Why LEWA ecosmart® is the Smart Choice in Metering
Exceptional Suction Capability
The LEWA ecosmart diaphragm metering pump stands out for its exceptional pumping speed, setting it apart from other pumps. With an absolute suction pressure reaching up to 1.5 psi abs., it offers a versatile range of safe installation possibilities. Additionally, it helps reduce overall operating costs for the entire system, making it more cost-effective compared to other pump options.
Superior Metering Precision
The ecosmart diaphragm metering pump offers precise flow rate control through motor speed adjustment and manual stroke settings. This ensures accurate metering of different fluids for your processes, allowing you to achieve the exact specified quantities.
Completely Secure Startup
Starting the metering pump is both safe and straightforward: when the pump is inactive, a spring mechanism automatically positions the diaphragm securely. This design ensures maximum safety during system startup and provides optimal protection for the diaphragm.
Minimal Maintenance Expenses and Extended Service Life
The ecosmart series is designed for durability, offering a long service life for all components along with notably low maintenance and operating costs. With proper adherence to maintenance schedules, our diaphragm pumps can reliably function for over 40 years in your production process.
API 675‐Standard
The ecosmart series meets the globally recognized quality standard of the American Petroleum Institute (API) 675, which outlines all design, construction, performance, and acceptance test requirements for displacement pumps in industrial applications. Additionally, we comply with other international standards, including VDMA 24284, 24286‐10, and FDA guidelines.
Dependable Safety and Reliability under Extreme Operating Conditions
For us, safety and reliability are top priorities. The pump remains protected even during operational errors or under extreme conditions. Our built-in safety mechanisms provide maximum protection for both the user and the machine, ensuring safety not just in cases of excess primary pressure but also when the discharge or suction line is closed.

Innovative, Patented Sandwich Diaphragm Design
Our patented LEWA sandwich diaphragm is engineered for exceptional durability and comprehensive protection. With the LEWA DPS (diaphragm protection system) and an integrated diaphragm monitoring system, we guarantee reliable operation without diaphragm rupture and prevent any contamination of the pump fluid.

Completely Leak-Proof
Diaphragm pumps operate without dynamic seals in the process fluid zone, creating a hermetically sealed working environment. This ensures zero emissions to the outside and eliminates the risk of fluid contamination.

Built-In Pressure Relief Valve
The diaphragm pump's hydraulic section includes an integrated pressure relief valve that prevents potential overload during operation. This adjustable valve can be tailored to various operating conditions, ensuring optimal performance and safety.
