VFI10-5 – 3kW VSD Booster Pump |
3kW VSD Booster Pumps for Constant Water Pressure
The VFF12-50B and VFI10-5 are powerful 3kW variable speed drive booster pumps designed to maintain stable water pressure for homes, lodges, complexes, estates and commercial buildings.
These pumps use variable speed drive technology, also known as VSD, VFD or inverter control, to automatically adjust the motor speed according to water demand. This helps maintain constant pressure while reducing unnecessary power usage.
Applications
- Residential homes
- Lodges and guest houses
- Complexes and estates
- Commercial buildings
- Industrial clean water boosting
Key Benefits
- Constant pressure as water demand changes
- Energy efficient variable speed operation
- Soft start and stop to reduce water hammer
- Stainless steel wet-end
- Digital pressure control and display
- Compact booster pump design

Important Installation Note
These booster pumps must be supplied from a suitable water storage tank or header tank. They should not be connected directly in-line to municipal water supply. Correct suction pipe sizing, short suction runs and unrestricted pipework are important for reliable pump performance.

Frequently Asked Questions
Can these pumps be connected directly to municipal water?
No. These booster pumps must be supplied from a water storage tank or header tank. Direct connection to municipal water supply is not recommended and can cause dry-run problems, poor performance and possible pump damage.
What is the benefit of a VSD booster pump?
A VSD booster pump automatically adjusts motor speed according to water demand. This helps maintain constant pressure, reduces power usage and gives smoother starting and stopping.
What voltage do these pumps require?
Both models listed on this page are 3kW, 380V three phase, 50Hz booster pumps.
Which pump is better, the VFF12-50B or the VFI10-5?
The correct pump depends on the required flow and pressure. The VFF12-50B has a 50mm inlet and outlet and is suited to higher flow applications. The VFI10-5 has a higher maximum head and is better suited where higher pressure is required.
