Astralpool Pump Motor 1500W SP71619 (Black Notos, Slinger) - CTX 500, BX 2.0, FX 520, XP 2.0
This is the genuine Astralpool 1500W single phase pump motor, part number SP71619: the black Notos motor, supplied with a slinger on the shaft. Fluidra describes it as the Motor 1500W Black Slinger. It replaces 71319, the 1500W motor number in Astralpool's pumps manual H0717800, and fits the pumps built with that motor: CTX 500, BX 2.0, FX 520 and XP 2.0. One motor per pump.
- Physically Stocked, unlike most "drop-shipping" websites.
- Shipped from VIC, NSW, WA, QLD
Confirmed Compatibility
Astralpool's pumps manual H0717800 lists motor 71319 for the CTX, FX and XP models below. Astralpool's BX spare parts list includes the same black motor, and Astralpool dealers list it for the BX model below:
- CTX 500
- BX 2.0
- FX 520
- XP 2.0
XP figures are for the single phase models. The XP 2.0 three-phase takes motor 71335.
Not this motor: SP71613 (750W) for the CTX 280, CTX 360, BX 1.0, FX 250, FX 290 and XP 1.0; SP71614 (1100W) for the CTX 400, BX 1.5, FX 340 and XP 1.5. The CTX 180, FX 190 and E-Series take the 750W mini motor 71310. 3 HP single phase pumps take 71331, and three-phase pumps take a three-phase motor. The Viron variable speed pumps take a brushless DC motor.
Ask first: replacing a beige Fasco 1500W motor (71329)? Fluidra lists different fans, cowls and capacitor box lids for the beige Fasco and black Notos motors, so send us a photo of the old motor and its data plate first. Ask first too for any pump not listed above.

The Black Notos Motor Rule (rev. BN1500-1.0)
Confirm this motor by the pump and the data plate:
- Read the pump badge. CTX 500, BX 2.0, FX 520 and XP 2.0: this is your motor, per Astralpool's pumps manual H0717800 (the BX per Astralpool dealers).
- Read the motor data plate. The black Notos motor numbers are 71313 or SP71613 (750W), 71314 or SP71614 (1100W) and 71319 or SP71619 (1500W). 71319 or SP71619 is this 1500W motor. Match the wattage on the data plate.
- Beige motor? Ask first. A beige motor (71329 for 1500W) takes different fan, cowl and capacitor box parts. Send us a photo before ordering.
- Check the wet end while it is apart. Inspect the mechanical seal, seal plate and O-ring, and the impeller, when the old motor comes off. A seal left leaking lets water reach the new motor.
- Unsure? Ask first. Send us a photo of the pump badge and the motor data plate, and we will confirm the motor before you order.
The Three Black Notos Motors
| Black Notos motor | Pumps fitted with it |
|---|---|
| 750W, 71313 (now SP71613) | CTX 280, CTX 360, BX 1.0, FX 250, FX 290, XP 1.0 |
| 1100W, 71314 (now SP71614) | CTX 400, BX 1.5, FX 340, XP 1.5 |
| 1500W, 71319 (now SP71619, this motor) | CTX 500, BX 2.0, FX 520, XP 2.0 |
Motor numbers for the CTX, FX and XP are from Astralpool's pumps installation manual H0717800. Astralpool's BX spare parts list includes the same three black motors, and Astralpool dealers list them for the BX 1.0, 1.5 and 2.0. XP figures are for the single phase models. Some older pumps of these models were built with a different motor (a beige motor on older CTX and BX pumps, a CMG motor on older CX, TX and FX pumps), so go by the motor fitted, not the pump badge.
What Slinger Means
Fluidra describes this motor as supplied with a slinger. A slinger is a ring on the motor shaft that throws off water tracking along the shaft before it can reach the front bearing. It does not replace the mechanical seal: a leaking seal still needs to be replaced.
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.

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 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
| 4" BSP | 113.03 mm / 4.450" | 11 |
| 5" BSP | 138.43 mm / 5.450" | 11 |
