My 2 stage pump is rated at 1150 rpm’s per minute,but I got the pump set(by putting right size of pulley on the motor) to running 850 rpms, which is it’s suggested minimum,and a good pump run low rpm’s you can get 30 years usage out of if maintained properly…

SPEED KILLS….Take an automobile for example, it can go 120 plus miles per hour, but if you keep it at that speed constantly it will wear out or blow up a lot quicker than if you slow the car down and run it at 55 miles per hours during it’s life span….You get a lot more life and better performance on the car. On reciprocating compressors the lower speed you can run the pump the better and longer wear you will get from it, but it cannot be ran lower or higher than recommended. The motor you have is rated at 3.1 horsepower and will literally burn that pump up after a little use.Īll pumps have a minimum and maximum speed at which they should turn, and they pair them up with a motor and/or the proper pulley size*(is very important) for the speed of the pump. I could not find the actual cfm info you asked for the motor that is supposed to be sized up with the pump model you have should only have a max of a 1 1/2 horsepower motor on it. SCFM is closer to just simply conning the purchaser to believing they have something they don’t.Ī lot of good content here PCBEACHRAT. CFM can be figured a lot closer to true regardless of altitude, temperature, ambient temperature, humidity etc. For this, I cannot answer, but this will at least explain the truth about scfm.īasically you can search the net and come up with many many descriptions of how scfm came about or figures out.

Now I have shown you how to get true horsepower, but the scfm thing is about as real as Rumpelstiltskin, and is something that cannot be truthfully answered. Here is a quick explanation of SCFM.Ībout the 6th paragraph on the following link tells you more about scfm being calculated,and that it means total different calculations depending on the certain conditions,temps etcetera in the area the compressor is operating from. Let me look for the proper article on this…įirst here is a very important article, again on true ease read this to understand true horsepower better. No One can calculate scfm by using these factors in different regions,so scfm is totally useless and means nothing. SCFM has nothing to do with true CFM,and can only calculate at certain altitudes,certain ambient temperatures,certain regular temperatures and many other factors. Next I will post an article about scfm which is an imaginary scenario compressor manufacturers use now days which is basically an imaginary calculation to use.

On this calculator keep the efficiency rating at 65% for this is about the most that air compressors run at full load. I will see if this link will paste on how to calculate TRUE HORSEPOWER. The original specs for this compressor was 10.8 SCFM 90PSI – I’m trying to figure out the effect on this having had the compressor head changed.įirst your true running horsepower on that motor is just barely over 3 horsepower. The motor is 240v 15amp listed at 2.96kw (4hp). Its listed as having a Speedaire 4B247 compressor head but the reality is that it has a Speedaire 2Z499 compressor. The compressor is marked up as a Speedaire 4B228B. Only when I got home I realized that it looks like both the motor and the compressor have been replaced at some point in their lives.
