OPERATION

s
WARNING
! DO NOT run pump against a closed discharge.
This may cause hazardous pressure and risk of explosion.
s
CAUTION
! Do not run the pump before priming it. The seal
and impeller could be permanently damaged.
s
CAUTION
! DO NOT run the pump before filling the pump
case with liquid. Doing so may damage the seal.
s
CAUTION
DO NOT run pump dry. Fill pump with water
!
before starting pump. Operating pump dry may cause damage to pump
and will void warranty.
A priming port plug is provided in the top of the casing to fill the pump
with water. Once filled and the priming plug replaced, the pump will
prime. The priming time depends upon the vertical and horizontal distance
between the pump and the water level.
1. Remove priming port plug from pump (Figure 7).
2. Open discharge valves and any hoses on discharge side of pump.
3. Fill pump with water through the priming port on top of pump. Allow
trapped air to escape for a few minutes, then add more water until full.
4. Replace priming port plug and tighten with wrench, using PTFE tape
on pipe threads.
5. Start the pump. A properly primed pump should discharge water
without air at a consistent pressure. If the pump does not produce
water after five minutes, stop the pump, release all pressure, remove
priming port plug, add more water, replace plug, and try again.
Ensure that a foot valve is properly installed on the suction pipe
(Figure 5). If an exceptionally long suction line is used, the water
in the pump casing may become overheated or vapourlocked.
Should this occur, replace the water in the casing with cold water
and continue priming.
s
CAUTION
!
Never operate the pump dry as this may damage the seal.
