Aquamaster C20 Twin Pump Set (Nutrient A&B)

The C20 is a compact and dedicated dosing unit featuring two independent peristaltic pumps, designed specifically for accurate nutrient (EC) dosing. It is intended exclusively for nutrient delivery and does not support pH adjustment. Each pump delivers a consistent dosing rate of 1.5 ml per second, providing fast, precise, and reliable nutrient application.

Connection Options & Use Cases

The C20 offers flexible integration depending on system requirements:

• Two-nutrient systems The C20 can be connected directly to a compatible controller via the right UTP port. In this setup, the pumps are automatically assigned as Pump 1 and Pump 2 within the controller interface.
• Expansion module for the C30 When connected as an add-on to a C30 unit, the C20 is automatically detected, with its pumps assigned as Pump 4 and Pump 5 in the controller menu.

The unit features a UTP input port on the underside for connection to either a controller or a C30. Unlike the C30, the C20 does not include a UTP output, meaning it cannot be expanded further with additional dosing modules.

For physical integration, the C20 includes an integrated side rail, allowing it to be mechanically connected to other modules such as the C30 or C10. Each pump is also equipped with a manual priming button, enabling individual pump activation — ideal for priming lines or draining tubing during installation and maintenance.

System Capacity Note: A single controller supports a maximum of five EC dosing pumps (nutrients) and one pH dosing pump, allowing up to six pumps per system in total.
