Improved pump hydraulic selection reduces cavitation risk

Follow these guidelines to improve reliability

Budris, R., Consulting Engineer

I n process plants, the cost of unscheduled maintenance is typically the most significant cost of pump ownership. In view of this, pump reliability improvements are actively pursued by reliability-focused users, with the primary focus normally aimed at the mechanical aspects. Not to be overlooked is the fact that further maintenance cost improvements can be achieved through proper pump hydraulic selection. More specifically, better attention should be paid to key hydraulic factors ? such as those associated with pump hydraulic forces (dynamic and static) ? suction recirculation, cavitation and wear within the pump. Improvements in ?mean-time-between-repair? (MTBR) will be limi
