1. NEOPRENE is the standard impeller material used in most flexible impeller pumps. It offers a wide range of chemical resistant properties.
Temperature range: 45°F to 180°F
2. NITRILE impellers offer compatibility with oil products. It handles a wide range of oils, oil and water emulsions, diesel fuel, lower fraction hydrocarbons, kerosene, lubricating and machine cutting oil.
Temperature range: 50°F to 180°F
Lower temperatures affect priming ability and performance characteristics. Generally, nitrile performance is 10% below that of neoprene.
3. VITON impellers are recommended when pumping hydrocarbons, solvents and severely corrosive chemicals.
Temperature range: 60°F to 180°F
Viton is not recommended for low temperature or high pressure applications.
