Aqua Master, C20 Pump Unit 2x, Peristaltic Dosing Pump.

The C20 is a compact dosing unit with two independent peristaltic pumps, specifically designed for the accurate dosing of nutrients. The C20 is only suitable for nutrient (EC) dosing and is not intended for pH adjustment.

Each pump delivers a standard dosing rate of 1.5 ml per second, ensuring fast and reliable nutrient delivery.

The C20 offers flexible usage options:

• In systems using two nutrients, the C20 can be connected directly to the controller via the right UTP port. In this configuration, the pumps will appear as Pump 1 and Pump 2 in the controller menu.
• When used in combination with a C30, the C20 can be connected as an extension. In this case, the C20 pumps will automatically be recognized as Pump 4 and Pump 5 in the controller menu.

The C20 is equipped with a UTP input on the bottom side for connection to either the controller or a C30. Unlike the C30, the C20 does not have a UTP output and therefore cannot be expanded further with additional pump units.

Mechanical connection to other modules, such as the C30 or C10, is possible via the integrated side rail. Each pump also features a manual priming button, allowing the pumps to be activated individually — ideal for priming or emptying the tubing during setup or maintenance.

Note: A maximum of 5 EC pumps (for nutrients) and 1 pH pump can be connected to a single controller, totaling 6 pumps per system.
