Initial Prime
The pump must be primed before it can function within the system. This will require an initial start of
the pump.
Flooded Suction System
1. Close Skid Discharge Valve and Column Isolation Valve
2. Open Air Bleed Valve (turn opening knob counterclockwise, see Figure 9)
3. Open all valve(s) on the suction side – Skid Suction Connection Valve and any valve(s) in your
suction line
4. Connect pump/motor to power source (pump/motor off)
5. Start pump using manufacturer’s recommendations for initial operation settings
6. Observe flow through Air Bleed Bypass. When solid stream (no air bubbles) is observed,
pump is primed.
7. Shut off pump.
8. Close Air Bleed Valve (turn opening knob clockwise)
Note:
Pulsafeeder Pulsatron metering pumps, most
commonly used on Pulsafeeder Pre-engineered
Skid Systems, are self-priming.
If you are not using a Pulsatron pump, check the
specifications for your pump to ensure priming
capability or provision for priming.
When starting an empty pump, use of the air
bleed valve is recommended. In any case,
provision must be made to evacuate air from the
pump discharge port during priming.
!
CAUTION
Thoroughly review the installation, operation and maintenance manual for your pump
prior to starting. Follow pump startup instructions. Failure to do so may result in
damage to equipment or serious injury.
