SPS-90Intelligent VFD Booster Pump
The SPS-90 is the quietest pump in the Calliope range, built for apartments and small homes where the pump sits close to living and sleeping rooms. Five selectable power stages, from 0.18 to 0.38 kW, cover 47 to 60 L/min and 17 to 32 m of head, so one model replaces several fixed-speed sizes. A water-cooled, fanless permanent magnet motor, a ceramic shaft and a ceramic bearing hold noise to 40 dB or less, while 7 m of suction lift lets the pump draw from a tank below it.

Key benefits
SPS-90 Intelligent VFD Booster Pump · data from the 2026 catalog and the model page.
- Quietest model in the range at 40 dB or less — water-cooled fanless motor with a ceramic shaft and bearing, made for rooms beside bedrooms and bathrooms.
- Five power stages (0.18–0.38 kW) span 47–60 L/min and 17–32 m, so a distributor stocks one model instead of several fixed-speed sizes.
- 7 m suction lift draws from a rooftop tank or a cistern below the pump, not only from pressurised mains.
- Compact 5.4 kg body with 3/4-inch ports fits a utility space or an outdoor cabinet.
Saves 60% or more energy than a same-power conventional fixed-speed pump at the same flow/head duty point under constant-pressure conditions.
