both high active pumps ITC:MP1 and MP2 are refurbished by RH group Maico and Peter. Pumps have been installed back to system with new inlet/outlet flange gaskets. high active water surging tank is refilled with water and pumps were primed. I asked operator to switch on pumps separately. Both pumps work fine. They are quiet and pumps discharging pressure is a little bit better comparing to before refurbishment. Nitrogen gas is injecting into system. O2 level is decreasing and R is going up.

2024-04-09: Joel.S checked pumps phase current draw: MP1 16.8 to 17.1A on each phase. MP2 17.0 to 17.2 A on each phase. They are normal. Pump body temperature are below 45C which is fine.
