Many metering tasks take place in the low-pressure range. In principle, high-pressure pumps such as the LEWA ecoflow can also be used here, though it is usually not efficient to do so.
Another important reason to use mechanically actuated metering pumps is that they protect the pumping fluid from contamination because no hydraulic oil is used in the pump. Many customers prefer mechanically actuated diaphragm pumps, especially for pharmaceutical applications and fluids that react with hydraulic oil.
For this reason, LEWA offers the ecodos series as an efficient, safe solution for pumping fluid in the low-pressure range.
The LEWA ecodos is a mechanically actuated diaphragm metering pump with a monitored, 4-layer sandwich diaphragm for low pressures, which has numerous advantages over comparable pumps.
Simply integrate the LEWA ecodos into the existing production system: Control the output on the motor side using a frequency converter or with an automatic stroke adjustment. We are happy to advise you to ensure that your pumps run at maximum efficiency.
The ecodos metering diaphragm pump is mechanically driven (not hydraulically driven). This means that the pumping fluid will not get contaminated due to hydraulic oil or environmental influences.
Even if a diaphragm is damaged, continued operation is possible. Therefore, you have sufficient response time for maintenance purposes. This results in a high level of production reliability.
The LEWA ecodos diaphragm metering pump is available in various sizes, depending on the application. This pump implements flow rates of 16 to 1460 l/h.
