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
  • 2-1/2" 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

i need to replace a pump and motor, which one do i need. old item: part # 8 -187563-02 (RPM3450/1725

Based on that model number the replacement motor would be part number B235. Now if you need the complete pump then we would need the specific model number or name of the front pump housing that the motor bolts to, You can provide that information or images of it if you are not sure through our support request page if you need further assistance.

What is the amp rating for this motor? Will this replace my 2 speed/230v Intertech motor and pump on my Jacuzzi spa? The Intertech amp rating is 12/4.4 amps. What's the difference between a 48 frame and a 56?

A  Answered on 10/23/2017 by InyoPools Product Specialist Lennox H.

Hi. The amp rating of this pump is 12.0/4.4 at 230 volts. The difference between a 48Y and 56Y frame is the diameter of the motor body. The 56Y motor is larger than a 48Y frame motor. This pump can be used depending on the Intertech Pump model and configuration.

I need to replace my spa pump and motor. My old part is a century lasar pool/ spa cat BN62 part number 7-184821-04 frame y48y. What model do I need?


A  Answered on 11/23/2020 by InyoPools Product Specialist Megan C.

The Century 3.0 HP Thru-Bolt 48Y Dual Speed Low Amps Motor - BN62 is available for order. To suggest a whole pump, we will need to see images of the spa pump wet-end or provide the model name or number off of it.

A  Answered on 4/24/2020 by InyoPools Product Specialist Patrick P.

Hi Dave, The discharge on this pump can be rotated so it goes out the side. Could you email us a few photos of your pump? As this could help us reccomend the proper replacement. To supply the photos simply click the reply link below to upload your photos.
