SECTION 3 OPERATION
3.1 START-UP PROCEDURES AND CHECKS
Check that the pump is secured to its support.
If oil was previously removed for any reason, make sure pump drive has the correct volume (650 ml) of oil as below:
Recommendation oil:
Note: Equivalent oil of other brand is allowed.
Caution: Pump is required to stop running providing the surround temperature is below -10
℃
.
Make sure all isolation valves installed on the suction and discharge lines are open. If the discharge line is
equipped with an injection nozzle or a back-pressure valve, open the priming valve for discharge (if there is no
priming valve, disconnect the discharge pipe). This allows for verication that liquid is present in the liquid end
when the pump is installed in ooded suction condition. If the pump is installed in a suction lift condition, this
allows for priming of the pump during start-up.
Make sure that pump is set at 0% capacity.
3.2 CHECKING THE ELECTRICAL CONNECTION OF THE MOTOR
Start up the pump to check the motor's direction of rotation. It must comply with that indicated by the arrow
marked on the motor mount ange of housing (counter clockwise as viewed from the top of the motor). If the
rotation is incorrect, refer to Section 2.8 Electrical Connections.
3.3 START-UP
Once all the checks and procedures described above have been carried out, start the pump.
Conduct a visual and audio check of the pump (in particular, listen for the presence of any "suspicious"
noises).
Make sure that the stroke adjustment knob is unlocked.
Gradually increase the capacity until liquid can be seen owing from the priming valve. If no priming valve is in
place, when the liquid end is primed, the discharge check valves can be heard to be operating (should hear a
clicking noise caused by movement of check valve balls). When liquid end is primed, stop the pump and close
the priming valve.
