Delivering up to 92 L/min and 320 kPa, this vertical multistage pump is ideal for domestic water supply, irrigation, garden watering, rainwater harvesting, or sump/tank emptying applications.

Built with a corrosion-resistant stainless steel motor casing and precision-moulded polymer internals, the TankBuddy ensures long-lasting efficiency and low-maintenance performance. Its compact size allows for discreet in-tank installation, and when paired with an Onga MiniPress or WaterSwitch controller, it becomes a fully automatic household pressure system complete with loss-of-prime protection and consistent water pressure.
