Astralpool Pump Motor 2200W 3 HP Single Phase 71331 (Black) - XP 3.0, CTX 610, BX 3.0
This is the genuine Astralpool 2200W (3 HP) single phase pump motor, part number 71331. Fluidra describes it as the Motor 2200W Black. Astralpool's pumps manual H0717800 lists 71331 as the 3 HP motor for the XP 3.0 single phase, and dealers list it for the CTX 610 and BX 3.0 as well. Astralpool's 2014 CTX and BX spare parts lists and 2017 CX list describe 71331 as beige; Fluidra now supplies it in black. One motor per pump.
- Physically Stocked, unlike most "drop-shipping" websites.
- Shipped from VIC, NSW, WA, QLD
Confirmed Compatibility
XP 3.0 single phase: motor 71331 in Astralpool's pumps manual H0717800. Pump rating: 240V single phase, 2300W, 3.00 HP, 12.5A.
CTX 610 and BX 3.0: listed for 71331 by Astralpool dealers. 71331 is on Astralpool's 2014 CTX and BX spare parts lists as the 2200W motor.
Fluidra lists cooling fan 40275 and fan cowl 40274 for its Notos 3 HP and Notos three-phase motors, and cowl 40262 for its Fasco 2400W 3 HP motor. Fluidra's motor spare parts list gives the 3 HP bearing as 6204 (47 mm outside diameter, 20 mm bore, 14 mm wide).
Not this motor: three-phase pumps take a three-phase motor: 71320 (XP 1 HP three-phase), 71335 (XP 2.0 and XP 3.0 three-phase) or 71338 (XP 4.0). 750W to 1500W single phase pumps take SP71613, SP71614 or SP71619, and the CTX 180, FX 190 and E-Series take the mini motor 71310.
Ask first: CX pumps (Astralpool's 2017 CX list shows 71331 as a beige 2100W motor), and any 3 HP pump with a beige motor, because the fan and cowl differ. Send us a photo of the motor and its data plate.

The 3 HP Motor Rule (rev. N3M-1.0)
Confirm this motor by the supply, the pump and the data plate:
- Single phase or three-phase? A 240V single phase 3 HP pump takes 71331. A 415V three-phase pump takes a three-phase motor (71320, 71335 or 71338 on Astralpool's XP list).
- Read the pump badge. XP 3.0 single phase: 71331 in Astralpool's pumps manual H0717800. CTX 610 and BX 3.0: listed for 71331 by dealers.
- Beige or black motor? Astralpool's older lists describe 71331 as beige, and Fluidra lists different fan cowls for its Notos 3 HP (40274) and Fasco 2400W 3 HP (40262) motors. Send us a photo of a beige motor before ordering.
- Check the wet end while it is apart. Inspect the mechanical seal, seal plate, O-ring and impeller when the old motor comes off.

Before You Replace the Motor
Before condemning the motor:
- Pump noisy or humming: the cause can be the impeller, bearings, mechanical seal or capacitor as well as the motor itself. Have it diagnosed before buying a motor.
- Pump not running: something may be stuck in the impeller. With the power isolated, check whether the impeller can move freely. If it does not move, something inside needs removing; if it does move, the motor may have failed.
- Damaged basket: debris can pass through a broken basket to the impeller and jam the pump.
Check regularly for leaks under the pump. A seal that is left leaking lets water reach the motor, so check the seal, seal plate and O-ring whenever the motor is off.

Fitting Notes
Isolate the pump at the switchboard before any work. Astralpool's pump manuals say the pump must be installed and serviced by a licensed electrician in accordance with AS/NZS 3000.
- Photograph the old motor's data plate and wiring before disconnecting anything.
- Separate the motor from the wet end and inspect the impeller, mechanical seal, seal plate and O-ring.
- Fit a new mechanical seal if the old one was leaking or is worn, and check the seal plate for cracks.
- Reassemble with the correct impeller for the pump model, then have the electrician connect and test the motor.
Frequently Asked Questions
Which pumps does the 71331 motor fit?
Astralpool's pumps manual H0717800 lists 71331 as the 3 HP motor for the XP 3.0 single phase. Dealers also list it for the CTX 610 and BX 3.0, and it appears on Astralpool's 2014 CTX and BX spare parts lists as the 2200W motor.
Is 71331 beige or black?
Both have been supplied under this number. Astralpool's 2014 CTX and BX lists describe it as beige, and Fluidra now describes it as the Motor 2200W Black. The fan and cowl differ between motor types, so send us a photo of your old motor before ordering small parts.
My XP 3.0 runs on three-phase power. Is this the motor?
No. Astralpool lists 71335 for the XP 3.0 three-phase (415V). 71331 is the single phase 3 HP motor.
Which bearings does a 3 HP motor use?
Fluidra's motor spare parts list gives the 3 HP bearing as 6204, 47 mm outside diameter, 20 mm bore and 14 mm wide.
Is this a genuine Astralpool part?
Yes. Heater and Spa Parts is an authorised Fluidra (Astralpool and Zodiac) dealer and warranty agent, and 71331 is the genuine Astralpool part, barcode 9343609057060.
Can I fit the motor myself?
No. Astralpool's pump manuals say the pump must be installed and serviced by a licensed electrician in accordance with AS/NZS 3000. As with all of our products, it must be diagnosed and fitted by a qualified and experienced person.

To the layperson, plumbing sizes and their names can be confusing due to the nominal sizes and naming conventions used.
This is not something we made up. Plumbers and manufacturers have used nominal (meaning ‘by name only’) sizing for decades.
Simply put, in plumbing, named sizes are often not the actual measurements of the pipe, fitting, or part. A PVC pipe called “50mm” or “2"” does not measure 50 mm anywhere. Instead, it follows nominal sizing, an internationally-standardised naming system.
Almost all fittings we use in the pool & spa industry use “pressure PVC” pipe & fittings. Do not confuse with “DWV” or other pipe & fittings and their names and sizes.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1/2" | 15mm | ~21.2–21.5 mm |
| 3/4" | 20mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
To reiterate, these are nominal sizes and are designed to fit matching fittings — not to measure what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions1.
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems and other plumbing areas so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate.
Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
