Notes on the Standby Pump :
- The Standby Pump substitutes for either the process pump or the tower/evaporator pump on occasions when service and/or maintenance is required on these pumps.
- The standby pump is connected to the process and tower/evaporator pumps via the standby pump manifold. A series of suction and discharge valves control the flow of these pumps.
Use this chart to correctly open/close the suction and discharge valves for standby pump operation.
