Teflon® coating and Electroless-Nickel plating is available for
Yamada pumps for two primary reasons:
Pump installation in a chemically aggressive location where
material or fumes not compatible with Aluminum may contact
the air motor.
If properly selected, the coating or plating will defend the major
Aluminum air valve components from the fluid being pumped.
For internal and external protection, the four major air motor
components are independently coated or plated then assembled.
