Sorry for the delay. After two days and no answer i am lost. I put gauges on discharge and suction side of both pumps. Both pumps were the same, I checked the gauges down the line still the same. I added water to the tower til i could not get any more in no change. I am strating to think this...
I am going down Wed. We had to rebuild the pump with bearings sleeves (were worn) and new packing.Impeller rings and case rings were in toerlance so nothing was done with them. I belive this has always been there but is know getting worse. I am going to look in to a bunch of different thing...
Thanks i have check the stainer they are clear. I am going down later this week with gauges. I wll check all that out and the water level in the tower and let every body know what i find Thanks.
I have a split case pump on a cooling tower. That is vibrating and noisy. While checking this pump out after a total rebuild I noticed that I have a negative suction on this pump. If I open the value on the suction side were the gauge would be and let air in to the pump the noise and vibration...
