Complete Guide to Grease Pumps: Types, Pressure Ratios & Selection | IsoHiTech

Grease pump guide: how air-powered pumps turn a pressure ratio (a 50:1 pump on 6 bar air reaches roughly 300 bar on the grease side in theory) into delivery pressure, typical operating ranges from 725 psi light-duty to 5,800 psi heavy-duty, and gear, piston or progressive-cavity mechanisms.
