wiring box somewhere. I have an ABB 4HP regenerative blower for a vacuum setup and power hookup was totally not intuitive because they use the same frame terminals for many different models. Single and 3 phase, differing voltage and there may also be some extra wires in the box that go to temp sensors ( or not). you really need to have a product specific diagram. It is possible to figure it out and you may guess correctly, but wiring it wrong can have really bad results. It is not worth guessing. I have been a power and motor guys for 30 years and I backed out and went and found a manual, glad I did cause it was not what I expected, even brand new in the box from the mfg.
