In laboratories, test centers and other testing environments, small amounts of liquid media often have to be metered. Great value is placed on operational reliability and a broad spectrum of use in these environments. The metered flows have to be reproducible and controllable with high precision. The fluid has to be protected from any impurities.
The LEWA FC micro-metering pump completely satisfies the requirements for a laboratory pump. It is highly efficient and meters at an accuracy of ± 1%. Multiple pump heads and drives can also be combined as desired to form multiplex pumps. This allows high flow rates or metering of multiple different fluids in a process sequence.
So that it can be used in a wide variety of application areas and fulfill the specific requirements of our customers, it is available in two different designs: as a diaphragm pump or packed plunger metering pump.
Highest metering accuracy
The flow rate can be configured with absolute precision. The micro-metering pump works with an accuracy of ± 1%. This allows you to meter fluids in a process in precisely defined quantities. LEWA pumps feature this enormous precision.
Control and monitoring electronics
We analyze the requirements that develop from your use and supply the suitable micro-metering pump including specifically adjusted control and monitoring electronics. This allows you to achieve maximum efficiency when operating your systems.
Accurately operating drive unit
Absolute precision is our standard: LEWA micro-metering pumps have accurately operating drive units with an electric drive and a plunger spring return that is friction-locking and absolutely free of play. Thus, they are particularly well suited for laboratory applications in which precise metering is required.
Leak-proof and odor tight
LEWA micro-metering pumps are not only leak-proof, but also absolutely odor-tight.
All moving parts are continuously lubricated with oil. The pump is protected from weather and splash water.
Integrated pressure relief valve
A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations in operation. This valve is individually adjustable and can therefore be adapted to different operating situations.
The cam and spring drive has advantageous drive kinematics for the smallest metered flows.
Superior metal diaphragm technology
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%.
Wide adjustment range
The LEWA micro-metering pumps can be regulated in a wide adjustment range with consistently high efficiency and rigid compression curve.
The micro-metering pump is absolutely noiseless in operation, making it ideal for laboratory environments.
Dry-run safe and maintenance-friendly
The pumps are dry-run safe and maintenance friendly. No sliding seals or packages are inserted. This guarantees the highest process safety.
Ideal for supercritical and expensive fluids
FC micro-metering pumps are suitable for handling supercritical or expensive fluids due to precise and safe metering.
Single drive units with vertically installed motor are space-saving. Alternatively, multiple drive units with identical or different output can be combined for pulsation reduction or recipe metering.
Minimization of pulsation
Multiple pumps designed for the minimization of pulsation can avoid the use of pulsation dampers. Ideal for perishable or slightly contaminated fluids (CIP/SIP capable).
We supply pumps, equipment and systems on request in explosion-proof design for operation up to EX zone 1 . Thus, we guarantee maximum security.
Special micro filters
On demand, we equip your pump with special micro filters for dealing with high-purity fluids. This is especially recommended for applications in the pharmaceutical and food industry.
Special design materials
If the process demands it, wetted parts such as pumps heads and valves will be made of special materials such as stainless steel 316/316L (1.4401/1.4404), Hastelloy or Duplex steel and PVC.
Heating and cooling jackets
With heating and cooling jackets, our pumps are suitable for almost any temperature and can convey fluids at low temperatures or extreme heat.
Electrical stroke adjustment
Adjust the stroke length of your pump exactly to the specific metering task: LEWA pumps can be set fully automated by an electric stroke adjustment with integrated regulator.
LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.
Complete control/regulation program
Our pumps and systems come with a complete control/regulation program. Moreover, the use of programmable logic controllers (PLC) is possible.

LEWA has been your expert in pumps and packages since the 1950s. With us, you get everything from a single source: Our custom-built packages are used all around the world for offshore crude oil and natural gas production. From China to the United Arab Emirates, strong partners rely on our expertise for crude oil exploration applications.More Details
Natural gas, oxygen, and nitrogen are odorless but potentially dangerous. This is why these gases are "odorized" with as strong a smelling substance as possible. For more than 40 years, LEWA has been developing systems for the odorization of gases such as natural gases, biogases, and liquefied gases. This process is enormously important, so the odorizing system has to operate precisely and reliably.More Details
Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!More Details
