RB 300 – Sea Water Volute

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
