About this spa pump

This LX WTC50M-USA is a 1/3 HP single-speed main circulation pump designed for 230V spa systems requiring 1-1/2" MBT (male buttress thread) connections. Built with a 48Y frame configuration, this reliable pump delivers consistent water circulation for residential hot tubs and spas. The 230-volt operation ensures efficient performance while maintaining quiet operation during extended run cycles.

At Bubbles Supply, we guarantee this LX pump provides an exact fit replacement for your existing circulation system. Every pump ships the same day when ordered before our cutoff time, and we back each unit with our comprehensive 1-year warranty for complete peace of mind. Before installation, verify your spa's voltage requirements match 230V and confirm the 1-1/2" MBT thread sizing on your existing plumbing connections to ensure proper fit.
