The Mongoose is the smallest frame-mounted manual injection pump in the pipeline service industry today. The patent pending, breech-lock cap makes filling the barrel extremely quick and easy when using packing, sealant and lubricant sticks, liquid flushes and valve cleaners. One ounce of product is dispensed for every 11 strokes of the foot pump which makes it extremely accurate when servicing smaller valves or energizing stem seals. The removable handle adapts to the foot pump bar to allow for hand operation in two positions and also secures the breech-lock handle for easy transport. An optional magnetized wheel assembly makes moving the Mongoose easier when servicing valves in a large yard or facility.
