AstralPool - Analogue Circuit 20 L/H for Optima Dosing Pump Type D 5 Bar - 36009R0012

AstralPool – Analogue Circuit 20 L/H for Optima Dosing Pump Type D 5 Bar

This is the genuine AstralPool replacement analogue circuit for the Optima Manual Dosing Pump Type D, rated at 20 L/H and 5 bar (parent pump SKU 57135). It is the internal electronic control board that governs the pump’s dosing frequency, allowing the flow rate to be set as a percentage via the front-panel potentiometer. Replacing a faulty circuit restores precise, reliable chemical dosing to your pool water treatment system.

How It Works

The analogue circuit directly controls the operating frequency of the Optima membrane dosing pump. Flow rate is adjusted by a potentiometer under the front panel, which modifies how often the pump strokes. The Optima analogue series also supports a double control scale, allowing the maximum dosing frequency to be divided by five — effectively giving two dosing ranges within a single pump model.

Compatibility

This circuit is designed exclusively for the AstralPool Optima Manual Dosing Pump Type D at 5 bar / 20 L/H (parent SKU 57135). It occupies position 2 in the official Fluidra exploded view diagram for that pump. Always verify your pump’s model number and exploded view position before ordering to ensure an exact fit.

Why Genuine Matters

As a certified genuine AstralPool spare part, this analogue circuit is manufactured to the same specification as the original component, ensuring accurate dosing performance and full compatibility with the Optima pump’s anti-acid casing and anti-humidity control interface. Using non-genuine electronics in a chemical dosing environment risks inaccurate flow rates and potential pump damage.
