The I-Prez Booster System with VFD is a smart domestic and light commercial pressure-boosting system designed to provide constant water pressure in the pipeline. It uses a built-in Variable Speed Drive / VFD to adjust pump speed according to water demand, helping reduce pressure fluctuations, improve comfort and save energy.
The system uses a pressure transducer to monitor pressure constantly and regulate performance. It includes a horizontal multistage pump, VSD, 5-way connector with built-in non-return valve, pressure tank, pressure gauge and pressure transducer.
A float switch is available as an optional extra.

Typical Applications
The I-Prez Booster System is suitable for:
- Domestic water supply

- Pressure boosting from storage tanks
- Garden water supply
- Small buildings
- Schools
- RO system feed water
- Light commercial clean-water pressure boosting
Why Choose a VFD Booster System?
A normal fixed-speed booster pump switches on and runs at full speed, even when only a small amount of water is required. The I-Prez VFD system adjusts pump speed according to demand, which gives smoother pressure, reduces unnecessary energy use and places less strain on the pump.
This makes it a strong option for customers who want steady pressure, quieter operation and better efficiency than a basic booster pump.
Important Use Note
The I-Prez Booster System is designed for clean water only. It should not be used for dirty water, sewage, pool water, slurry, sand-heavy water, chemicals, fuel, oil or flammable liquids.
For best performance, install the system with correct pipe sizing, inlet filtration, dry-run protection where required, and professional electrical connection.
