Another word of advice, be sure that the condenser water temperature is allowed to drop as the flow/load decreases.
We had to replace the thrust bearing on a machine less that two years old. I feel a lot of the surging was caused by the control system resetting the chilled water flow from outside air temperature, with no reguard to the rate of change (possibly too sensitve to ambient change would be more accurate), that and a cooling tower system set to provide 80 degree condenser water come hell or high water.
I'm not a real engineer, but I play one on T.V.
