3.
Open the suction valve.
4.
Start the priming system.
5.
Run the priming system until a continuous stream flows through the suction line, then close the valve to
the vent.
6.
The pump is now primed.

Starting The Pump:

Initial Startup:

No specific procedures are required for initial startup unless the pump has been in storage. If the pump has been in
storage, refer to Storage of Pumps found in section 1, of this manual. Start the pump in accordance with Routine
Starting below.

Routine Starting:

A.
After the pump is primed, and with the discharge valve closed and the suction valve open, start the driver
according to the driver manufacturer's instructions.
B.
Open the discharge valve slowly to prevent water hammer.
C. Immediately after the pump has been started, check the following:
1.
Bearing temperature,
2.
Stuffing box lubrication and operation
3.
Pump unit noise level.
4.
Pump unit vibration level.
D. Continue to monitor these values for the first several hours of operation.
E.
After the unit has stabilized and is operating normally, record readings for future use in preventative
maintenance.

Bearing Operating Temperature:

These pumps are designed to operate over a wide ambient temperature. The temperature, when measured on the
outside surface of the bearing housing, should not exceed 190 degrees F. Temperatures in excess of 190 degrees F
may indicate a lack of lubricant, or bearing problems. If the temperature exceeds this limit, the pump should be
stopped and the cause investigated and corrected.

Regulating / Control Procedure:

Pump stations are usually designed to have the pumps started and stopped automatically using a controller. Since
this is a function of station design, the operators should be thoroughly familiar with the systems operating
parameters and in the use of the controller.
A.
Disconnect the electrical power.
1.
Lock out the power to the driver.
Check power source with appropriate electrical test equipment to ensure driver cannot accidentally start
B.
If the pump is to be removed for repair, close the suction and discharge valves.

Emergency Procedures:

Many installations are equipped with emergency shut off switches near the pump location. These locations should be
plainly marked and be readily accessible at all times.
The control panel (if used) may be equipped with an emergency stop button or switch.
