ProGenius Chlorinator (DPG14 / DPG23, Last Sold 2019/21) exploded view & spare parts

Davey ProGenius Chlorinator (DPG14 / DPG23) exploded view & spare parts

This page covers the genuine Davey ProGenius salt water chlorinator in both factory configurations: the DPG14 en de DPG23. The DPG14 is rated for pools up to 70 m³, while the DPG23 handles pools up to 115 m³. Both models share the same overall architecture — a wall-mounted power supply housing the electronics, paired with a plumbed in-line electrolytic cell — and the exploded-view diagram on this page covers all nine numbered positions across both variants. Using the diagram alongside the parts list below, you should be able to identify the exact part you need within a few minutes.

Hoe u het genummerde schema kunt gebruiken om uw onderdeel te vinden

Every numbered call-out on the diagram corresponds directly to a row in the parts list table below. Start by locating the area of the unit that concerns you — for example, the power supply enclosure, the plumbing connections, or the in-line cell — then find the position number printed next to that component in the diagram. Take that number to the parts list, where you will find the matching description and SKU ready to add to your basket. Be aware that several position numbers appear twice in the list, once for the DPG14 and once for the DPG23: positions 1, 2, 3, 4, 7, and 9 all have model-specific variants, so always confirm which factory reference (DPG14 or DPG23) applies to your unit before ordering. The quickest way to confirm your model is to check the label on the power supply enclosure, which will state either DPG14 or DPG23. Positions 5, 6, and 8 — the Timer, the Cell Cord Assembly, and the Flow Switch — are shared across both models, so there is only one SKU for each of those. If you are unsure whether a part is the shared or the model-specific variant, the description column in the parts list makes this explicit.

Main replaceable assemblies on the Davey ProGenius

The ProGenius is organised into two principal sections: the power supply enclosure and the plumbed cell assembly. Position 1 is the Power Supply itself (SKU DPG14PS or DPG23PS), the weatherproof wall-mounted unit that houses all the low-voltage electronics. The power supply should not be located within 3 metres of the pool water and must be hardwired into a suitable weatherproof outlet in accordance with local standards. Inside the enclosure, position 2 is the Transformer (SKU 402771 for DPG14, 402772 for DPG23) and position 3 is the PCB (SKU M112014 for DPG14, M112023 for DPG23), the main control board responsible for regulating chlorine output. Position 4 is the Motor Protector (SKU 402677 or 402678), which safeguards the circulation pump circuit. Position 5, the Timer (SKU 14275), enables the chlorinator to run in step with the filter circulation pump. Position 6 is the Cell Cord Assembly (SKU M2678-10), the cable that carries power from the enclosure out to the in-line cell. In the plumbing section, position 7 is the Barrel Union Assembly — the mechanical connection between the pipework and the cell body — and position 8 is the Flow Switch (SKU 15712SP). The ProGenius is supplied with a paddle-type flow switch, which is installed directly on the cell. Finally, position 9 is the Replacement Cell (SKU DILC14REP or DILC23REP), a reverse-polarity in-line cell that benefits from regular monitoring to keep the chlorinator in the best possible condition.

Choosing between variants and pack sizes

The most important variant decision on this diagram is choosing the correct model-specific part for positions 1–4, 7, and 9. For position 7, the Barrel Union Assembly, the DPG14 uses 50 mm pipework connections while the DPG23 uses 63 mm connections — ordering the wrong size will result in a union that simply will not fit the pipe. The SKUs reflect this directly: 33204SP is the 50 mm assembly for the DPG14, and 48722B-1SP is the 63 mm assembly for the DPG23. For the electrolytic cells at position 9, the DPG14 and DPG23 cells are not interchangeable, as each is matched to the output capacity of its respective power supply and transformer. When replacing PCBs or transformers at positions 2 and 3, the same rule applies: the suffix on the SKU (14 or 23) always indicates the intended model. If your unit’s label is damaged or missing, cross-reference the pipe diameter at the barrel union to determine whether you have a DPG14 or a DPG23 before placing your order.
