Materials: AL alloy, cast iron, stainless steel.Product DescriptionAir driven diaphragm pump(QBY)This series of diaphragm pumps are the latest model athome. they are functioned to take out and suck in various corrosive liquid containing granules, viscous, volatile, inflammable, explosive or poisous liquid, porcelain slurry, mashed fruit, flue, the reclamation of residual oil in tanker, temporary reversion of tanker, etc. The performance parameters of this series pump are close to shat of German WILLDEN Pumps and American MARIO-W Pumps. The components in contact with flow are made of stainless steel, aluminium alloy, cast iron and engineering plastics, while diaphragm coulde be NBR, viton, neoprene and PTFE(F4)Characteristic1. No Leakage2. Pump body material: Cast Iron, Aluminum Alloy, Stainless steel, Engineering Plastic, etc.3. Diaphragm material: NBR, viton, neoprene and PTFE(F4), etc.4. QBY pump has two diaphragms, the compressed air come to the pump body to drive the pump in the constant action of sucking and releasing, so it can pump the liquids easily by this principle. Also it is very safe in dangerous environment since it has no electric motor.Performance parametersMax solids can pass: 10mm.
