Introduction



As you know, Flexible impellers are the most important part in Flexible impeller pumps. We improve the impeller performance by special surface coating, decreasing wear and tear so the impellers can last for long time. We recommended you should change the impeller every year. We can guarantee that you will have great satisfaction with JMP flexible impellers.




Flexible Impeller Materials


Neoprene Neoprene impellers are the standard impeller used in most flexible impeller pumps. It offers a wide range of chemical resistant properties. Temperature range: 45F ~ 180F

Nitrile Nitrile impellers offer compatibility with oil products. It handles a wide range of oils, oil and water emulsions(or bilge), diesel fuel, lower fraction hydrocarbons, kerosene, lubrication and machine oil. Temperature range: 50F ~ 180FNotice : Generally Nitrile impeller's performance is below 10% that of neoprene.

Viton Viton impellers are recommended when pumping hydrocarbons, solvents and severely corrosive chemicals.Temperature range: 60F ~ 180FCaution: Viton

Sanitary Neoprene Sanitary Neoprene impellers are used in the hygienic flexible impeller pumps for applications pumping food, beverage and pharmaceutical products.Temperature range: 22F ~ 120F

Insert materials

Brass : General purpose
Stainless: Special purpose ( for sanitary, chemical etc)
