What happens to the speed of the VP-1000 pump when the second nozzle is activated?

When the second nozzle is activated on a VP-1000 pump, the speed of the pump increases to accommodate the higher demand for vapor recovery. This increase in speed is necessary to ensure that the system can effectively handle the additional flow being generated by the activation of the second nozzle.

By ramping up its speed, the pump can maintain an efficient vapor recovery operation, preventing vapor loss and ensuring that the system continues to function effectively under increased load conditions. This dynamic response is crucial in vapor recovery systems to keep emissions within regulatory limits and protect the environment.

In contrast, if the pump were to decrease, stabilize, or shut down, it would not meet the necessary operational requirements for effective vapor management, leading to potential failures in vapor recovery and increased environmental risks.
