Product Details

Pump Mount VFD (Variable Frequency Drive) is an intelligent motor controller designed specifically for constant pressure water systems.

It:

• Converts single-phase 230V supply → three-phase 230V output
• Drives 3-phase pump motors
• Maintains constant pressure automatically using PID control

👉 In booster systems, it adjusts pump speed based on water demand, avoiding full-speed operation and saving energy.

🔷 Key Features (Pressure Booster Specific)

• ✔️ Constant pressure control in pipe line
• ✔️ Automatic speed variation based on demand
• ✔️ Soft start & soft stop (no pipeline shock)
• ✔️ Built-in sleep mode (stops when no demand)
• ✔️ Auto restart after power failure
• ✔️ Dry run & low water level protection
• ✔️ Digital display (pressure, frequency, current)
• ✔️ Energy-saving intelligent algorithm

🔷 Working Principle (Booster Mode)

1. Pressure sensor sends signal (4–20mA)
2. VFD compares actual pressure vs set pressure
3. Adjusts motor speed accordingly:
   • Low demand → low speed
   • High demand → high speed
4. Maintains constant pressure in pipeline
