Marine FAQ

Do you make rubber impellers for outboard motors?

No. Matson manufactures cast and CNC machined metal impellers for marine pumps. We do not produce rubber outboard impellers.

What materials are used for marine pump impellers?

Nickel-aluminum bronze, bronze, duplex and super duplex stainless steel are the most common for seawater and marine service.

Can you supply impellers for ship cooling and ballast pumps?

Yes. Custom marine impellers for cooling, ballast, bilge and seawater pumps are routinely produced.

Do you support marine certification documentation?

Material certificates and dimensional reports are standard. Class society approval depends on the project — please share the requirement.
