ABSTRACT
If we accept Renner's opening statement as valid, it logically follows that the family home, car, lawn mower, swimming pool, HVAC system, and other home appliances all need routine maintenance. As with most of the possessions we own, every centrifugal pump also requires a certain amount of routine maintenance. Whether it is a daily inspection and adjustment of the packing gland or a yearly inspection and adjustment of the shaft and coupling alignment, a centrifugal pump requires some maintenance to provide reliable service throughout its normal operational life. 26Renner, D., Hands-on Water/Wastewater Equipment Maintenance.
