WARNING Failure to follow these instructions could result in serious bodily injury or death. Do not attempt to work on any Tuthill pump installation before completing the steps below. Disconnect the drive so that it cannot be started while work is being performed. Review the Material Safety Data Sheet (MSDS) applicable to the liquid being pumped to determine its characteristics and the precautions necessary to ensure safe handling. Vent all pressure within the pump through the suction or discharge lines. All Tuthill pumps contain residual hydraulic oil from the factory production test....

Packing Adjustment WARNING Packing is designed to leak. Therefore, when pumping hazardous liquids, a mechanical seal is recommended to minimize any potential source of leakage that could result in a hazardous condition. All packings must leak to perform properly. Their purpose is to control leakage—not to prevent it. The slight leakage along the shaft provides proper lubrication to the packing. Pump packings have a lubricant, which acts as a primary sealant for the start-up and breakin phases, during which this lubricant acts to reduce friction. Once the pump is on the line, external...
