ZHG-9603 Series constant pressure pump controller is specialized for constant pressure water supply pump variable frequency controller. The constant pressure water supply controller can make water supply systems run stable and reliable. Achieve a true automatic cycle pump together with variable frequency operation. Use it to ensure optimal running efficiency of each water pump and stable operation of equipment and smooth start. Eliminates high current shocks and lowers the pump’s average speed, extending pump life and eliminating water hammer during start-up and shutdown.
1. Include 3 units main pumps & one small pump, multiple control modes,
2. Timing change pump function, control all kinds of pumps working time. Improve average life of pumps,
3. Up to 8 period pressure control, pre-select pressure control timer ON/OFF function,
4. Sleep function and auxiliary small pump function, save energy and reduce consumption , extend machine’s life,
5. Positive and negative feedback function , use for water supply and maintain water levels,
6. Over-pressure, low water level, sensor disconnection, inverter failure and  alarm control functions,
7. Feedback can connect with passive remote pressure gauge, active voltage and current transmitter.
