The AQUAJET pumps have a computer driven controller. So when the pressure goes below the start set point 40-42PSI the pump comes on line and provides what is demanded of it at around 50PSI. This controlled by the computer sending a signal byway of PWM (pulse with modulation) that controls the speed of the motor say 800RPM. When a second outlet (Faucet) is turn on the pressure drops and the computer see's the drop and adjust the speed to compensate for 2nd outlet back to 50PSI, again adjusting the RPM through PWM to achieve that. When the second faucet is turned off the controller see pressure increase and adjust RPM backdown, when the first faucet is shut off the system pressure rises to 63-67 PSI and it shuts the pump off.
Simple explanation-if you have 3 facets in an RV that are rated at 1 gallon per minute flow. When the first is opened the pump comes online and gives 1 GPM of flow at 50PSI, second faucet is turned on pump speeds up to supply 2 GPM at 50psi, third faucet is turned on pump speeds up again to supply 3GPM at 50psi.
