The LEWA ecosmart hydraulically actuated diaphragm pump does not just have a smart price, but smart technology as well.
The unique pumping speed of the LEWA ecosmart diaphragm metering pump distinguishes it from other pumps. With an absolute suction pressure of up to 0.1 bar abs., it not only provides a wide array of safe installation options. The operating costs for the entire system can also be lower than with other pumps.
The ecosmart series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. In this standard, all requirements for a displacement pump in industrial settings are defined with respect to design, construction, performance and acceptance tests. We also adhere to additional, globally valid standards such as VDMA 24284, 24286‐10 and FDA guidelines.
For us, safety and reliability comes first: The pump is not subjected to damage, even after operating errors occur or in extreme operating states. We offer maximum protection for user and machine through built-in safety mechanisms - not only when excess primary pressure is present, but also when the discharge or suction line is closed.
Our patented sandwich diaphragm is not just extremely durable, it is also well-protected. There is a corresponding, correctly sized PTFE diaphragm in a safety sandwich design for each of the four LEWA ecosmart sizes.
Diaphragm pumps work without dynamic seals in the process fluid area. This forms a hermetically sealed working area. No emissions escape to the outside, and contamination of the fluid is impossible.
With the combination of various pump heads and gear units, the inexpensive LEWA ecosmart diaphragm metering pumps cover a wide performance spectrum. We provide you with an energy-efficient pump for any application desired. Save space and weight through multiple arrangement of the pumps and meter multiple fluids at the same time with various pump heads.
