3-Inch Polypropylene Air Operated Diaphragm Pump - 270 GPM Flow Rate, 120 PSI Max Pressure for Chemical and Dirty Water Applications
This 3-inch polypropylene diaphragm pump is engineered for handling dirty water and chemical fluids with flange connections. The air-operated design ensures reliable performance in demanding industrial applications.
The pump features two symmetrical chambers with diaphragms connected by a central stem. Compressed air enters through the inlet valve, pushing the diaphragm and creating reciprocating movement that continuously transfers fluid from inlet to outlet.
- Flow automatically adjusts based on outlet resistance, ideal for high-viscosity fluids
- Explosion-proof operation with no spark generation or overheating
- Compact, portable design requiring no foundation for installation
- Complete fluid isolation for handling hazardous and corrosive materials
- Low shear force for transporting unstable chemical fluids
