Rolair PMP12K18CH Industrial Air Pump With Flywheel And Aftercooler

Rolair PMP12K18CH is a belt-drive, two‑cylinder, single‑stage air pump with an 11.02‑inch aluminum flywheel and an integrated aftercooler, designed as the pump head for Rolair’s belt‑drive single‑stage compressors. It is rated 2–3 HP and displaces 11–16.5 CFM, delivering 7.48–11.2 CFM at 100 psi, with splash lubrication and a 34 oz. oil capacity. The pump uses a 2.75‑inch bore and a 1.97‑inch stroke, driven by a single V‑belt (1‑A), and has a shipping weight of 37.5 lb. Standard equipment includes a crankcase breather, oil sight glass, and a filter, reflecting its configuration as a 1‑stage pump with flywheel and aftercooler for smoother operation and cooler air discharge.
