Is a variable frequency system water pump better than a pressure tank operation? VFD can control the water pump motor and the water speed base on the water usage. With the ability to control the speed of the pump, the water pressure can be increased and decreased in the same flow system and the same pump circle.
Pre-charge pressure refers to the amount of gas (air is used in tanks) in bar/psi that is pumped into a tank prior to installation – usually at the factory. The pre-charge is the “spring” that helps to create water pressure.
