7.5 - 10 HP Replacement Two Stage 4 Cylinder Air Compressor Pump with Head Unloaders

Brand new 4 cylinder cast iron two stage air compressor pump. This is a 7.5 - 10-horsepower pump that will deliver 38 CFM at 810 RPM with a max RPM of 900. This pump features head unloaders which can be used with dual control or gas powered engines, this gives you the ability to freewheel the pump while running to lengthen life span of the pump in high-use applications. If this is not needed, just leave the head unloader line unhooked and it will function as a normal compressor.

This pump is most commonly used on compressor tanks of 80 gallons or larger in size unless being used with a gas engine, where in most cases, the tank will be much smaller. It can be used with a 20 HP or larger gas engine or a 7.5-10 horsepower electric motor. To verify your electric motor is large enough, it should be 30 amps or higher at 220 volts and at least 7.5 HP. This pump has a minimum RPM of 710. This pump comes complete as shown in the photos, including intake filters and flywheel. See specifications below for more details.
