Subject: HALCW ITC:MP1/MP2 pump and motor temerature measurements 

HALCW ITC:MP1/MP2 pump and motor temperature measurements result:

MP1: pump discharging  port: 78F,  motor rear bearing house:72F  , Motor housing 140F(60C). 6F difference between them is less than 15F manufacturer clarified up limit in instruction manual. 

MP2: pump discharging port:78F,  motor  rear bearing house:72F, Motor housing 122F(50C).

MP1 is better than MP2 on motor status. It could be seen on phase current measurements as well.

Other notes on pump performance:    total flow rate 60GPM , discharging gauge pressure  99 to 100 psi on both pumps with one station all of TM water circuits bypassed + other station  two of TM water circuits bypassed + both stations 2A beam related water circuits  on(2X5).
