Onga Tankbuddy OTB450A 0.65kW Submersible Pump with Automatic Float Switch (Max 84LPM/270kPa)

The Onga Tankbuddy OTB450A is a high-performance submersible pump designed for clean water applications in domestic and light commercial settings. With its built-in automatic float switch, this model offers hands-free operation—starting and stopping the pump as water levels rise or fall—making it an ideal solution for sump and tank emptying, water transfer, or rainwater harvesting systems.

Capable of delivering up to 84 litres per minute and a maximum head of 27 metres, the OTB450A runs completely silent while submerged, making it perfect for use in residential environments. Its stainless steel construction provides exceptional corrosion resistance, while precision-moulded internals ensure high efficiency and a long service life.

When paired with a Minipress or WaterSwitch, it becomes a fully automatic pressure system, complete with dry-run protection and consistent pressure delivery throughout the home or garden.
