●Power saving 23-55%.

●It can reliably realize soft-start and alternate operation for multiple pump sets, greatly prolonging the equipment's  service life.

●Various automatic protection functions such as undervoltage, overvoltage, overcurrent, overload, short circuit, overheating, stall, etc.

●Adopt digital PID adjustment, high precision constant pressure and small fluctuation of water pressure.

●It can meet requirements of various working condition such as constant pressure variable flow and variable pressure variable flow.

The constant pressure water supply system is a fully automatic controlled constant pressure water supply equipment. When the water consumption does not exceed the water output of a single pump, the water supply is maintained by a single pump. When the water consumption exceeds the water output of a single pump, the pressure sensor is used. When the pressure of the fluid in the sensing tube drops, after analysis and calculation, the microcomputer controller outputs a signal to the frequency converter according to the calculation result, and the frequency converter controls the operation of the frequency conversion main pump and adjusts the number of pumps according to the water consumption, thereby greatly saving electricity and water.
