Description

Description

Widely used in plating, wastewater treatment, water treatment and swimming pools, the BL7916 provides convenient installation, ease of use and maximum reliability.

  • Easy Installation: Designed with mounting holes built into the base and front-facing controls and pump assemblies
  • Proportional Dosing: Slows the stroke rate as the measured value approaches the user selected point, avoiding overdosage
  • Rugged Construction: Rugged, fiber-reinforced polypropylene IP55 rated casing; parts with chemical contact made of PVDF, FPM/FKM and PTFE
  • Isolated Recorder Output: To enhance troubleshooting and the ability to record data while monitoring the application
  • Simple Pump Action: A positive displacement solenoid with few moving parts with no rotating parts, gears or cams to drastically reduce mechanical failures
  • Auxiliary Dosing Contacts: Allows the user to attach a mixer or priming pump that is activated only when the pump is dosing
