The QB 2.5hp 1-Speed Fine Thread (1850 W) AMP Spa Pump is a high-powered spa pump designed for spas and swim spas that require strong circulation and powerful hydrotherapy jets. Its fine-thread union connections make it suitable for systems originally plumbed with fine-thread fittings, allowing a direct replacement without the need for adaptors or re-plumbing.

Equipped with a robust 1850 W motor and a durable moulded wet end, the pump provides consistent high-volume water flow for multi-jet spas and swim-spa applications. The AMP-style plug ensures seamless integration with Australian spa controllers and equipment systems.
