Jabsco 4732-0000 - Vacuum Switch

Jabsco 4732-0000 - Vacuum Switch

The Jabsco 4732-0000 Vacuum Switch is designed to protect Jabsco flexible impeller bilge pumps from dry running, ensuring the longevity and reliable performance of your pump system. This vacuum switch detects the loss of inlet vacuum when the bilge is dry and air enters the pump, automatically cutting off the system to prevent damage. It is ideal for installation with Jabsco electric-clutch pumps or can be fitted into a suitable T-piece in the pump inlet line for added versatility. The switch has a ¼” BSP internal thread connection for easy integration. A minimum 1.2m suction lift is required for installation, and a manual start is required, with automatic cut-out for safety. For remote start capabilities, a 15 amp push button switch (normally off) can be added next to the master switch for convenient operation.
