Boiler feed water The so called „Boiler feed water“ is stored in a feed water tank and continuously feeded to the boiler of a steam generator. A big quantity of feed water is needed for example in steam power plants. The boiler generates steam, which is used for heating, for chemical processes or for driving a steam turbine respectively a steam engine. The feed water is purified in a way, that all harmfull components for the boiler are removed or neutralized. Leakages and evaporation loss are compensated by additional water which is purified in the same way than boiler feed water. Very often, valuable well and potable water resources are used for the generation of process water. Environmental regulations restrict this usage of well and potable water continuously and increase the costs for this resources steadily. The conditioning of stream water to boiler feed water helps saving potable water and means cost advantages. The process of conditioning is based on ultra filtration with down

"In phosphating, a phosphorus-containing crystal coating is applied to steel parts and galvanised steel parts by a chemical surface process. There are various phosphate processes, e.g., zinc phosphate, zinc calcium phosphate, iron phosphate. The coating thickness is adjustable for special customer requirements. Beim Phosphatieren steht die Verformbarkeit und die Bildung eines Haftgrundes im Vordergrund. During phosphating processes, the formability and the formation of an adhesive primer is of primary importance. The coating weight is usually in the range of 1 to 15g/m². Phosphatisations are especially resistant to lubricants such as oils or greases, and therefore well-suited to many technical applications. . Phosphate coatings are usually further coated. This involves: Oiling, soaping, lubricant coating, vulcanising and painting."

Structure of germanBelt® steel cord conveyor belts Steel cord reinforcement: The standard steel cords have been hot-dip galvanised and have diameters from 2.6 to 12.8 mm. They are manufactured in 7x7 or 7x19 designs (other designs are possible). Their design allows good rubber saturation and distribution. Skim layers: A special chemical process provides excellent rubber/metal adhesion in the steel cord conveyor belt. The design of the steel cords leads to outstanding adhesion that surpasses any standards. Good rubber saturation and high adhesion on each cord provide germanBelt® steel cord conveyor belts with extraordinarily high longevity. Covers: The covers’ abrasion resistance, tensile strength and elongation value depend on the quality of the chosen combination of covers of the steel cord conveyor belt. Lateral reinforcements: The steel cord conveyor belts’ reinforcements consist of lateral steel cords with very high elasticity, or of textile fabric. The lateral reinforcements are worked into the carcass or the cover.

The gas cyclone belongs to the mostly applied technical separators, because it has applicationwise some fundamental advantages. One of them is certainly the fact that its construction does not show any movable components. For the large variety of different kinds of dispersed (particulate) phases (for example dust particles, metal chips, wooden waste, liquid droplets) and different gas conditions (pressure, temperature) the lay out and computation of a cyclone is still a complex task. Suvis has specialised in the development and lay out of cyclone separators and can offer professional solutions and consulting in the area of gas cyclones. Many years of experience gained through numerous cyclone development projects results in optimal solutions for our customers. A cyclone separator applies centrifugal forces and represents an effective apparatus for separating gas, liquid or solid particles from a continuous phase in chemical, process or environmental engineering.

Chemical Process Industry / Oil & Gas Industry Our vacuum and compressor systems maximize output and efficiency while minimizing maintenance and environmental pollution. Made of stainless steel and other sophisticated materials, they handle explosive and corrosive gases safely and efficiently. Pulp & Paper Industry Providing vacuum pumps and related equipment to the pulp & paper industry is a Gardner Denver Nash specialty. We are well known as an industry leader in engineered vacuum systems and water removal for paper machines. NASH vacuum pumps are used throughout the forming and press sections of a paper machine. Power Industry For over half a century, NASH has been the manufacturer of choice for air removal systems in steam cycle power generation plants throughout the world. NASH condenser exhauster packages efficiently remove inward air leakage from the condenser and improve the efficiency of the turbine under all operating conditions. Other Industries For more than 100 years, Nash has engineered liquid ring vacuum pumps, liquid ring compressors and engineered systems for the toughest applications. Our systems operate dependably for decades in filter applications, refineries, the sugar industry, in the food processing industry, mining and many more applications.

1500 - 19000 CFM / 3,000 to 9,500 m³/h Nash's 2BE3 and 2BE4 series compressors have capacities ranging from 1,500 to 19,000 CFM (2,500 to 33,000 m³hr). Designed to operate in demanding environments like the paper, power, mining and chemical process industries, these compressors offer durability and reliability at a low cost of operation. Each model is equipped with an application-proven polyisoprene-lined body for added corrosion & erosion resistance. The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. In installations where space is limited, the top discharge capability of the 2BE3 and 2BE4 allows the use of a top mounted discharge separator that saves floor space and eliminates the need for a trench. These compressors allow efficient operation over the entire vacuum range without the need to change the compressors's internals. When equipped with a center shroud, split vacuum operation up to 12 in. Hg (400 millibar) differential can be achieved. Large inspection ports allow easy access to pump internals for inspection and maintenance. For more aggressive applications, stainless steel, stainless steel clad and epoxy coated components are available.

3000 - 16000 CFM / 5,100 to 27,200 m³/h The NASH 905 is a redesign and upgrade of the NASH 904. Capacities of the 904 pumps range upward from about 3,000 CFM at vacuum. These durable compressors can handle excess liquid carryover without any difficulty, even if it arrives as massive slugs. 904 compressors are found in many industries, including Paper, Chemical, and Mining. The 905 series has been designed to provide superior reliability and performance in harsh applications such as chemical processing or geothermal power generation. Constructed of 316L stainless steel, the 905 series offers excellent corrosion resistance and can be outfitted with a variety of mechanical seals. It also includes a patented gas scavenging feature.

14000 - 22000 CFM / 24,000 to 38,000 m³/h Designed to operate in demanding environments such as paper, power, mining and chemical process industries, this pump combines durability and reliability with low operating costs. The P2620 has a polyisoprene-lined body for corrosion and erosion resistance. This is a standard feature. The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. Bottom and side discharge connections offer flexibilty to address installation space constraints. The P2620 pump allows efficient operation over the entire vacuum range without the need to change the pump's internals. When equipped with a center shroud, split vacuum operation up to 10 in. Hg (340 millibar) differential can be achieved. Large inspection ports allow easy access to pump internals for inspection and maintenance. Performance ranges from 14,000 to 22,000 CFM (24,000 to 38,000 m³/hr). For more aggressive applications, stainless steel, stainless steel clad and epoxy coated components are available.

3000 - 16000 CFM / 5,100 to 27,200 m³/h The NASH 905 series has been designed to provide superior reliability and performance in harsh applications such as chemical processing or geothermal power generation. Constructed of 316L stainless steel, the 905 series offers excellent corrosion resistance and can be outfitted with a variety of mechanical seals. It also includes a patented gas scavenging feature. All 904 models are still available from Gardner Denver Nash, the original designer and manufacturer.
