Fluidra - pH Dosing Pump Roller Holder Model 2 (pH 1.8–2.4) for Ei2 iQ PH 12

Fluidra – pH Dosing Pump Roller Holder Model 2 (pH 1.8–2.4) for Ei2 iQ PH 12

This is the genuine Fluidra replacement roller holder for the Model 2 peristaltic dosing pump head fitted to the Zodiac Ei2 iQ PH 12 salt chlorinator. It is the core rotating component inside the pump head that compresses the dosing tube, driving precise pH-correcting chemical into the pool water. Keeping this part in good condition is essential for accurate, uninterrupted pH dosing.

How It Works

Inside a peristaltic dosing pump, rollers mounted on the roller holder continuously squeeze the flexible dosing tube against the pump housing. This rolling compression action draws chemical from the reservoir and pushes it into the pool pipework in controlled doses. Wear or damage to the roller holder disrupts this action, leading to inaccurate dosing or pump failure — making timely replacement critical to maintaining correct water chemistry.

Compatibility

This roller holder is designed specifically for the Fluidra Zodiac Ei2 iQ PH 12 salt chlorinator’s integrated peristaltic pH dosing pump, Model 2 variant, covering the pH 1.8–2.4 operating range. Always verify your unit’s pump model before ordering, as the Ei2 iQ range includes multiple pump head variants that use different roller holder designs.

Why Genuine Matters

Using a genuine Fluidra spare part ensures dimensional accuracy and material compatibility with the original pump head housing and dosing tube. Off-brand alternatives may cause premature tube wear, chemical leaks, or inaccurate flow rates. A genuine replacement restores factory-standard performance and protects your Ei2 iQ PH 12 warranty.
