Flow and electrical figures are manufacturer specifications. Flow in an installed pool depends on plumbing resistance, operating head, system configuration and selected speed. Confirm pump sizing, electrical requirements, connection compatibility and automation wiring with the installation manual and a qualified installer. The published noise and performance specifications can vary with operating conditions and supply voltage.

Choosing the Right InverFLOW PLUS V2 Pump

Select a pump by comparing the manufacturer's performance curve with the flow your pool equipment requires at its actual operating head. Horsepower alone is not enough to confirm suitability. Check filter limits, heater and cleaner flow requirements, plumbing size, electrical supply and automation compatibility before choosing a model.
