BL 7917: ORP Controller and Pump

• Proportional dosing
• ±5 mV accuracy with unbeatable performance
• Isolated 4 to 20 mA recorder output

ORP controller and dosing pump in one compact unit.±5 mV accuracy with unbeatable performance. Isolated 4 to 20 mA recorder output. Proportional dosing slows the pump down when the measured ORP level approaches the set value which avoids over dosage of oxidizing or reducing agents. Alarm contact is activated whenever the ORP reading varies more than 200 mV from the set point. Auxiliary contacts allow the user to attach a mixer or priming pump that is activated only when the pump is dosing. PVDF, FPM/FKM and PTFE materials are used for all parts that come in contact with the liquids being pumped.

BL 7917D is supplied with discharge and suction valves, polyethylene tubing, 220/240V power cable and instructions. BL 7917U is supplied with discharge and suction valves, polyethylene tubing, 110/115V power cable and instructions.
