Other documents used in the development of the CSS configuration are as follows: The usual appearance of them is to have the cause on the left hand side with the effect at the top with a 'X' matrix. Sometimes logic symbols are included which make the operator's engineering design requirements unambiguous. Whilst this is an excellent approach it is rather costly, thus it is infrequently used.

No matter if offshore in rough seas or in production in pharmaceutical cleanrooms — the ecoflow diaphragm metering pump has established itself worldwide in a range of different industries as a reliable and economical metering pump.

It features an exact metering rate and enormous durability in extreme operating conditions. Low life cycle costs and high energy efficiency complete the profile of a true all-around talent. Thanks to the tried-and-tested modular system, ecoflow diaphragm metering pumps can be configured with various pump heads and drives for almost all applications.

Here, we set technological and qualitative standards: Each ecoflow diaphragm metering pump is equipped with the patented DPS diaphragm protection system and produced in Germany.

Unique suction capacity The LEWA ecoflow diaphragm metering pump differs from other pumps due to its unique suction capacity. With an absolute suction pressure of up to 0. The operating costs for the entire system can also be lower than with other pumps.


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 a long service life of the diaphragm.

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

It includes all definitions for a diaphragm metering pump in industrial use in terms of its design, construction, performance and acceptance test. 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 pressure or suction line is closed.

Suitable for virtually all fluids The ecoflow series is suitable for almost all liquids thanks to its flexible design. Whether they are dangerous, toxic, abrasive, viscous, environmentally harmful or sensitive fluids, the user-specific configuration always gives you the correct diaphragm metering pump.

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.

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.

High energy efficiency LEWA diaphragm pumps achieve the highest efficiency of all pump technologies. Our ecoflow series also combines high efficiency with low energy consumption.The Instrumentation, Control, Safety Instrumented Systems and Fire and Gas Design Engineering pageis a fantastic resource for Instrument Engineers involved in Instrumentation, Control, Safety Instrumented Systems and Fire and Gas Design Engineering.

The first theoretical analysis of the behaviour of pipe bends when subject to a bending moment was made by Theodore Von Karman, who showed that when curved pipe is subjected to a bending moment in its own plane, the circular cross section undergoes changes and is .

Introduction to air-cooled heat exchangers. Water shortage and increasing costs, together with more recent concerns about water pollution and cooling tower plumes, have greatly reduced industry's use of water cooled heat exchangers.

The code that governs the design of piping systems for process plants is ASME B Process Piping. Piping engineers are responsible for interpreting the code using sound engineering judgment to ensure that the proposed design meets the code requirements.

KLM Technology Group Project Engineering Standard PIPING AND INSTRUMENTATION DIAGRAMS (P&ID) (PROJECT STANDARDS AND SPECIFICATIONS) Page 2 of Rev: A review of the current design approaches according to European (EN) and American (ASME B & B) standards is illustrated by using a typical refinery piping system as a case study.
