The ecosmart pumps are also suitable for almost all fluids and are already being used in numerous industries. They offer the highest metering accuracy, safety and reliability and excellent efficiency, all packaged in a compact design. Flow rates of up to 300 l/h per pump head and a maximum flow rate of 80 bar are possible.

Unique suction capacity

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.

Highest metering accuracy

The flow rate of the ecosmart diaphragm metering pump can be set precisely by adjusting the rotation speed of the motor and through manual stroke adjustment. This allows you to meter various fluids for your processes to the precise defined quantities.

Absolutely safe startup

Starting up the metering pump is safe and easy: When the pump is not operating, a spring pulls the diaphragm into a safe position at all times. This allows us to guarantee maximum safety when starting up your system and optimum protection of the diaphragm.

Low maintenance costs and a long service life

The ecosmart series features a long service life for all components and particularly low maintenance and operating costs. If regular maintenance intervals are maintained, our diaphragm pumps can operate for 40 years or more in your production process.

API 675‐Standard

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.

Safety and reliability in extreme operating states

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.

Patented sandwich diaphragm

Our patented LEWA sandwich diaphragm is not only extremely durable, but also well-protected. The LEWA DPS diaphragm protection system and a diaphragm monitoring system allow us to ensure that the diaphragm does not tear during operation and that the pump fluid is not contaminated.

Hermetically sealed

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.

Integrated pressure relief valve

A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations in operation. This valve is individually adjustable and can therefore be adapted to different operating situations.
