Pump assembly complete with Waterway Hi-Flo wet end. Popular on CalSpas, Dimension One Spas, and many others. This is a 2inch suction and discharge pump.  The male union threads on a 2 inch pump measure 3 inches!!!! check yours closely. If your male theads measure 2.5 inches your pump uses 1.5 inch union fittings and this is not the pump you need! The pump wet end will have 8 phillips head screws in the faceplate. Side discharge, can be rotated to any of 4 positions in minutes. This is a new pump assembly.

This pump is only offered as a 2 speed.  If you have a single speed pump you can still use the 2 speed version.. you will just connect the high speed leg ONLY when wiring.

Note that your pump may say 5 HP, (5 horsepower) but what you want is actually a pump voltage and amperage rating that closely matches yours. This is an unfortunate consequence of marketing horsepower in this industry.

  Misleading, but you can get the right pump simply by selecting the 4HP option. Any questions regarding pump selection please call us! Choose your configuration from the options below.

Often found with the 'Niagara' model label.
