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 (SEE THE AVAILABLE STYLES TAB)

  • California Title 20 Compliant

My motor is leaking around the shaft between wet and dry, what are my options for that problem? The model number is C55MWKBT-4824

A  Answered on 6/9/2020 by InyoPools Product Specialist Hector F.

Most often these leaks are caused by failed seals and gaskets but in order to confirm which ones you will need, you will need to know the specific pump make and model.

I need a replacement for a Cal Spa hot tub (GE Motor Model 5KCR49WN2370AX).

Hi James, Could you send us a few photos of your pump and motor? Please take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

Can the wet end be rotated 90 degrees, this one points straight up and my connection is on the side 1/4 turn to hit my existing spa connection

A  Answered on 4/28/2020 by InyoPools Product Specialist Patrick P.

Hi Dave, Yes this can be rotated so the discharge port is at 90 degrees.

I am trying to match up my old pump, it is an Executive 56 5HP 230V 12.0/4.4amps, Part # PF-40-2N22C

A  Answered on 4/28/2020 by InyoPools Product Specialist Patrick P.

Hi Dave, You will actually need this 3721621-1D Waterway Spa Pump we have this pump in stock ready to ship!

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

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.

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.

A  Answered on 2/10/2015 by InyoPools Product Specialist Robert M.

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.
