This is an Ingersoll Rand Type 30 model 2000 bare compressor pump. The 2000 is a two-stage (three cylinder) 100% cast iron piston pump. The 2000 bare pump was most commonly used with the Ingersoll Rand 20hp 2000E20 and 2000E25. This was most commonly paired with a 20hp compressor motor but there were several that were also paired with a 25hp motor. This pump can be used on models that have a pilot valve that controls the compressor by running in constant run more or start/stop mode. This pump does include the low oil level shutdown switch.
If instead your compressor pump does not have constant run head unloaders or strictly operates in start/stop mode via the pressure switch, you will want to order the 2545V bare pump. Please contact us if you would like confirmation on which pump is correct for your compressor.
A centrifugal unloader is included with the pump. The centrifugal unloader automatically bleeds the air from intercoolers and cylinders, preventing the compressor from starting against full load. This protects the motor from premature wear.
