Electronic Control Pump — Model Range

Choosing a WQ_B, HQ_B or TQ_B Electronic Control Pump

An electronic control pump combines the pump, motor, a pressure tank and an electronic controller in a single unit. The controller starts the pump when water is drawn and keeps it running until demand stops, giving more even pressure at the taps than a simple pressure switch arrangement. This page lists three series, each in a standard version and an anti-microbial version marked with a B suffix.

The TQ_B series is the widest, running from the 0.18 kW TQ200 to the 3.7 kW TQ3700, with 1 inch ports on the smaller models and 2 inch ports from 1.5 kW. Larger TQ_B models are available in single and three-phase versions and reach up to 52 m head and 270 L/min at 60Hz. TQ_B has built-in dry-run and cycling protection. The HQ_B series covers 0.18 to 0.75 kW, with dry-run shut-off and automatic reset, protection against repeated starting caused by a dripping tap, and suction lift up to 7.6 m; the HQ800H gives up to 45 m head. The WQ_B series also spans 0.18 to 0.75 kW at 50Hz, with up to 125 L/min.

Preset start pressures range from 1.2 to 3.0 kg/cm² depending on model, so choose by the flow and pressure needed at the furthest outlet.
