PRODUCT DESCRIPTION

ARO lubrication pumps handle motor and gear oils, transmission fluid, and standard and industrial greases

50:1 ratio Aro "Thunder" grease pump with 2" air motor for 35-pound. Includes bung adapter. Air inlet 1/4"(F) and fluid outlet 3/8"(F). Pump rated at 6 pounds per minute free flow and 2 pounds per minute working flow.

Includes bung adapter. Air inlet 1/4"(F) and fluid outlet 3/8"(F). Pump rated at 6 pounds per minute free flow and 2 pounds per minute working flow.

Reliable Design - Thunder pumps feature a patented, ice-free air motor contained in a rugged housing that is designed to withstand the harshest working environments.

Thunder grease pumps have 5/16" inlet holes in the sides of the bottom of the pick up tube. This helps eliminate problems caused by sucking plastic grease drum liners into the pump's lower section

The air valves and the piston are pre-lubricated. Thunder pumps do not require an air line lubricator

Thunder's patented valve design uses no trip rods, push pins, or springs. Instead of one mechanical pilot valve in the air motor, Thunder has two independent 3-way spool valves which work together to change the direction of the pump piston
