SPS-90

Name: SPS-90 Intelligent Inverter Booster Pump
Brand: Calliope Pumps
SKU: SPS-90

Five-stage permanent magnet inverter booster that holds a steady outlet pressure for whole-house and villa water supply.

The SPS-90 uses permanent magnet frequency conversion with five selectable power stages, so one model covers the duty of several fixed speed sizes. Outlet pressure stays constant as taps, showers and appliances open and close, and the ceramic shaft and bearing keep running noise low. Intelligent diagnosis reports alarms early and the compact body fits into a utility space or outdoor cabinet.
