Rolair PMP22K30CH Two Stage Pump With Flywheel

The PMP22K30CH is Rolair's two-stage belt-drive air compressor pump with a flywheel, built with cast-iron cylinders and an aluminum head and crankcase to help dissipate heat quickly. It uses splash lubrication with bearing inserts on the connecting rods, Swedish Lamellar Reed Valves, an oil sight gauge and a filter as standard equipment, and includes a 15.16-inch aluminum flywheel for smooth operation at low RPM. The unit runs at 800–1200 RPM and is rated 5–7.5 HP, delivering about 16.01–23.63 CFM at 175 psi (20.52–30.78 CFM displaced), supported by a 47 oz oil capacity, 4.13" bore on the low-pressure side, 2.05" bore on the high-pressure side, and a 3.31" stroke across two cylinders and two V-belts. The assembly weighs around 83.8 lb and is listed as PMP22K30CH, a two-stage pump with flywheel in Rolair's catalog.
