Refer to the manual ac companying the engine or power source before attempting to begin oper ation. damage the pump or endanger person nel as a result of pump failure. Because pump installations are seldom identical, this manual cannot possibly provide detailed instructions and pre cautions for each specific application.
OM-06553 heated pump. Vapor pressure within the pump can cause parts being disen gaged to be ejected with great force. Al low the pump to cool completely before servicing. This pump may be used to handle mate rials which could cause illness through direct exposure or emitted fumes. Wear adequate protective clothing when working on the pump or piping. Do not operate the pump without guards in place over the rotating parts.
PA SERIES OM-06553 INSTALLATION - SECTION B Review all SAFETY information in Section A. Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and ar range the pump and piping. Most of the information pertains to a standard static lift application where the pump is positioned above the free level of liquid to be pumped. configuration, and priming must be tailored to the specific application.
OM-06553 c. Carefully read all tags, decals, and markings on the pump assembly, and perform all duties indicated. Note that the pump shaft rotates in the required direction. Only operate this pump in the direction in dicated by the arrow on the pump body and on the accompanying decal. Other wise, the impeller could become loosened from the shaft and seriously damage the pump. d. Check levels and lubricate as necessary.
PA SERIES the brake and blocking the wheels before attempt ing to operate the pump. OM-06553 lines are used, they should have adequate support to secure them when filled with liquid and under pressure. Gauges If the pump has been mounted on a mov able base, do not attempt to operate the pump unless the unit is level. Be sure the leveling stands are positioned on a solid surface, and the wheels are chocked.
OM-06553 Sealing Since even a slight leak will affect priming, head, and capacity, especially when operating with a high suction lift, all connections in the suction line should be sealed with pipe dope to ensure an air tight seal. Follow the sealant manufacturer's rec ommendations when selecting and applying the pipe dope. The pipe dope should be compatible with the liquid being pumped.
