ADDITIONAL INFORMATION:
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. ARO is so confident in this design that it is backed by a 5-year warranty.
LUBE-FREE AIR MOTOR
The air valves and the piston are pre-lubricated. Thunder pumps do not require an air line lubricator.
NO MECHANICAL ASSIST
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.
IN-LINE SERVICE
Thunder pumps can be serviced in the tank or drum using just a standard wrench.
FEWER PARTS
Thunder pumps are constructed with 50% fewer parts than the majority of comparable pumps. Fewer parts means less problems.
COST-EFFECTIVE DESIGN
Most competitive pumps are too costly to repair after their warranty expires. Thunder's revolutionary design, inexpensive rebuild kits, and field serviceability all add up to a pump that has the lowest cost of ownership in the lubrication equipment market.
