SKU: OP004 Categories: , ,


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.

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.

Thunder pumps can be serviced in the tank or drum using just a standard wrench.

Thunder pumps are constructed with 50% fewer parts than the majority of comparable pumps. Fewer parts means less problems.

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.

    I’m amazed, I have to admit. Rarely do I come across a
    blog that’s both equally educative and engaging, and without a doubt, you
    have hit the nail on the head. The problem is an issue
    that not enough folks are speaking intelligently about.
    I am very happy I came across this during my hunt for something relating to this.

    This might be a problem with my browser because I’ve had this happen previously.
