1-A) INCOMING CONDITION & DISMANTLING

The process began with the dismantling of parts followed by a dimension and run out check. A bore check is done on the impeller and a dimension check is done on the wear ring. Masking and blasting is then carried out, as well as coating.

2-A). MASKING & BLASTING

To complete the task, a combination of techniques such as blasting, welding and machining were carried out by our team on the top sheaves.

2-B). PRIMER COATING (ONLY FOR EXTERNAL PAINTING

To complete the task, a combination of techniques such as blasting, welding and machining were carried out by our team on the top sheaves.

2-C). EXTERNAL COATING RAL6019 PASTEL GREEN AS PER OEM SPECIFICATION

2-D). INTERNAL COATING USING CERAMIC POLYMER CN200

Finally, the reassembly is done with new consumables, ending with a pressure test.

PRESSURE TESTING MAX SUCTION PRESSURE = 5 BAR REQUIRED TESTING PRESSURE = 5 BAR X 1.5 = 7.5 BAR
