1. A solution for your special application

   From process analysis to global service

    

   • Listen, create, manufacture and service
     
     

   LEWA process experts can help solve your application requirements. Our first key is to listen intently to your objectives and goals, which may include converting a batch process to continuous, optimizing an existing system, or designing a new concept. Our process, mechanical, automation and design professionals simplify and
   optimize all aspects of the project, while creating a quality solution.
   
   
   

   

   _{From the first draft to a tailor-made solution}

    

    

   • Fluid evaluations
     
     

   Moreover the fluid evaluation offered by LEWA provides detailed information about whether and how the fluid can be metered. Thus recommendations can be given on the selection of the wetted materials, the pump design and also on the complete installation, which can save costs. All safety regulations e.g. for hazardous fluids are considered in these recommendations.

   • Lifetime services

   
   

   Our definition of customer benefit includes more than just technical features and high standards for quality. A critical core expertise of LEWA is the worldwide service and spare parts support. Through ongoing training of the entire personnel in the global after sales organization the customer can count on speedy and expert support in the event of a problem.

    

   Apart from the global assistance for packages and systems during assembly and commissioning, economical modernization or optimization concepts are also developed together with the customer (e.g. Register your pump, Health check).

    

   Service contracts individually tailored to the customer’s requirements and original spare parts increase the operational safety, reduce the operating costs and extend the service life of the plant.
   
   
   

2. Highest process safety

   • Individual pump configuration and state-of-the-art design

   
   One of LEWA’s strengths is the design of customer specific solutions. In cooperation with the customer skids, packages or complete process systems are developed. This not only includes the mechanical design, but also the control protocols.

    

   

    

   In addition to individual process parameters, the design is in line with the corresponding requirements of the guidelines in force, e.g. ATEX, DGRL (PED); VbF, WHG.

   • Piping calculations

   
   

   _{Evaluation of pulsation and pressure loss: evaluation of mass pressure
   and friction pressure, graphic illustration of the results}

    

   To assure proper function of the pump in the plant, the interaction of the reciprocating positive displacement pump and the pipelines connected to it, must be considered in the early stages of development.

    

   With our software “Pump Design” specially developed for LEWA pumps, we can check the installation for cavitation / overload and excessive metering, as well as resonance, taking the properties of the fluid into consideration. If required, optimizing measures for pipeline dimensioning, pulsation damping etc. are proposed.

    

   If requested, a full pulsation study can be provided.
   
   

    

   • Diaphragm Protection System and fail-safe M900 pumphead design

   
   

   _{M900 Diaphragm pump heads}
   
   

   LEWA provides the most advanced diaphragm metering pumps in the world with maximum security for both production and the environment, primarily through the unique DPS (Diaphragm Protection System)*.
   
   The DPS system assures safety, even under extreme operating conditions, like high suction pressure or closed suction line. The internal overpressure protection is assured by a integrated pressure limit valve.
   

   
   LEWA diaphragm pump heads are the safe and hermetically tight alternative for medium to high pressures. They present the economical solution for a variety of metering applications.

    

   Ecologically damaging, dangerous, sensitive or abrasive fluids today are metered with zero leakage diaphragm pumps only. Any diaphragm damage is displayed reliably. In spite of this the pump remains tight and operation can continue for a limited time.

   • Condition Monitoring System

   With LEWA CMS*, pump lifecycle costs are lowered by reducing machine downtime, accomplished by progressing from preventive to condition oriented maintenance and further reducing the probability of pump breakdown.

3. International engineering and project competencies

   From planning to delivery and long afterwards
   
   Customers worldwide benefit from LEWA’s experience and expertise which stretches back for over 50 years: If the customer manufactures in China for instance, the LEWA consultant is familiar with the relevant certificates and documentation in the Native language. If the EPC is based in the USA, the local branch can coordinate with engineers and operators onsite about process details. If the company is trading in Singapore, LEWA also has a branch there. The same applies to the Middle East, Africa, South America, Australia or every other distant part of the world.

    

   LEWA project management covers the world of planning, construction, building and installation; the capable commissioning as well as the briefing for customers’ staff members and later the regular maintenance and supply of spare parts even in remote areas of the world.

4. Highest reliability

   • Developed for continuous operation

    

   Over the decades, LEWA has gathered long-term in experience over a broad variety of diaphragm pumps sizes.
   
   

   Most of the applications in the chemical industry, refineries and offshore installations demand 8.000 hours or more per year.
   
   

   Generally LEWA’s products are designed and built for a service life of more than 25 years, even under extreme operating and environmental conditions. To quantify reliability figures of the normally rated life of critical components, meantime between unplanned failure data is collected. Based on continuous operation from year to year LEWA would expect a down time of about 3 days hence an availability of up to 99%.

    

   Expected component life in normal operation:
   
   

   • diaphragms 8.000 – 15.000 hours
   • pump valves 5.000 – 8.000 hours
   • hydraulic valves / plunger 20.000 – 30.000 hours
   • crankcase bearings 70.000 hours
   • motor bearings 50.000 hours
     
     
     

5. Low lifetime costs

   • Reduced energy consumption and low-wear design

    

   LEWA products are often used for applications that allow more environmentally friendly processes and a more energy-efficient production. This is due to the fact that LEWA pumps amongst others have the best possible pump efficiency rate.

    

   For example in CO₂ re-injection in fossil waste disposal sites up to 35% of the energy costs can be saved, if LEWA pumps are used instead of compressors. This saving is possible because LEWA pumps have an efficiency of > 80 %.

6. Compliance to international standards

   API, ASME, GOST-R, FDA, EHEDG, 3A, TÜV, etc.

    

   For decades, LEWA has closely cooperated with specialized external companies in this field. All applicable standards and regulations are considered. Of course, LEWA complies with all established national and international standards:

    

   • Certified according to DIN EN ISO 9001: 2000; GOST R
