Pool Pump Prices: What Decides the Cost, and How to Choose
The pump draws water from the skimmers and main drain, pushes it through the filter and returns it to the pool. What you pay for it is decided by a handful of technical choices, and the right price is the price of the right size: a pump that is too big costs more twice — once when you buy it and again on every electricity bill. Each Waterstar pump's current price is shown on its product page; this guide quotes no figures.
What decides the price of a pool pump
- Motor power. 1, 1.5, 2 or 3 HP (0.75 to 2.2 kW). The power should follow the pool, not the other way round.
- Supply. The 1, 1.5 and 2 HP models are single-phase 220–240 V; the 3 HP models need a three-phase 220/380 V supply, with the protection and starter that go with it.
- Range. SuperStar, with 2″ inlet and outlet for larger pipework, or the compact HyperFlow with a 1.5″ inlet for tight plant rooms.
- Correct sizing. Oversizing raises the purchase price and the running cost, and can push the flow above the filter's rated flow, which spoils filtration.
- Running cost. Motor power and daily running hours decide the electricity bill for as long as the pump runs — part of the real cost of any pump.
- The rest of the circuit. The filter, valves and electrical protection are sized together with the pump, so compare complete systems, not bare pumps.
- Spare parts. Every component of a Waterstar pump is available as a spare part. A factory-new pump with known spares is a better long-term buy than a rebuilt second-hand motor of unknown history.
Waterstar pump ranges
| Range | Connections | Overall size (L × W × H) | Power |
|---|---|---|---|
| SuperStar | 2″ inlet and outlet | 600 × 375.5 × 390 mm (3 HP: 608 mm long) | 1, 1.5 and 2 HP single-phase; 3 HP three-phase |
| HyperFlow | 1.5″ inlet | 597 × 254 × 265 mm | 1, 1.5 and 2 HP single-phase; 3 HP three-phase |
All models run at 2800–2840 rpm with Class F insulation and IP55 protection, and carry a 1-year warranty. Single-phase models run on 220–240 V; the 3 HP models need a three-phase 220/380 V supply. SuperStar suits larger 2″ pipework; HyperFlow is the compact choice for tight plant rooms.
Which power does your pool need?
Start from the pool's circulation flow: the water volume divided by the turnover time, usually 8 hours (see the sand filter guide). Then read the performance curve published on each pump's product page at the head of your installation — pipe lengths and diameters, fittings, the filter and any heating or water features all add head — and make sure the filter's rated flow is not lower than the pump's flow. For example, our Villa Filtration Set for pools up to 150 m³ pairs a 1.5 HP SuperStar with the T900-36 filter.
Send us the pool dimensions and the plant-room layout and our technical team will specify the model from the curve.
A bigger pump is not a better pump: it costs more to run, raises the pressure across the filter and can push the flow above the filter's rated flow, which spoils filtration.
Spare parts for every model
Every component of a Waterstar pump is available as a spare part. One mechanical seal (SP-SEA-001) fits all eight SuperStar and HyperFlow models, and each motor rating is shared by both ranges, so parts are quick to find.
How to get a like-for-like quotation
Send us the pool volume, the distance and height difference between the pump and the pool, the filter you plan to use and the electrical supply available on site. We propose the pump and filter as one set, so every offer you compare covers the same duty. For projects and larger orders, request a quotation.
