Check compatibility before ordering
Requires three-phase power. Not suitable for a standard single-phase electrical supply. Have a qualified pool professional verify voltage, electrical phase, plumbing and hydraulic requirements before purchase. Professional installation is required and is not included. Follow the manufacturer's installation instructions.
Performance and system fit
Choose this pump for the flow your circulation system actually requires. Horsepower alone does not tell you how much water will move through the installed plumbing. Compare the pump curve at your system's operating head, then check the filter's flow limit and the minimum flow required by connected equipment.
Electrical and control requirements
This is a three-phase model. Confirm that three-phase power is available; it is not a direct electrical replacement for a typical single-phase residential pump. Use the control configuration specified in this listing; confirm any additional interface needed for your existing automation system.
Installation and routine care
Check the suction and discharge connection sizes, available equipment-pad space and access to the strainer lid. Plumbing adapters, additional automation accessories and installation labor are separate unless expressly included above. Have a qualified installer set up the pump, confirm priming and establish suitable operating settings. Keep the basket and filter clean and investigate changes in flow or noise.
Compatibility & installation
Check the exact model and the specifications above before ordering. For equipment and replacement parts, confirm the required voltage, connections, dimensions and compatibility with your existing system.
