If using multiple ESPs, which one should be started first?

Starting the Emergency Pump System (ESP) from the bottom is the most effective approach to prevent motor damage and ensure operational efficiency. When multiple ESPs are in play, initiating the pump at the lowest location helps maintain proper water flow and system pressure, reducing the risk of overheating and electrical strain on the motors.

By beginning with the pump located at the lowest point, you help promote a consistent and manageable flow of water, which is critical during damage control operations. This method minimizes the load on the motor and prevents dry running, which can lead to motor burnouts. It strategically utilizes gravity to your advantage, ensuring that lower pumps effectively manage incoming water before additional pumps are activated. This sequential approach not only protects the equipment but also enhances overall efficiency during emergency water removal operations.
