Reltech SunSol SS100 Pump - Astralpool E230 Retrofit - 1.0hp
Reltech SunSol SS100 Pump - Astralpool E230 Retrofit - 1.0hp is temporarily out of stock and will ship as soon as it's available.
The Reltech SunSol SS 100 1.0HP pool pump is a high-quality AstralPool E230 retrofit pump, commonly used as a replacement for older AstralPool and Hurlcon pump models where a reliable single-speed pump is still preferred.
Australian made. Not a cheap Chinese knock-off.
The Reltech SunSol SS Series is Australian made and built for harsh local conditions. These are not cheap generic Chinese knock-offs. They are proper Australian-made pumps from a long-established manufacturer with deep roots in the local pool industry.
Reltech originally made the plastic wet-end parts for Hurlcon prior to Hurlcon becoming AstralPool. That history is one of the reasons the SS 100 is such a logical retrofit choice for older Astral and Hurlcon pump installations.
The SunSol SS Series uses the same wet-end technology as the PR Series, but with a more cost-effective motor. That makes it a good option where you want an Australian-made retrofit pump at a sharper price point, while still keeping the familiar wet-end design and plumbing compatibility.
If you are replacing an older AstralPool E230, E 230, Astral E-Series 1.0HP, or some related older Astral / Hurlcon pump models, the Reltech SunSol SS 100 is one of the main retrofit options in Australia.

Important Retrofit Notes
Retrofit does not always mean every old pump will be 100% identical in every measurement, cable position, or union arrangement. In this context it generally means this pump is commonly used to replace the same class and plumbing footprint of older pumps such as the E230 and related models, usually without major plumbing changes.
Online references show the AstralPool E230 is a 1.0HP small-to-medium pool pump, while the Reltech SunSol SS 100 sits in the same general replacement space and is commonly sold as a retrofit for older Astral / Hurlcon pumps. As always, check your existing pump label and plumbing before ordering.
That said, we still recommend checking:
- Union style and thread type
- Centreline height and available equipment space
- Pipe size at suction and discharge
- Electrical supply suitability
- Whether your old pump was a true 1.0HP unit
If you are unsure, compare your existing pump label and photos before ordering.

Who This Pump Suits
This pump suits pool owners wanting a quality Australian-made single-speed replacement for an older Astral / Hurlcon pump without dropping into a cheap unknown import. It is especially popular where people want a reliable, quieter, good-value pump for everyday filtration, solar heating, or heat pump circulation duties.
Please Check Before Ordering
Because older pumps were sold over many years and under multiple brand names, always check your existing pump label, horsepower, plumbing size, and overall footprint before purchase. Some older installations may have been modified over time.
If you are replacing an E230 / E 230 / E-Series 1.0HP style pump, this is one of the main retrofit options people look for.
In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
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 |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly 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 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 |
