This JSJ Professional High-Pressure Grease Pump is a heavy-duty pneumatic grease dispensing unit designed for efficient lubrication of industrial machinery, vehicles, construction equipment, bearings, and other mechanical components. It operates with an air inlet pressure of 0.6–0.8 MPa and delivers grease at an outlet pressure of approximately 30–40 MPa, providing high-pressure lubrication for demanding applications. Its robust metal construction, wheeled base, pressure-control assembly, and flexible high-pressure hose make it practical for workshop and industrial maintenance operations.
