I'm not familiar with VaporWorx PWM pump controllers, but they generally vary voltage to the pump. Caution needs to be used when selecting a pump, and you need to understand the pump's operating voltage range.

You may need to adjust the pump voltage range within the VaporWorx controller to match the pump in use. If it is not adjustable, it needs to be within spec that VaporWorx recommends.

If voltage drops below X, and is outside of the low range of the pump, the pump just stops pumping. The sensor/transducer signals the controller psi has dropped out of range, and immediately increases voltage. If the voltage range is out of spec for the pump, it can cause an on-off-on-off rollercoaster.

Sensor/transducer also needs to be able to respond within a spec for the controller, and not have an error range outside of recommended for the controller.
