OVERVIEW: Original pumps were suffering severe corrosion and cavitation
With our RB 300 series coating system, these pumps can now expect long term protection with minimal maintenance.
INDUSTRY
ENVIRONMENT
Ambient Sea Water
SUBSTRATE
Admiralty bronze 200/200
CHALLENGE
Original pumps were suffering severe corrosion and cavitation
SOLUTION
We recommended the use of RB 300 series @ 1200μm nominal thickness and top coat with 2 coats of RP 500 @ 300μm
SCOPE
Pre machine critical dimensions
Abrasive blast to ISO 8501-1 cleanliness standard with a minimum 75μm profile
Mask and protect all area not to be coated
Application of 2 coats of RB 300 series
Application of RP 500 in two coats to improve fluid efficiency
Post machine to allow re-assembly
Balance impeller as required
PRODUCTS
Chem-tect™ RB 300 – Glassflake filled vinyl ester
Ceram-chem™ RP 500 – Ceramic filled epoxy designed to improve lumber flow
OUTCOME
Some engineering changes were made to the strainer system prior to the installation of these 3 pumps. Coupled with our coating system, these pumps can now expect long term protection – with minimal maintenance. Tube sheets, pipe-work and many other components have been protected using similar methods both on site and within our fully equipped workshop located in Wollongong
