Zilmet ZPP 12/40 2.2kW VSD booster pump 220V – High Flow VSD

Zilmet ZPP 12/40 2.2kW Variable Speed Pressure Booster

The Zilmet ZPP 12/40 VSD booster pump is a powerful 2.2kW variable speed drive pump designed for applications requiring high flow rates with consistent pressure. The integrated VSD controller automatically adjusts pump speed based on demand, reducing energy usage, minimising pressure fluctuations, and extending pump life.

According to manufacturer technical data, the ZPP 12/40 delivers a maximum flow of 18 m³/h, with a rated operating point of 12 m³/h at 40 metres head, making it suitable for multi-outlet residential systems, irrigation boosting, and light commercial water supply.

Operating on 220V ±20% at 50/60 Hz, the pump reaches a maximum motor speed of 4500 rpm, allowing it to adapt dynamically to changing demand while maintaining system efficiency

Performance Overview.

• Designed for high-flow applications
• Optimised operating region around 12–18 m³/h
• Stable pressure delivery across variable demand ranges

Typical Applications

• Large residential homes
• Multi-bathroom pressure boosting
• Irrigation system boosting
• Small commercial water supply
• Rainwater harvesting systems (with correct filtration)

Sizing Guidance

Choose the Zilmet ZPP 12/40 VSD booster pump when:

• System flow demand exceeds 10 m³/h
• Operating pressure requirement is around 40 metres head
• Multiple outlets may run simultaneously
• Variable demand requires pressure stability

For smaller homes or lower flow demand, consider lower ZPP models.

Operating & Duty Recommendations

• Designed for automatic pressure-controlled operation
• Best efficiency achieved near rated flow and head
• Install with adequate suction conditions and filtration
• Electrical protection must comply with local regulations
