QB 2.5hp 2spd (1850w) AMP
Description

The QB 2.5HP Two-Speed Spa Pump is a versatile, high-performance spa booster pump designed for reliable everyday use in Australian spas and swim spas. Built on the trusted QB Series platform by Davey, this pump delivers the perfect balance of power and efficiency—strong jet pressure when you want it, and economical circulation when you don’t.

With two-speed operation, the pump runs quietly on low speed for heating and filtration, then switches to high speed to provide invigorating hydrotherapy. Featuring 50mm fine thread unions and supplied with an AMP plug, it can be used as a direct replacement for many LX and other branded spa pumps, making it an ideal choice for straightforward upgrades or replacements.
