NASH - ZWEIGNIEDERLASSUNG DER GARDNER DENVER DEUTSCHLAND GMBH

100 - 3600 CFM / 170 to 6,100 m³/h The NASH SC vacuum pump and compressor, which replaced the popular NASH CL pump in the 1980's, is still being manufactured at Gardner Denver Nash. The SC pump, more flexible and simpler to install and easy to maintain, made it a very reliable pump to be used in many applications. SC pumps are found in applications including: autoclaves, chucking, container filling, labeling and forming, cooking, deaerating, deodorizing food and fats, drying, evaporating, eviscerating, exhausting, extruder venting, fiber setting, filtering, forming, gas stripping, laboratory central vacuum systems, medical and dental vacuum draining, molding, pickup and conveying, priming, slot extraction, and solvent recovery. All SC models are still available from Gardner Denver Nash, the original designer and manufacturer. Whether you have an existing SC pump running in your plant that is in need of service, repair, or replacement with a new or remanufactured duplicate SC pump, Gardner Denver Nash is there for all of the above.

For over half a century, NASH systems have been the products of choice for air removal systems in steam cycle power plants throughout the world. By reducing the energy loss due to air leakage into the condenser, our vacuum systems save millions of dollars worth of energy every day.

From the first planning to shipment, every project is accompanied by one constant contact person. Depending on industry, process and specification, the best material (steel, stainless steel, duplex materials, titanium, plastic material) is chosen. There is a big importance to consider and meet the different standards and rules. Whether its DIN, ISO, ATEX, GOST ASME or PED (pressure equipment directive) - Nash engineers know all these general frameworks and restrictions. Our team of engineers finds the best solution to realize the customer's requirements.

Gardner Denver Nash’s HP and NAB compressors are the ideal choice for recovering fuel gas and condensing valuable hydrocarbons, making more money for the refinery. When reviewing the total life cycle cost of a flare gas compressor system, the NASH liquid ring system provides more value and better reliability than any other technology, hands down. Liquid ring compressors run cool and they clean the gas as they compress it–eliminating the need for downstream aftercondensers and scrubbers. The result is a simpler, more reliable system.

This was achieved through extensive R&D efforts, resulting in innovative design improvements. Nash has designed and manufactured hybrid systems since 1979, and our hybrid systems are recognized worldwide for reliable performance and low greenhouse gas emissions. As the new standard for Nash hybrid designs, these systems maintain traditional benefits, while offering accelerated payback through increased energy savings, condensers designed per HTRI specifications and a faster response time through regional sourcing. Nash is the only company to manufacture both the pumps and ejectors that go into a hybrid system, and offers a complete system warranty. All Nash hybrid systems are backed by global aftermarket support, decades of engineering expertise, and a proven history of reliable, dependable installations. Existing all ejector systems can be upgraded to more efficient hybrid systems by replacing or modifying stages. Nash engineers can evaluate your specific systems and recommend a custom hybrid design that will optimize your energy savings. Through reduced operating costs, upgraded systems can offer a payback of 2 years or less. Nash hybrid systems are used in industries and applications where deep vacuum is required and system reliability is critical. In operations where efficiency is key, emissions are a concern, or if there is a scarcity of steam in the plant, Nash hybrid systems are the optimal solution for efficiency.

All components pass a quality inspection before being used. Many different methods and procedures are used here (e.g. PMI 0 positive material inspection, crack detection). Our scope of machining reaches from chipping/metal cutting to sandblasting (using granule materials) to welding, assembling and painting. We handle many different metallic and nonmetallic materials as steel, stainless steel, duplex materials, titanium, plastic material We give a big importance to welding: Nash employees are certified according to ASME 9 and therefore qualified to manufacture pressure vessels and piping according to Pressure Equipment Directive (DIN EN 3834) and ASME Standards (31.3). Our systems are painted according to customer specification. We work with all wet paints and 2K paints. Anti-corrosion-coatings up to category C5M are possible. Of course, we meet all the other specifications, e.g. regarding coating thickness, as well. The electrical engineering is also done in the Nash location, from design to cabling. After the completion, the system undergoes a pressure test. Furthermore there is an option to do a complete function test to verify the performance data. Nash is certified according to ISO 9001 and ISO 14001.

0-29 in HgV (to 33 mbar abs) If you thought you couldn't afford the water costs associated with operating a liquid ring pump…think again. One of the wonderful features of the liquid ring pump is that it can be operated with a multitude of different fluids. A self-contained oil sealed system has a number of benefits over a traditional water sealed system: It eliminates water usage and disposal costs; it allows you to install it in remote locations where water may not be available; it allows you to attain higher vacuum levels than with water; it can prevent the condensing or dissolving of a process gas; it permits anhydrous processing with a liquid ring pump. Self contained system complete with off of the components for your basic operating needs. Standard components include: pump, TEFC motor, coupling or v-belt drive, drive guard, separator with oil mist eliminator, air cooled heat exchanger, recirculated seal line controls and high temperature alarm switch. Options include: inlet isolation valve, inlet check valve, vacuum relief valve, inlet filter, control panel and system skid plate. An oil sealed liquid ring system is more tolerant of carryover and wear, and it provides quiet operation. The oil is not required for lubrication which means it can operate at extremely long intervals between oil changes, easily going more than 10,000 hours with no down time. Aside from a periodic oil and filter change, the system can run for years with no scheduled maintenance. If your process requires very deep vacuum, Gardner Denver Nash has the solution. Using a two-stage liquid ring pump in an oil sealed system, vacuum levels lower than 10 Torr (29.6" HgV) can be attained.

These Duplex Vacuum Systems consist of an air ejector, two Vectra XL350 liquid ring vacuum pumps, interconnecting piping and related instrumentation. The vacuum pumps and ejector are manufactured in Aluminum Bronze and the piping interconnections are manufactured in Fiberglass Reinforced Epoxy. These special materials of construction ensure the usual Nash reliability even in the harsh conditions of offshore production.
