Product Description
Product Overview
This 3-inch plastic pneumatic diaphragm pump with flange connection is engineered for demanding chemical industry applications. Utilizing compressed air as its power source, it safely handles corrosive, viscous, and volatile fluids with exceptional reliability.
Working Principle
The pump features two symmetrical chambers equipped with diaphragms connected by a center coupling stem. Compressed air enters through the inlet valve, driving diaphragm movement in one chamber while expelling gases from the other. At the end of each stroke, the air distribution system automatically redirects compressed air to the opposite chamber, creating continuous synchronized reciprocating motion that enables consistent fluid transfer.
Key Advantages
- Flow automatically adjusts based on outlet resistance, making it ideal for high-viscosity fluids
- Intrinsically safe operation - no sparks or overheating in flammable environments
- Compact, portable design requiring no foundation - perfect for mobile applications
- Complete fluid isolation for handling hazardous and corrosive materials
- Low shear force minimizes physical impact on sensitive chemical fluids
