Diaphragm metering pumps & process diaphragm pumps
for the energy and environmental sectors
LEWA pumps allow safe, environment-friendly production
Many applications confront our customers with critical, hence poisonous resp. toxic, carcinogenic or explosive fluids in the production but also already in pilot plants.
To mention just some of these fluids: ammonia, methanol, hydrosulphide, butanediol, liquid gases such as isobutane, pentane as well as CO2, but a variety additives and chemical mixtures also.
LEWA metering pumps as well as process diaphragm pumps are especially suitable for highest environmental demands, they are predestined for metering, conveying of e.g. toxic, inflammable, non-lubricating, solid particles containing or sterile fluids.
LEWA process diaphragms are used for the re-injection of CO2 into the ground as well as for the production of biofuels of the latest generation.
Due to their extremely safe design LEWA diaphragm pumps
are predestined for the following among others:
- for the wet oxidation of critical process waste water
- for the separation of sulphur from exhaust gas in power plants or for the ammiona waste water separation
- for the production of extrusion solutions of foaming agents metering
- for applications in the construction chemistry / spraying in the spray tower
- for the emission-free additive injection into natural gas pipelines with LEWA ecosave pumps
- in the field of carbon capture and storage (CCS) with LEWA process diaphragm pumps
for CO2 and H2S re-injection
Energy efficiency is of great importance.
The double energy requirement of e.g. centrifugal pumps correspondingly is considered negative with a more than 20% portion of the overall costs. Additionally LEWA pumps assure much lower life cycle costs due to considerable lower maintenance costs.
The LEWA Process Pump Technology offers the best efficiency over the complete metering range. Evidence for this are numerous customer projects for which LEWA has supplied diaphragm pumps with double the efficiency over the complete performance range compared to multistage centrifugal pumps.
Successful energy saving with LEWA pumps and systems - just some examples:
- for the production of bio-fuels of the second and also third generation.
- for after treatment of exhaust gases in power plants
- in odourizing processes LEWA odourizing units are used for the injection of additives into e.g. the biogas net. On request LEWA supplies small or big, customized odourizing units.
- for optimization of the heat balance in fabric softener production by means of heat exchangers LEWA supplies metering systems for re-cooling of the final product with the process water required for the final mixing procedure.
- LEWA also supplies packages with independent power supply such as solar-powered packages that are operated in extreme environments e.g. in Algeria, Columbia, Oman etc.
- for the processing of super-clean silicium in the solar cell production a leakage-free, process-safe metering- resp. process pump technology is required, LEWA here supplies the appropriate technology with the usual high product availability.
