Description
This OEM 4HP Waterway Viper dual-speed spa circulation pump features 2-1/2" x 2-1/2" plumbing connections with a 56-Frame motor configuration. Thread-to-thread spacing measures 3 11/16" on both suction and discharge ports. This specialized pump model appears primarily in Coast brand hot tubs, various swim spa installations, and select manufacturer models where standard pumps won't fit.
The 230-volt two-speed motor combines with Waterway's proprietary Viper wet end engineering to deliver exceptional hydraulic performance. Double-shielded ball bearings contain moisture-resistant lubrication for whisper-quiet function and extended service life. The 6-1/2" diameter wet end generates superior head pressure while dual-speed operation provides energy-efficient spa operation.
