APPLICATIONS Conveying fluid and viscous liquids, such as waste oil, ethanol, gasoline, engine oil, diesel oil, mud, lime slurry, sewage, cement, antifreeze EB solvent-2-butoxyethanol, industrial coating DEF is purified from urea CNC coolant, acetone, gear lubricant, isopropanol. Widely used in petroleum, metallurgy, mining, paint, printing, water treatment, automotive and other industries.
Premium Double Teflon Diaphragms with an Extra Set of Diaphragms Our air-operated double diaphragm pump adopts Teflon diaphragms, durable, corrosion-proof, and long-lasting. Max. Temperature 150 ℉/66 ℃; Max. Pressure 120 psi; Max. Flow Rate：35 GPM; Max Head Lift：226.4 ft/69 m.
MAIN FEATURES no lubrication, medium and pump parts completely separated, delivery toxic, medium will not corrode leakage, low energy consumption, small gas consumption, Modular design, low maintenance costs, long life, good heat resistance.
ADVANTAGES no spark, no liquid suction will not damage the pump, flow and head can be adjusted by valve switch size, suction can be adjusted by pressure, can be immersed in the medium work, high viscosity and low viscosity liquids can be extracted.
HOW IT WORKS pneumatic diaphragm pump to Compressed air power, diaphragm installed in the pump's two symmetrical chambers, the central connecting rod will be integrated as a whole together. The Compressed air enters the valve through the inlet of the pump and is directed through the valve body into one chamber to facilitate movement of the diaphragm while Compressed air gas from the other chamber.
This Pneumatic double diaphragm pump is pretty well made. It does the job well and I like the fact that they include a video of it actually being assembled. There are many benefits for a pump like this. I like these types especially because you can get the pump close to the liquid source but have the pneumatic compressor far enough away that you can’t hear it. Or you can put it in a sound dampening box. Either way you can make it very quiet where the pumping is happening. It also can be used for many different liquid chemicals. So far, I think this one is pretty impressive.
