Youcan count on Gardner Denver Nash to designand deliver the right solutions for your vacuumpump and compressor system application. As aworldwide leader in vacuum technology,Gardner Denver Nash has the expertise andknowledge to ensure that you receive the bestproduct for your application.We don't just sell something off the shelf. Wetake the time to determine what your needsare through a comprehensive analysis of yourprocess. We then design the system to meetyour specific requirements beginning with thefundamentals - capacities, vacuum or pressurelevels and the unique demands your processwill require. We take into consideration yourobjectives relative to operating costs andinitial capital investment. Then, we engineer aNASH system to satisfy all of your needs.The Liquid Ring AdvantageFeaturesLiquid ring vacuum pumps and compressors that use a fluidcompressant in lieu of pistons, vanes or rotating lobes are the bestchoice in most applications. They provide benefits that are notpossible with other alternatives.Gardner Denver Nash easily complies with ATEXrequirementsbecause of the isothermal compression that is characteristic ofliquid ring pumps. Simply put, NASH pumps run much coolerthan other technologies.BenefitsAbility to handle carryoverMinimal process problems;Intended for severe milland chemical duty useLong design lifeHighest reliabilityNo internal lubrication requiredNo routine maintenancerequired; less downtimeNo metal-to-metal contactConstant wear-free performanceCool Running,Minimal temperature risebetween inlet and dischargeIdeal for explosive gases andvapor recovery applicationsOnly one moving partSimple and reliable operationChemicals HandledUnlike other vacuum pumps and compressors, NASH systems can handle moisture-laden inlet streams; explosive gases; dirty, abrasiveor corrosive gas mixtures; and unpredictable streams that change with process variables.

Versatile product technology expertly appliedOur broad range of products, consisting of liquid ring vacuum pumps, liquid ring compressors and ejectors can be individually applied orcombined into packaged systems with additional components to serve a variety of process demands.Liquid ring vacuum pumpsThe NASH liquid ring vacuum pump family providesa wide range of product options. From the topof-the-line heavy-duty P2620 with a dry aircapacity of 23,000 CFM/ 39,000 m3/h to themid-range Vectra (2,800 CFM/ 4,750 m3/h) andthe smaller close-coupled 2BV series, we have theright answer for your individual vacuum requirement.Gardner Denver Nash knows the technology behindliquid ring vacuum pumps, because it invented theliquid ring principle of operation. Liquid ring vacuumpumps operate at low temperatures and are suitable forhandling liquids, steam and condensate. Developed for the toughestapplications, these pumps can safely and reliably extract explosive gasand corrosive vapors.Requiring minimal care and known for extremely low maintenance,NASH liquid ring vacuum pumps provide years ofdependable service due to their robust design,rigorous quality, and theirfewer and generouslyproportioned parts.Thanks to their lowoperating costs andextensive performancerange up to 23,000 CFM/39,000 m3/h, they excelin any application.NASH VECTRANASH 2BVNASH TC/TCMLiquid ringcompressorsGardner Denver Nash offers the widestpressure and capacity ranges of liquid ringcompressors worldwide. Together with theimpressive NASH HP-9 and the introductionof the 14 over-hung models, NASH's highpressure compressor product line providescompression greater than 200 PSIG/15 Bar abs and up to 2,500 CFM/ 4,250 m3/hper machine. Low-pressure compressors areavailable to 30 PSIG/ 3 Bar abs, and as much as20,000 CFM/ 34,000 m3/h.Found primarily in petroleum refineries and chemical plants,these rugged and reliable compressors handle highly toxic,explosive and corrosive gases in applications such as flare-gas,chlorine and Vinyl Chlorine Monomer (VCM) recovery.NASH HP-9

Complete application solutionsOur goal at Gardner Denver Nash is to provide long life,reliable, low maintenance and energy efficient solutions toprocesses like: evaporation, distillation, vacuum filtration, gascompression, VOC recovery, solvent recovery and drying.We produce a complete range of products and systems forindustries including:ChemicalPetrochemicalWater ve Gas CompressionVCM RecoveryA typical arrangement for handling explosive gases, thiscompressor system keeps acetylene cool and saturated withwater, which is used as the seal liquid. By doing this, therisk of explosion is minimized.In one of several batch monomer recovery systems, unreacted vinylchloride is first transferred into the evacuated holding tank. ANASH vacuum pump scavenges gas out of the PVC and delivers itto the compressor inlet at or near atmospheric pressure. The singlestage compressor then compresses the gas for condensation andstorage as a pressurized liquid.140 psigACETYLENEGAS at 0 NASHVACUUMPUMPCOOLERPolymerization ReactorVOC RecoveryTo eliminate plugging from polymer carryover, NASH ejectorsare driven with ethylene glycol vapor. Liquid ethylene glycol isthen used as the vacuum pump seal liquid and also to coolthe direct contact condensers. This eliminates processcontamination from water, steam and air.Vacuum tumble-drying performed in batch processing requires agradually increasing vacuum to draw out solvents at the maximumsustainable rate. Often times this same solvent can be used as thepump seal liquid and motive vapor in the ejector to operate theprocess. Contamination is eliminated and pure solvent is recovered.LIQUIDEGVAPOREG PUMPNASHVACUUMPUMPVACUUMTUMBLEDRYERETHYLENE GLYCOL RECEIVERSOLVENTSTORAGECOOLERSeal Liquid OptionsWater is an excellent seal liquid and is most often used due to its availability and convenience. There are many situations, however,where alternative seal liquids may yield important process advantages or where even trace amounts of water cannot be tolerated inthe product.In these instances, NASH vacuum pumps have demonstrated their versatility by successfully operating with a variety of other liquids.These liquids include:Acetic AcidAcetic AnhydrideAcetatesAcetoneAlcoholsCaustic tor FluidKeroseneMEKOilsSulfuric AcidTolueneXyleneand many others
