VARIABLE FREQUENCY PUMP SERIES
ALFAGRAND variable frequency pumps combine permanent magnet synchronous motors with intelligent VFD controllers. Achieve constant water pressure with up to 40% energy savings compared to traditional fixed-speed pumps.
What is a Variable Frequency Pump?
A variable frequency pump uses a permanent magnet synchronous motor (PMSM) controlled by a variable frequency drive (VFD) inverter. Unlike traditional pumps that run at a constant speed, VFD pumps continuously adjust motor speed to match real-time water demand. T400/T600/T800/T1000 series deliver constant water pressure with up to 40% energy savings, soft start/stop to eliminate water hammer, and smart protection against dry-run, over-pressure, and power anomalies.

Intelligent VFD Control
Built-in inverter with PID controller maintains constant pressure. LCD display panel for easy setup and monitoring.
40% Energy Savings
Permanent magnet motor achieves IE5 efficiency class. Automatic speed reduction during low demand saves electricity.
Soft Start & Soft Stop
Gradual ramp-up eliminates water hammer and inrush current. Extends pump, pipe, and valve service life.
Multi-Protection System
Over-voltage, under-voltage, over-current, dry-run, and phase-loss protection built into the VFD controller.

— FREQUENTLY ASKED QUESTIONS —
How much energy can I save with a VFD pump?
Typical energy savings range from 20-40% compared to fixed-speed pumps, depending on your usage pattern. The T Series permanent magnet motor alone is 8-12% more efficient than standard induction motors.
What is constant pressure control?
Constant pressure control means the VFD pump automatically adjusts speed to maintain the same water pressure regardless of how many outlets are open. No pressure fluctuations, no temperature swings in showers.
Can I connect the VFD pump to my building management system?
Yes. T Series models include communication ports for integration with BMS and SCADA systems. Remote monitoring of pressure, flow, and fault diagnostics is available.
Do VFD pumps require special installation?
VFD pumps install like standard pumps but require adequate ventilation around the controller and proper electrical grounding. The built-in controller simplifies installation by eliminating external pressure switches and control panels.
