The LEWA ecosmart: Smart Pricing, Smart Technology.

High suction capability of LEWA process pumps

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.

Safe metering of critical fluids with LEWA pumpheads

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.

LEWA pumps are manufactured according to API standards

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.

Hermetically tight, leakfree diaphragm pumps

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.

Options

Multiplex capability

Single drive units with vertically installed motor are space-saving. Alternatively, multiple drive units with identical or different output can be combined for pulsation reduction or recipe metering.

Customized valves

LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.

Diverse connection geometries

Our pumps are equipped with all common connection geometries such as DIN standard, BASF's high-pressure standard, American ANSI, JIS, or your individual requirements. Customized configurations are possible.

Special design materials

If the process demands it, wetted parts such as pumps heads and valves will be made of special materials such as stainless steel 1.4404 (316L), Hastelloy or Duplex steel and PVC.

Integration into process control systems

The signal acquisition of process control systems is achieved analogously or digitally. Flow rate is adjusted via electric or pneumatic stroke adjustment, alternatively by motor drive (FU).

Complete documentation

In the process of documentation, we consider your requirements and provide inspection records, print samples, diagrams of output characteristics and registration papers on request.

Integrated pressure relief valve

An integrated pressure relief valve prevents potential overload situations. The valve is individually adjustable and can be adapted to different operating situations.

Flow meters

A pump is only as good as its control and regulation system. That's why we provide precise flow meters in different variations for accurate control.

Painting according to customer's requirements

You want your pump or system to be compliant with your corporate branding guidelines? No problem for us: we paint pumps, skids and systems in the colors you prefer.
