Wilo SE, headquartered in Germany, produces some of the most advanced hydro-pneumatic booster systems available in India. Their multi-pump booster sets with integrated VFD cascade control deliver constant pressure regardless of demand fluctuation — critical for hospitals, five-star hotels, and high-rise residential towers.
Simplex, Duplex, and Triplex Configurations
- Simplex: Single pump with pressure vessel — suitable for small commercial buildings
- Duplex: Two pumps, lead-lag operation — one pump handles base load, second kicks in during peak demand. True redundancy.
- Triplex: Three pumps with full cascade — no single point of failure. Specified for hospitals and critical infrastructure where pressure failure is unacceptable.
VFD Cascade Advantage
Traditional booster systems use pressure switches to start/stop pumps abruptly, causing water hammer and pressure spikes. Wilo's VFD-controlled cascade ramps motor speed smoothly, eliminating hammer, reducing pipe stress, and saving 30–50% energy vs fixed-speed systems.
