Priming Systems
-
The priming system of a centrifugal pump is an independent component part of the total pumping system arrangement. Besides the size of the pump, it is also critical to the selection of the suitable system whether the pump mainly has to be evacuated before starting (e.g., pumps working from sea water tank) or whether during and at the end of the pump operation air/gas has to be discharged from the system (e.g., bilge, ballst or cargo pumps)
Examples from our Scope of Supply
-
Centrifugal pumps that mainly have to be evacuated before starting may be equipped with attached pressure controlled priming systems.
Example: pumps working from the sea water tank.
-
Pumping systems that have to be primed also during operation may be equipped depending on the volume of air intake with pressure control priming systems. These are installed on the suction line in front of the pump.
Example: smaller bilge and ballast pumps.
-
Pumping systems where larger amounts of gas volume have to be evacuated during pump operation requires level controlled priming systems.
These have to be installed in front of the centrifugal pump too.
Example: larger bilge and ballast pumps
-
Pumping systems where large amounts of gas volumes have to be evacuated during and especially at the end of pump operation are to be equipped with level controlled priming systems which enable efficient separation of gas from the discharge liquid
Example: larger bilge and ballast pumps or cargo pumps with stripping function.
-
Central vacuum system enables the connection of several centrifugal pumps. Each linked centrifugal pump is equipped with a pressure level-controlled gas discharge valve which will be selected based on the above-mentioned requirements
