LMI Microprocessor-Controlled Solenoid Diaphragm Metering Pumps

Robust processor-based control offers improved electromagnetics.

Easy-to-use push button controls with LCD user interface
Manual stroke length knob
Low level float switch connection
Lockable clear cover
NEMA 4X / IP65 enclosure

Choose from manual control, remote control, and digital remote control pump options.

Manual control models feature manual stroke length and frequency adjustment. Low level indication is possible via the remote input. LCD provides quick user feedback of pump status and theoretical pump flow.

Remote control models accept a pulse or 4 to 20 mA input control signal. Use the keypad to manually adjust the stroke length and frequency (when in local mode). Pump has a dual low-level float switch input and a 24 V output. LCD provides quick user feedback of pump status and theoretical pump flow.

Digital remote control models offer all the same features of the remote control pumps as well as remote on/off and remote internal/external inputs; plus, 4 to 20 mA, pulse, and alarm outputs. An upgraded LCD offers a graphical display of pump status and theoretical pump flow.
