Lewa expands product range with new sizes

German pump manufacturer Lewa has added to its product range with two new pump sizes in its Ecosmart diaphragm metering pump range for use in applications with higher flow rates for use in the chemical industry and industrial wastewater treatment.

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 has designed the LCD for a flow rate of up to 2,000 l/h.

The use of similar components within the Ecosmart product family keeps production costs 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.

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 while retaining the safety levels and high quality Lewa components without significantly increasing investment costs.

Among the changes were larger plunger diameters which were selected for the smaller LCC variant, so that up to 1,000 l per hour can be conveyed instead of 300 l per hour. In the case of the more powerful LCD version, engineers decided to extend the stroke length so that a maximum flow rate of 2,000 l per hour could be achieved. Both pump types can work against a maximum operating pressure of 50 bar.

After successful completion of all tests and final adjustments, the Ecosmart version LCC is now on the market, the LCD model will follow in mid-2022.
