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"

What kind if connector is on the plug? My pump has 3 round pins in a diagonal (/) pattern and 1 flat pin that plugs into a LA Spas control center.

Hello John - The pump does not come with a cord. You can take the cord off of your old pump and attach it to the new pump.

Mark : The spa pump has 6HP tag on it, and the following numbers in the plastic casting 311-1239-DNB - 311-1200. The motor part # is 3721621- OD76.Waterway Model PF-30-2N22M. Which one would be the right pump, motor combination to replace it with? Thanks: Ray

A  Answered on 6/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Ray. Most spa pumps are specially labeled. Based on the info provided the Waterway Executive Pump 4 HP 230V 2-SD - 3721621-1D is the replacement.

Good Morning Mark...…. I am looking for the front portion of the wet end. #s 311-1239-DNB and 311-1200. I've located it, but mine has two nipples in the front for hoses. What I have found only has plugs in those location. The plugs also seem to be non removable. Will you please give me your educated advice. Thank You .

A  Answered on 6/7/2019 by Industry Professional

You can remove the plugs and insert the adapters for the two nipples.

A  Answered on 6/7/2019 by Industry Professional

Due to mfg design changes we actually recommend that you change the complete wet end & not just the faceplate. The original faceplate used 1 o-ring & the newer style uses 2 o-rings on the faceplate. We have spoken with customers that have had issues making the newer style work with the older style volute. Just an FYI. The bleed plugs are removable & the part #'s for the barb replacement plugs are 9404-01 & o-ring # 4600-4661
