FLOW, in gallons per minute, equals speed or RPM, the more flow the faster the motor will run, up to it"s rated input. If you try to put more volume into it than what it"s rated for, it will still work but trying to squeeze in extra flow will cause it to heat up. If you put less gallons per minute of flow into it than it"s rated it will just run slower. If pressure is the same, it will still have the same power-just at a slower RPM. Pressure, in Pounds per square inch,(PSI) equals twisting power or torque, less pressure is less power ! Exceeding the manufacturers pressure rating could cause the motor to blow seals. Check your motor manufacturers ratings, it will have a Displacement rating or cubic inch"s of oil per RPM, or how much oil is needed to turn 1 RPM. multiply that by the desired RPM to get the volume of oil needed to turn the desired RPM. There are 231 cubic inches in a gallon. Divide your cubic inchs by 231 and you have the gallons per minute needed (in pump size) to run the motor the desired RPM. Your motor will have a "Torque rating" at a certain pressure..say XXX inch pounds at 1000PSI, (Do that by 1.5 if you are going to need 1500 PSI etc.) Torque times RPM divided by 63025 equals horsepower. T x RPM /63025 = HP

Today's Featured Article - Picking Corn - by Rick Nikolich.

He wanted to get the rest of his corn in by the next day (Christmas Eve). We had about an inch of new snow on the ground and single digit temperatures. So in the bac
