Aquasalis variable-speed pumps and salt chlorinators

Aquasalis equipment covers two of the jobs that keep a pool clear: moving the water and disinfecting it. The VP series are variable-speed circulation pumps, the SC series are salt chlorinators that produce chlorine from dissolved salt in the water. Here you will find both ranges together, so a filtration circuit and its sanitation can be specified in one go, or a single unit replaced when the pool is already built.

The line-up is built around a small number of clearly stepped models, which makes matching an existing installation straightforward. The VP pumps run from 1 HP up to 3 HP, and the SC chlorinators from 6 g/h up to 25 g/h of chlorine output, each offered with a choice of electrode service life.

• VP 7 and VP 11 – 1 HP and 1.5 HP, suited to smaller domestic pools and modest filter areas.
• VP 13 and VP 18 – 1.75 HP and 2.4 HP, the usual choice where there is more pipe run, a longer suction line or additional features drawing flow.
• VP 22 – 3 HP, for larger volumes and circuits with higher total head.
• SC 6 to SC 12 – 6, 8, 10 and 12 g/h, for small to mid-sized private pools.
• SC 16 to SC 25 – 16, 20 and 25 g/h, for larger volumes, warmer climates or pools under heavy use.
• Electrode options – each SC output is listed with a 7,000 hour or a 10,000 hour electrode.

Choosing a VP variable-speed pump

A variable-speed pump is chosen on flow and head, not on horsepower alone. Work out the flow your filter needs to turn the pool volume over within your usual filtration hours, check that figure against the filter’s recommended flow rate, then add the resistance of the pipework, skimmers, valves and any heater or UV unit. The point of running variable speed is that the pump can then sit at a low, quiet speed for everyday circulation and step up only for backwashing, vacuuming or a water feature.

When replacing an older single-speed pump, note the existing union sizes and the centre height of the suction and discharge ports before ordering, and check the space available in the plant room — pump bodies and motor lengths differ between models. Keep the old strainer basket dimensions to hand as well, as the basket and lid seal are the parts most often reordered afterwards.

Sizing an SC salt chlorinator

Chlorinator output is quoted in grams of chlorine per hour. The unit has to be able to cover the pool’s daily chlorine demand within the hours the filtration pump actually runs, so volume, water temperature, sunlight and bather load all matter. A pool in a hot, exposed garden consumes far more than the same volume under cover. Common practice is to choose one step up from the bare minimum rather than running a small cell flat out, because an under-sized unit has no reserve during a heatwave and its electrode is worked harder.

The cell is plumbed into the return line after the filter and any heater, and the control unit needs the pump to be running before it will produce chlorine. Salt level, pH and stabiliser all need to stay in range for the chlorine produced to be effective — a chlorinator replaces the task of dosing, not the task of testing.

Electrode life and replacement

The electrode is a consumable. It is the part that carries the current through the salt water, and the hour ratings in the product names — 7,000 or 10,000 hours — describe how long that plate pack is rated to work before output falls away. Those hours accumulate only while the unit is actually generating, so a pool run for a long season reaches the figure sooner than one covered for half the year.

Scale build-up on the plates is the usual cause of early loss of output, and it tracks back to high pH or hard water rather than to the cell itself. When ordering a replacement, match the model and the output in g/h exactly, and check the cell housing and union connections, since a cell from a different output step will not necessarily drop into the same body.

Here we list the VP variable-speed pumps from 1 HP to 3 HP alongside the SC chlorinators from 6 g/h to 25 g/h, each in both electrode versions. Having the full ladder of outputs on one page makes it easy to confirm which unit you have before ordering, or to move up a size if your pool has proved to need more capacity than the original specification allowed.

Both ranges serve pool owners and installers across Europe. If the label on your control unit or motor has faded, the model and output printed in these listings is usually enough to identify what is fitted, so the correct replacement or upgrade can be chosen with confidence.
