LMI Series P Metering Pumps

LMI Series P Pumps for durability in OEM applications.

The LMI Milton Roy Series AA electromagnetic solenoid driven diaphragm pumps have manually adjustable stroke length control providing accurate pump output adjustment. The time tested electronics are totally encapsulated for protection against moisture and corrosive conditions, owing to the reliable, repeatable performances. NEMA 4X / IP65 enclosures ensure protection against corrosive environments. The priming valves have Fluorofilm® diaphragms and ramp style knobs for hands free priming.

P0 models offer manual stroke length and fixed stroke frequency.
P1 models offer manual stroke length and stroke frequency control.
P7 models offer manual stroke length and selectable manual stroke frequency control or external pacing control.
Adjustable stroke frequency and stroke length provide the flexibility of up to 500:1 turn down ratio.
Stroke frequency adjustable from 1 to 100 strokes per minute. (fixed for models P0).
Viscosities up to 400 centipoise standard, up to 40,000 cps (optional with HV coded liquid end).

LMI Series P Datasheet shows the LMI Series P pump configuration, specifications and options per model number.
LMI Series P Specification Sheet shows additional information on each LMI pump Series P model type and specifications on drives, wet end, and general pressure.
LMI Chemical Resistance Chart shows the pump liquid end material chemical compatibility.
LMI Electronic Metering Pump Instruction Manual gives a detailed instruction for usage and descriptions on various parts of the pump.
