LX Pump Circ

The LX Whirlpool WTC50M filtration pump is a 24-hour circulation pump. It is the only pump manufactured by LX Whirlpool which turns at half-speed (1450 rpm), and as a result it is much quieter other LX Whirlpool pumps of similar power, like the JA35 circulation pump.

This pump is not the same as as the WTC50M-A (part numbers 6500-920 and 6500-910) and WTC50M-B (6500-067) models which are manufactured exclusively for Sundance Spas, depite the similar model numbers. You can install a WTC50M in place of a WTC50M-A or B, but not without difficulty. The alignment of the suction and return fittings is slightly different, and you will have to modify the plumbing of your hot tub, which is never easy.
