The submersible pump BKB 750M is the central pressurization unit for your rainwater harvesting system. By connectable Floating extraction the cleanest water is pumped from the storage tank. The integrated circuit including automatic check valve controls the submersible pump volume flow and pressure dependent.

‍

For a pressure drop (opening the consumer), the submersible pump switches on automatically. Once the maximum pressure (consumer closed) is rebuilt and no current flows more volume, the submersible pump is switched off. In addition, the automatic switch includes a dry-run protection, which switches off the pump at a dry run and protects against damage. The already integrated vessel-tank reduces number of starts leaking from consumers and thus increases the life of the submersible pump.
