Speroni VSD Auto Pressurisation System | 1.1kW 230V

This is a strong upgrade from a standard pump-and-controller setup. Instead of switching harshly on and off at full speed, the Speroni VSD system uses pressure feedback to adjust pump speed in real time. This helps improve comfort at taps and showers, supports efficient operation and reduces unnecessary strain on the pump and pipework.

Best For

• Domestic clean-water pressure boosting
• Tank-to-house water pressure systems
• Homes needing more stable pressure at taps and showers
• Garden and civil irrigation applications
• Small properties and light commercial clean-water systems
• Customers upgrading from a basic pump and pressure controller
• Installations where energy efficiency and pump protection are important

Premium Benefits

• Constant pressure: adjusts motor speed to maintain steadier outlet pressure
• Energy saving: variable-speed operation can reduce energy use compared with traditional fixed-speed water supply systems
• Soft start and soft stop: reduces harsh pump starting and helps limit water hammer
• Dry-run protection: helps protect the pump when water supply is insufficient
• Reduced pump wear: lower average operating speed can reduce strain on the shaft and pump components
• Compact design: suitable where a modern, space-saving pressure booster is required
• Simple operation: one-button style operation makes setup easier for installers and users
• Better pressure comfort: useful for showers, taps, garden points and pressure-sensitive applications

Suitable Applications

• Domestic water pressure boosting
• Water tank to house supply
• Garden taps and civil irrigation
• Small and medium property water pressure systems
• Clean-water booster applications where pressure stability is required
• Upgrades from standard fixed-speed pressure pumps

Not Suitable For

• Dirty water, grey water, sewage or sludge
• Water containing sand, grit or abrasive particles
• Hot water circulation
• Deep borehole pumping unless specifically confirmed for the selected installation
• Large engineered commercial systems without technical sizing
• Installations where the pump may run dry without a reliable water source

VSD Booster vs Standard Pump & Controller

Feature	Speroni VSD System	Standard Pump + Controller
Pressure control	Adjusts speed to maintain constant pressure	Basic on/off operation
Energy use	Can save energy by matching speed to water demand	Usually runs at full speed when on
Start/stop behaviour	Soft start and soft stop	More abrupt switching
Pipe protection	Helps reduce water hammer	More likely to create pressure shocks
Best for	Premium pressure comfort and efficiency	Budget pressure boosting

Before You Buy, Confirm

• Water source: tank, municipal backup, borehole storage or other clean-water source
• Number of bathrooms and taps
• Number of storeys
• Pipe distance from tank to house
• Required pressure at outlets
• Garden or irrigation requirement
• Electrical supply and installation position
• Whether filtration is required before the pump

What’s Included

• Speroni VSD auto pressurisation system
• Integrated inverter / variable speed control
• Pressure sensing and automatic pressure regulation
• Protection and control system

Note: Included accessories and fittings may vary by model. Confirm whether additional valves, unions, filters, fittings or installation accessories are required for your system.

Frequently Asked Questions

What is a VSD pressure pump?

A VSD pressure pump uses variable speed control to adjust motor speed according to water demand. This helps maintain steadier outlet pressure than a basic fixed-speed pump.

Does this pump save electricity?

Variable-speed systems can reduce energy use in suitable installations because the motor does not always need to run at full speed. Actual savings depend on the installation, pressure setting and water demand.

Is this better than a normal pump and controller?

For customers who want smoother pressure, soft start/stop operation and improved pressure comfort, a VSD pressurisation system is usually the better option. A normal pump and controller is generally the more budget-friendly option.

Can this be used from a water tank?

Yes, it can be suitable for tank-to-house clean-water pressure boosting when correctly installed and sized.

Does it protect against dry running?

The Speroni VSD system includes dry-run protection features, but a reliable water source and correct installation are still essential.

Can it handle dirty water?

No. It is intended for clean water only and should not be used with sand, sludge, grey water, sewage or abrasive liquids.

Is professional installation recommended?

Yes. Professional installation is recommended to ensure correct sizing, pipework, pressure settings, electrical safety and pump protection.
