- It was necessary to provide a basis for the design of modifications to the 190-K pumping units to achieve increased process water flow rates. The prototype pumping unit was inspected for cavitation damage after 3 months operation. The low lift pump impeller showed no cavitation damage, while the high lift pump impeller showed excessive damage. The lower max flow capacity and slightly increased power requirements of the third prototype impeller should not preclude its use if its cavitation performance proves satisfactory. Required combined five and six pump flow rates would be achieved with proper sizing of impeller diameter. Adequate margin of safety would exist between design operating points (five and six pump operating points) and max capacity. Under four pump operating conditions, the flow would be reduced 1% below that of the first impeller design, and the bulk outlet temperature surge would be increased one degree following instantaneous reduction to four pump operation.
