Priming a pump involves filling the pump and suction line with the fluid that needs to be pumped to create a vacuum. This allows the pump to start pulling and transferring the fluid. General steps to prime a pump are as follows:
Fill the pump casing with the fluid to be pumped until it reaches the centerline of the impeller.
Close all of the pump suction and discharge valves.
Open the vent valve on the discharge line.
Start the pump motor and let it run for a few seconds to release any air in the pump casing and suction line.
Slowly open the suction valve until the fluid enters.
Close the vent valve once the fluid is flowing smoothly.
Open the discharge valve slowly until the desired flow rate is achieved.
Exact steps for priming a pump will vary depending on the specific pump design and application. Consult the manufacturer's instructions or a ProSeal pump specialist for specific instructions on how to prime your pump.
