SICCE engineer their skimmer pumps SK & PSK from the ground up to run with maximum efficiency, low heat and reliability to produce pumps that are beyond compare. Every component of the entire pump, not just the impeller, is designed specifically for protein skimmer applications. This is what SICCE engineers call “AIR QUALITY”! Because the pumps are designed specifically for skimmer use, they offer the most efficient air mix ratio. The hydraulic and the mix of water to air flow is optimized for the intake and the pre-chamber design. PSK SDC PSK SDC pumps are the latest generation of pumps for skimmer applications and incorporate integrated intelligence systems for pumps installation in advanced systems. Specifically dedicated programming, control, excellent performance, energy efficiency, the possibility to use both in-line and submerged and low operating temperatures make this new range of pumps unique for their peculiarities. PSK SDC can be controlled with an easy-to-use controller or with your smartphone by free download of the new APP CONTRALL which makes these pumps programmable and controllable wherever Internet access is available. CONTRALL includes an alert system that keeps the end user updated in real time on the status of the pump.
