3.9 Priming the Pump
Completely prime the pump by removing the vent plug (212).
Using a funnel, fill the pump body with water until it overflows and replace plug.
Alternatively for installations with positive suction heads, close the discharge valve and remove
the vent plug.
Open the suction valve until liquid flows out of the vent plug opening and then replace the vent
plug securely and open discharge valve.
3.10 It is recommended that a bleed valve be installed in discharge line or in a line from the vent
port to the reservoir. This will allow the pressure in the pump to be relieved for service.
3.11 Pipe, valves and fittings must have a pressure rating equal to or greater than the maximum
system pressure.
3.12 A bypass or pressure relief valve should be installed in the discharge line if there is any possibility
the pump may operate against a closed valve in the discharge line.
Minimum flow is required for proper cooling and lubrication of the pump without which, damage
and premature failure will occur.
