Oil & Gas
You can rely on 60 years of experience in the construction of pumps, packages, skids, and systems for onshore and offshore oil and gas production. Take a look at the information now!
In the oil and gas industry, in gas odorizing and in the energy industry, fluid components are often metered in extremely small amounts, proportionally to the variable reference value.
MAH, MBH and MLM micro-metering pumps from LEWA represent an efficient solution for exactly these types of applications: They have an extremely wide control range for maximum metering flexibility and can also still implement small flow rates. With four different solenoid power sizes, they cover an extensive field of application.
The small pump types of the series are also available with solenoids without Ex protection; these can work against higher pressure. The two control systems specifically developed for this program permit adaptation to a wide variety of different tasks.
LEWA micro-metering pumps are metering pumps with a hydraulically actuated metal diaphragm and solenoid actuator.
For us, safety and reliability comes first: The pump is not subjected to damage, even after operating errors occur or in extreme operating states. We offer maximum protection for user and machine through built-in safety mechanisms - not only when excess primary pressure is present, but also when the pressure or suction line is closed.
LEWA micro-metering pumps are not only leak-proof, but also absolutely odor-tight. This ensures that no contamination can occur.
The micro-metering pumps are suitable for many different fluids. Whether they are dangerous, toxic, abrasive, viscous, environmentally harmful or sensitive fluids, the user-specific configuration always gives you the correct diaphragm metering pump.
The metering pumps are equipped with sophisticated metal diaphragm technology, which enables discharge pressures up to 500 bar. At the same time, they still meter very precisely at an accuracy of ± 1%.
The pumps are dry-run safe. No sliding seals or packages are inserted. This guarantees the highest process safety.
The LEWA series M micro-metering pump is available in numerous performance and size variants. We are happy to assist you in selecting the suitable pump for your application.
With the various micro-metering pump variants MAH, MBH and MLM – available with or without explosion protection – we cover flow rates from 0.01 to 55 l/h and discharge pressures from 4 to 560 bar.
|Type||Without Ex protection||With Ex protection|
|Flow rate [l/h]||At max. pressure [bar]||Flow rate [l/hr]||At max. pressure [bar]|
Various sizes for any intended use: MAH, MBH and MLM differ significantly in their dimensions, MAH and MLM are each available in two different sizes.
|Type||L [mm]||B [mm]||H [mm]|
|MLM 15/40 -3||450||140||260|
|MLM 15/40 -20||450||180||260|
LEWA MAH, MBH, MLM micro-metering pumps can be found in numerous applications:
Proportional metering of fluids in variable main currents, e.g. inline blending, natural gas odorization, additive supply, regulation of physical material values to main currents or large volumes with a good mixture in higher-level control circuits, e.g. coloring, viscosity, pH values.
