LEWA MAH, MBH, MLM Series Micro-Metering Pumps

LEWA MAH, MBH, and MLM Series Micro-Metering Pumps are designed for applications that require highly controlled metering of very small liquid quantities.

These precision metering pumps use a hydraulically actuated metal diaphragm with a solenoid actuator to support accurate micro-flow dosing in industrial and process environments.

Process Controls Corporation - LEWA MAH, MBH, MLM Series Micro-Metering Pumps

The series covers flow rates from 0.01 to 55 l/h and discharge pressures from 1 to 560 bar, depending on pump configuration and operating requirements.

The MAH, MBH, and MLM Series are used where small-volume chemical injection, additive metering, proportional dosing or controlled fluid adjustment are required. This pump series can be utilized in applications such as inline blending, natural gas odorization, additive supply, and adjustment of material values such as coloring, viscosity, or pH in larger process flows.

These micro-metering pumps are available in multiple variants, including options with or without explosion protection depending on the series and application environment. The MLM Series also includes an integrated pressure relief valve in the hydraulic section to help address potential overload conditions.

Process Controls Corporation can support customers in reviewing micro-metering pump requirements based on flow rate, pressure, process conditions, installation needs, and control requirements.
