Dosing Pumps are optimized as standalone devices. Therefore they are very compact and have a control panel. Standalone devices are the BlueShadow Pumps 40P and 80P as well as the AZURA P 2.1S and P 4.1S. The AZURA P2.1L and 6.1L are designed as system devices. So they don’t have an own display. Their footprint and design fits perfectly into our AZURA systems.
