An impeller that stands up to applications with chemical exposure.

Nitrile impellers are able to tolerate chemical exposure without breaking down. Ideal for fuel and oil transfer pumps, these impellers are also an excellent choice for boats run in contaminated waters. Sierra makes switching your Volvo Penta engine to a nitrile impeller a little easier by packaging the impeller with a gasket and O-ring together. Each impeller is engineered to meet or exceed Volvo specifications to ensure users of the proper fit and function.
