Easy Installation

Designed with mounting holes built into a rugged base, BL7916 is simple to install. All of the controls and pump assemblies are conveniently located on the front of the unit.

Proportional Dosing

A proportional control slows down the stroke rate as the measured value approaches the user-selectable set points, avoiding overdosage of chemicals. This feature makes the pump’s dosing more accurate, saves chemicals and eliminates unnecessary and costly corrections to your process, especially with slow reacting chemicals.

Simple Pump Action

A positive displacement solenoid with few moving parts makes the BL7916 more reliable than motor-driven pumps since there is no rotating parts, gears or cams; drastically reducing any chance of mechanical failure.

Isolated Recorder Output

To enhance troubleshooting and the ability to record data while monitoring, simply attach a recording device to the instrument’s 4 to 20 mA output contacts, conveniently located on the front panel, to obtain a copy of the results on demand.

Auxiliary Dosing Contacts

Allows the user to attach a mixer or priming pump that is activated only when the pump is dosing.
