Supplied with a bung adapter and a 2" (5.1 cm) pump tube, this air-operated stub pump provides a 3:1 pressure ratio for lubricant dispensing systems. It utilizes a double-acting design to achieve a maximum free flow capacity of 11.8 gal (44.7 L) per minute while supporting simultaneous operation at multiple dispensing points. The 3.55" (9 cm) air motor operates between 40 and 140 PSI to move all lubricant types, including those with higher viscosity.
