VACUUM PRIMING SYSTEM FOR CLOSE-COUPLED PUMPS
Systems and methods described herein provide a vacuum priming system for close-coupled pumps. The vacuum priming system is mounted separately from a centrifugal pump and powered by an electric motor. An auxiliary vacuum pump pulls prime (e.g., water or another liquid) through a solenoid valve that is in turn connected to a connecting tube. At one end of the connecting tube is a screen and prime sensor. The screen filters particulates to protect the vacuum pump, and the prime sensor may detect when the centrifugal pump is primed. The vacuum priming system includes a self-contained control panel with an auto operation mode to only pull power during priming, reducing power consumption over the lifetime of the pump system and improving efficiency.
SMART VACUUM PRIMING SYSTEM
Systems and methods described herein provide a smart vacuum priming system for centrifugal pumps. The vacuum priming system includes a vacuum pump, a suction assembly, an electromagnetic clutch assembly, and a pressure sensor. The suction assembly provides fluid communication between the vacuum pump and a float box of the centrifugal pump. The electromagnetic clutch assembly selectively engages the vacuum pump, such that a drive shaft of the centrifugal pump also powers the vacuum pump when the clutch is on. The pressure sensor indicates when the centrifugal pump is in a primed state based on a discharge pressure of the centrifugal pump. When the pressure sensor indicates the main pump is in the primed state, the electromagnetic clutch decouples the vacuum pump from the drive shaft. When the pressure sensor indicates the main pump is not in the primed state, the electromagnetic clutch couples the vacuum pump to the drive shaft.
