Variable Frequency Pump – Intelligent Speed Regulation, Constant Pressure Energy Saving

Variable frequency pump is an intelligent water pump system that adjusts motor speed via a frequency inverter to automatically control flow and pressure. It dynamically adjusts its operation based on water demand to achieve constant pressure water supply, reduce energy consumption and minimize equipment wear. Featuring soft start and intelligent protection functions, it is widely used in domestic water circulation, pressurized constant pressure water supply, boiler feed water, and industrial water circulation systems, serving as a core component of modern, energy-efficient water supply solutions.
