LMI, AD811-910AM, Metering Pump 0.21 GPH, Pulse/Analog Input w/ Dual Manual Control, O-Ring PTFE/Polyprel, Acrylic/PVC, Metric Connection, AutoPrime Head, 110-120V US Plug
The AD8 series metering pump has a liquid crystal display to indicate pump stroke speed and theoretical flow rate. Applicable for specific chemical pumping application. Control and adjustment for stroke frequency shall be by means of a tactile keypad. Adjustment for stroke length shall be by means of a readily accessible dial knob. A pulse indicator light shall flash green between strokes when pumping. The pump shall be equipped with an on/off button and a low level float switch Input. When the low level sensor registers empty, the low level indicator light shall turn red and the pump shall turn off when it registers an empty level.
Pulse/Analog Input w/ Dual Manual Control: Pulse or 4-20 mA signal input controls frequency, LCD display, manual stroke length control, frequency manually adjustable when in local control, pulse multiply/divide functions, 24 V output for remote device. Includes dual low level float switch input. Display configurable to indicate theoretical pump flow.
AutoPrime™ liquid ends have 3 check valves: suction on the bottom; discharge on the front; auto prime bleed on the top. By design, a repeatable portion of the process fluid continuously bleeds through the top check valve to be returned to the chemical supply. The result is the assurance that any gas in the head is automatically relieved thus eliminating air-binding. Depending on application, output may be reduced up to 50%.
