Working Principle In the pump two symmetrical working chamber each equipped with a diaphragm, the center link will be integrated into one. Compressed air from the pump inlet into the valve, through the valve body to introduce compressed air into one of the chamber to promote movement of the diaphragm chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison. Feature Efficiency: Motor design delivers optimum air efficiency. Reliability: "Unbalanced" air valve ensures no-stall operation. Environmentally Sound: Bolted construction for leak-free fluid handling. Serviceability: Easy access to ball checks and fluid caps for maintenance and repairs. Air Operated Diaphragm pumps can operate dry and does not fail to work. Diaphragm pumps are intrinsically ex-proof and fire-proof as being operated with air. In addition flow rate can be adjustable by air pressure. High Quality Cast Iron This air-operated double diaphragm pump is made of high quality cast iron, which has good abrasion resistance and heat resistance, durable and tough. Easy to Maintain Bolted construction for leak-free fluid handling, motor design delivers optimum air efficiency. Easy access to ball checks and fluid caps for maintenance and repairs. Wide Application Perfect for use with water. Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil. This powerful and efficient air operated diaphragm pump is perfect for all your needs in every industry.

How do I get a rebuild kit for this pump. As my previous review said, I tried it with oil after it was received. It worked fine. The first time I actually needed it (6 weeks after purchase) it doesn’t work at all. It’s blowing oil out of the exhaust. I purchased it in May, it didn’t work the weekend before July 4th. Again, how do I get a rebuild kit because my return window had expired. Please help!!I have no way to contact CNCest?
