GHL Doser 2.1 Slave, 4 pumps precision dosing pumps

The GHL Doser 2.1 Slave requires control via a ProfiLux Controller or a GHL Doser 2.1 Stand Alone (which includes integrated control electronics). The 24V stepper motors provide accurate dosing even at very small flow rates (0.1 ml). You can connect it through WiFi, LAN, or USB.

This system can be expanded to accommodate a total of 16 pumps:

Stand Alone + 3 Slave Doser
ProfiLux Controller + 4 Slave Doser

The ProfiLux Aquatic Bus ensures reliable and interference-free data transfer, even at distances of up to 100 m (300 ft.).

The Doser 2.1 pumps are largely maintenance-free. For optimal performance, we recommend periodically cleaning and removing dust and other impurities from the inside of the pumps. It is important that the pumps are never lubricated in any way!

Tubes, pumps, and motors are wear parts, and their lifespan depends on usage frequency, flow quantity, and environmental conditions. If you encounter malfunctions (such as insufficient flow, losing prime, leaks, or increased operational noise) or mechanical damages, the wear parts will need to be replaced. Thanks to the maintenance-friendly design, all wear parts can be easily replaced, and they are available as accessories.
