START UP
Before pushing “start” button, check the following:
1. Are vacuum and pressure gauges (liquid filled) mounted on or near the pump? Gauges are
the quickest and most accurate way of finding out what is happening in the pump.
2. Is the pump is correctly aligned with the drive equipment?
3. Make sure there is no pipe strain on the pump ports.
4. Rotate the pump shaft by hand to be sure it turns freely.
5. Before connecting to the motor, jog it to be sure it is running in the correct direction. Refer
to “General” on page 3.
6. Is the pressure relief valve installed properly?
7. Make sure the suction piping is properly connected and sealed, and valves are open.
8. Make sure the discharge piping is properly connected and sealed, valves are open, and there is
a place for the liquid to go.
9. Make sure all guards are in place.
10. The above checklist is a general guideline to be used prior to starting the pump. Since Viking
Pump cannot foresee every application for our product and possible system design, the final
responsibility is with the user. The pump must be utilized within the catalog specifications and
the pump system must be designed to provide safe working conditions.
The “start” button may now be pushed.
The pump should begin to deliver liquid within 15 seconds! If not, push the stop button. Do not
run the pump without liquid flow longer than 30 seconds or the pump may be ruined.
Review Startup steps 1 through 10. Consider what the suction and discharge gauges may
indicate. If everything appears in order, re-prime pump. Refer to Mounting page 3, item 6.
Push the “start” button. If nothing is flowing within 30 seconds, stop the pump. The pump is not
a compressor, it will not build up much air pressure. It may be necessary to vent discharge line
until liquid begins to flow. Use safe venting procedures especially when handling hazardous
liquids
If pump still does not deliver, consider one or more of the following:
1. The suction line has air leaks.
2. The end of the suction pipe is not submerged deeply enough in the liquid.
3. The suction lift is too great or the suction piping is too small.
4. Liquid is vaporizing in the suction line before it gets to the pump.
Danger !
Before starting pump, be sure all drive equipment guards are in place.
Failure to properly mount guards may result in serious injury or death.
