Dosing and measuring equipment and spare parts
Automatic water treatment relies on two things working together: a measurement that tells you what the water is doing, and a pump that corrects it. Here you will find the exploded views for AstralPool dosing systems and controllers, so individual components can be ordered rather than replacing a complete unit. The range covers peristaltic and solenoid dosing pumps, volumetric pumps, measurement and control panels for pH, redox and free chlorine, and the wearing parts that keep them accurate.
Because these pages are built from exploded drawings, each component carries a position number. Working from the drawing for your own model is always more reliable than matching on appearance alone, as tubing bores, connector sizes and injection valve threads differ between pump families even where the housings look similar.
Which pumps and controllers are covered
The listing spans several generations of AstralPool dosing equipment, from simple single-parameter units to combined panels that regulate pH and disinfection from one enclosure.
- Class Combi pH/redox — combined dosing stations in 1 L/h, 2 L/h and 10 L/h versions at 5 bar, each with its own pump head and tubing parts.
- Controller 3 Plus and Controller 4 Plus — pH and chlorine control units, plus the Modbus and free chlorine variants for installations integrated into a wider control system.
- Redox Basic EV — compact redox control, including the black (negro) housing version.
- Mypool redox — small 1.6 L, 1.5 bar, 230 V dosing units for domestic pools.
- Optima and Maxi UP pumps — manual and controlled pumps for pH+, pH- and redox dosing, with Optima manual types supplied in different pressure and head configurations.
- Exactus volumetric and pH/RX pumps — including the VFT/MB versions, where the measuring chamber and valve set are the usual service items.
- Peristaltic pumps — where the tube itself is the consumable and is designed to be changed on schedule.
Parts that wear and need replacing
Dosing equipment handles acid, chlorine donors and flocculant, so almost everything in the liquid path is a consumable. Planning replacements is usually cheaper than reacting to a leak.
- Peristaltic tubing — flattens and hardens with use; a pump that runs but no longer primes is almost always a tube problem.
- Injection valves and non-return valves — scale and crystallised product block the duckbill or spring seat, causing back-pressure faults.
- Suction lances and foot filters — the strainer clogs, and the level sensor fails to signal an empty drum.
- Diaphragms, valve sets and O-rings — the core service items on solenoid and volumetric heads.
- pH and redox probes — have a limited working life; drifting readings that will not hold calibration point to the electrode rather than the controller.
- Flow cells, holders and BNC cabling — cracked cells and damp connectors produce erratic measurement.
- Keypads, membranes and electronic boards — available separately on many controller models.
How to identify the right component
Start from the model name on the rating plate or the front panel, then open the matching exploded view and note the position number of the part you need. For pumps, the stated flow rate and pressure, such as 2 L/h at 5 bar, forms part of the identification, because the same body may be fitted with different heads.
For tubing and seals, measure before ordering: internal and external diameter for hose and peristaltic tube, and internal diameter, external diameter and thickness for O-rings. Check the thread or push-fit size at the injection point as well. If a probe is being replaced, confirm the connector type and the cable length you need, and whether the holder already in the pipework will accept it.
Dosing & measuring at PoolParthub.com
Here we list exploded views and component parts for the AstralPool dosing and measuring range, including Class Combi, Controller 3 Plus and 4 Plus, Redox Basic EV, Mypool, Optima, Maxi UP, Exactus and peristaltic pumps. The aim is to let an installer or pool owner repair a working unit instead of discarding it.
The catalogue is organised by model and position number so that tubing, valves, probes, seals and electronic parts can be matched to the equipment already installed. Orders are shipped to customers throughout Europe.
