Affordable even at higher flow rates: New pump sizes of the Ecosmart diaphragm metering pump from LEWA

Combine low purchase cost with high performance

In many applications in the oil and gas industry, the chemical industry or even the food industry, pumps that work reliably and provide high performance are needed. At the same time, they must have convincingly low investment costs. With the Ecosmart diaphragm metering pump, the German LEWA GmbH has provided a cost-attractive and safe model that can handle flow rates of up to 300 l/h for many years. For use in applications with higher flow rates, the pump expert from Leonberg, Germany, is now expanding its product range with two new sizes. In addition to the LCA version, the Ecosmart will also be available in the more powerful LCC and LCD versions in the future. While the LCC model can meter up to 1,000 l/h, LEWA designed the LCD for a flow rate of up to 2,000 l/h. The maximum permissible operating pressure for both models is 50 bar and 600 lbs respectively. The stringent use of similar components within the Ecosmart product family keeps production costs and therefore the final price low. At the same time, a high level of safety can be guaranteed by focusing on all essential design features such as the pressure relief valve or the proven sandwich diaphragm with continuous monitoring. The LCC variant is expected to be available at the end of 2021 and the LCD model in mid-2022.

In addition to the proven diaphragm metering pumps of the Ecoflow series, LEWA has offered the less expensive Ecosmart pump for several years. This is mainly due to the fact that although a reliable pump unit is required in numerous processes, at the same time relatively low discharge pressures in the lower two-digit range require less complex pump technology. With the Ecosmart LCA in the single pump version, however, only a flow rate of up to 300 l/h was previously possible. In order to be able to offer the Ecosmart for applications with higher flow rates, the engineers at LEWA began developing two additional, larger pump variants in 2019. The aim was to scale up the Ecosmart to larger applications with the proven safety level and high quality LEWA components without significantly increasing the low investment cost typical for this pump series. This was to be achieved by a consistent modular principle within the pump series, as well as a strict focus on the essential functions and features. The specifications also demanded the usual LEWA suitability for unrestricted continuous operation over many years. Options for integrating the pumps into automated systems via analog control signals or bus systems are also a matter of course.
