Style:QBY3-25APP 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. Application: Suitable for strong acid and alkali, corrosive fluid.

Would not purchase again. I guess you get what you pay for.
Poor fabrication. Had trouble threading fittings into supply and discharge ports.

Very poor quality
Advertised that it will pump waste oil did 1 time and will only spit. Took apart steel balls hard teflon bottom does not seal correctly to suck. I rebuild 2 and 3 inch diaphragm pumps at work very poorly constructed.

leaks around the diaphragm bolts..
It pumps but leaking around the diaphragm bolts. Was going to use it for windshield washer fluid. That's not happening unless the seller replaces this defective unit. I must also say it does look like a quality unit.
