The GoatThroat precision hand pump is constructed of non-reactive polypropylene with all wetted parts made of food-grade materials. Pump fits any container from 5 to 55 gallons. A few strokes of the piston pressurizes the container. The patented internal pressure relief opens at 15 psi, making the pump safe to use with UN certified Dangerous Goods Containers. A drip-proof faucet dispenses small amounts or gives steady flow and helps prevent potential hazardous leaks. The air-pressure dispensing system allows containers to be completely drained while remaining in an upright position.
