Title:
PROTECTIVE COATINGS FOR PUMPS
Document Type and Number:
WIPO Patent Application WO2006119223
Kind Code:
A8
Abstract:
The impellor, housing, flow channels, inlet and outlet flow passages of a pump used to pump a highly abrasive liquid at high volume. The flow surfaces are prepared, a primer is applied, and polyurea is applied on top of the primer to provide a protective coating rivaling extremely hard surfaces. The coating thus applied has at least the durability of expensive-to-apply hard coatings such as tungsten carbide, and siloxirane ceramic and ceramic metal filled epoxies. In addition, it minimizes the occurrence of cavitation within the pump housing, flow channels and passages.
