Product Description

When matching pumps always use AMPERAGE rather than Horsepower. Many times the labeled Horsepower does not accurately represent actual horsepower.

The Executive 56 Frame Spa Pump has an executive wet end designed for 56-Frame motors along with two double-shielded ball bearings with moisture-resistant grease for quieter operation and long life. The dual speed motors have insulated windings for increased efficiency and large, highly versatile 6-1/2" diameter wet end for higher head pressure. A split capacitor (start and run) allows for less energy consumption.

Spa Pump Features:

  • Executive wet end designed specifically for 56-frame motors
  • 56-frame motor for added strength, cooler operating temperature, and longer motor life
  • Large 6-1/2" diameter wet end for higher head pressure
  • 2" intake for improved flow performance and reduced noise
  • Wet end can be rotated for easy installation
  • Two double shielded ball bearings with moisture resistant grease for quieter operation and longer life
  • Two speed motors have four sets of insulated windings for increased efficiency
  • Dimensions (H x W x L): 9.08" x 8.05" x 14.775"
  • Available in 1 to 5Hp and in single or dual speed 

  • California Title 20 Compliant

Hello Bill.  The Waterway Executive 56 Spa Pump model 37212211D is a compatible replacement for the Waterway Executive Spa Pump model 3721221-OD6BMR.

Would this be a good pump to use for some water features that are going to require like 130 GPM? I don't understand the disadvantage of this pump, it seems to deliver a ton of output even at a relatively high head. Why is it called a "spa pump"?

A  Answered on 2/28/2019 by InyoPools Product Specialist Steve M.

Yes, depending on the total feet of head, this pump would be more than sufficient. This is considered a spa pump because it produces high HP and pressure, perfect for spa jets. Additionally it has side discharge ports which are not compatible with most pool systems. The last thing is that this pump is a little smaller and take up less space so it can fit inside of certain spa spaces.
