More Information

The Waterway Executive 56-frame 4HP Dual-Speed Spa Pump is designed with both low and high speed for versatility and energy efficiency. Along with a 56-frame motor and an executive wet end, it features two double-shielded ball bearings, complete with moisture resistant grease for silent operation and better performance.

Four sets of insulated windings increase efficiency, along with its split capacitor for less energy consumption. It uses a 2-1/2" intake for improved flow performance, and its side-discharge wet end is rotatable by 90 degree increments for flexibility. Its wet end measures 6-1/2" in diameter for higher head pressure, and is thermally protected for higher motor life expectancy. At 230 volts and drawing 12/4.4 amps, it promises resilience and trustworthy operation.

the Item came quick and was exactly what I needed, and worked great for a few days, but this one unit has some issues, started making noise and or would not star up and cause the relay on the control to kick off. Seems the bearing could be an issue or the switch in the pump. Working with elctronisc etc.. for many yrs it can happen. NOT FUN So far I was requested to work with Waterway Techs on the phone and they also deemed it defective. I had to take Pic and re-contact Pool supply to get The RMA .. more

The pump was exactly what I needed - It arrived way before they said it would . This was for above ground Morgan spa that is used by two ladies age 69 and 90. We had to wait for a neighbor to install and then after it was in stalled the thermostat in the housing was bad. So now waiting on neighbor to come back and replace the thermostat. The spa is still under warranty but Morgan is literally out of business. As far as Pool supply world they are great.

Was exact duplicate of the pump that went bad, and at about half the price. Was delivered when they quoted. Very good transaction and whenever we need spa parts or supplies, definately will look here first.
