    AHH I get it now so my compressor is rated to operate at 11 bar and 16.5 test pressure makes sense now thank you for clearing that up for me you learn something new every day

    So I got testing the compressor today and it doesn't do the job takes about half a minute to empty half a tank and any pressure after that is useless for blasting so just wondering if I put another 50ltr tank on it would that make much difference?

    Ive had two ingersoll rand compressors and both have had abac pumps, but only found that file when i purchased my second one as really wanted to know the output of the pump and like you said earlier the model number doesn't seem to get any results only more second hand ones for sale

    Well at least we got to the bottom of it looks like 7cfm on the compressor do you know if these big compressors can run for long before they over heat since you've had a couple yourself my wee cheap compressor £100 job does three cycles then it shuts down for 20 mins to cool down but it does have 9cfm shocking it's half the size of the old girl I appreciate all the help :)

    Does the motor size match the one listed for the pump?

    Is the pump rotating the correct way to cool the pump properly?

    I would say from looking at your first picture again, it looks like it doesn't have the original belt cover fitted, the direction for the pump to rotate on mine is marked on the outside of the cover

    The two Ive have have been bigger and haven't had any problems running for prolonged periods.

    Just had a quick look online and found one picture that shows the direction to be anticlockwise when looking at the pulley. Not sure if it the one for yours but think air flow should be forced over the pump.

    Now that you have mentioned it what your saying makes sense I wouldn't even of picked up on that I seen the big fan cooling wheel and thought that should keep things cool but as you said it's not actually at it full potential because it just blowing air all over the place I'll see about getting a cover for it and have a look at her tomorrow to check the direction of the fins on the cooling wheel if that's what it's called to see if it's blowing air at the compressor or away from it your a world of knowledge carbon :) I might end up with a usable compressor at this rate I did notice a air leak under the pump looks like a black bicycle brake cable didn't get a chance to have a proper look at it until tomorrow

    I wouldn’t worry about getting a specific cover as there are plenty of compressors that only have a wire guard, just check which direction the pump is running
