H2Q catalogue | 25 SUBMERSIBLE PUMPS CONSTRUCTION SITE SUBMERSIBLE PUMPS H2Q KBZE INTELLIGENT SUBMERSIBLE PUMPS The H2Q KBZE pumps are intelligent submersible drainage pumps equipped with an electrode-based automatic control system. This integrated system allows the pumps to start and stop automatically without the need for external control panels, preventing dry running, optimizing energy efficiency, and extending the pump’s service life. The H2Q KBZE intelligent system provides: • Reverse phase protection ensuring correct impeller rotation • Protection against open phase conditions and impeller blockage • Automatic shutdown during overload or abnormal voltage, with restart after approx. 5 min • Automatic thermal shutdown and restart after cooling • Adjustable water level probe allowing precise automatic operation. The pump stops working within 60s after water level reaches below the probe. When the water level rises to reach the electric probe, pump starts operating again. APPLICATIONS • Civil engineering • Mines and quarries • Coal mines and slurry handling • Sewage treatment plants • General pumping applications Code Model Pump Packaging N.W. (kg) LxWxH (mm) G.W.
