Series M Product Specification
Series 'M' mechanically actuated diaphragm metering pumps are offered in two models:
Model LI2 and LI4 pumps are the most economic offering. These models covers applications from 26 LPH to 246 LPH @ 10 bar (7 GPH to 65 GPH @ 150 psig).
Model L2 and L6 pumps feature the PULSAR drive end and an automatic micro-processor based stroke length actuator. Flow capacities greater than the LI models.
These pumps are suitable for applications from 10 LPH @ 21 bar (2.7 GPH @ 105 psig) to 599 LPH @ 5.2 bar (158 GPH @ 75 psig).
