NASH - ZWEIGNIEDERLASSUNG DER GARDNER DENVER DEUTSCHLAND GMBH

The NASH 2BE5 was developed from the proven NASH 2BE3 and 2BE4 pumps, whose reliable performance has been further improved. The development focused on optimizing performance, higher vacuum capabilities and ease of maintenance. NASH 2BE5 Benefits include: improved efficiency higher vacuum levels (to 100 mbar abs / 3" Hg abs) built-in ECO-FLO™ water saving technology with patent pending gas scavenging drop in replacement for 2BE3 and 2BE4 removable bearing brackets for easier maintenance elimination of tie rods, resulting in improved sealing due to bolted casing joints polyisoprene lining The footprint and connections to the NASH 2BE5 models are identical to its predecessors, the NASH 2BE3 and 2BE4. Therefore, exchanging or upgrading to the more efficient NASH 2BE5 requires no site modifications. The NASH 2BE5 model is available in cast iron, with stainless steel coming soon. The 2BE5 is perfect for use in mining, filter applications, paper mills, power plants, chemical plants, refineries and more.

Suction capacity 125 to 1400 m³/h; Vacuum to 33 mbar abs.; Discharge pressure to 2.0 bar abs. The NASH 2BM1 magnetic drive pump series is capable of achieving volume flow rates of 125 to 1400 m³/h and vacuum of 33 mbar abs. Non-contact torque transmission is achieved by using a permanent magnetic drive system. The pump's inner working space is hermetically sealed from atmospheric conditions, eliminating any possibility of leakage. This seal is essential for demanding applications, such as processes that are required to meet the most stringent standards on environmental compatibility. ATEX applications are also possible, certifications 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. Whether you have an existing 904 pump running in your plant that is in need of service, repair, or replacement with a new or remanufactured duplicate 904/905 pump, Gardner Denver Nash is there for all of the above.

500 - 2500 CFM The popular NASH AT two stage vacuum pumps have been providing reliable high vacuum performance in the power industry for over 25 years. With four models ranging from 500 - 2500 CFM and vacuum levels as low as 1" HgA, the AT's are an ideal choice when you need a rugged and long lasting machine to handle your saturated process gases. Whether you have an existing AT pump that is in need of service, repair or replacement with a new or remanufactured duplicate AT pump, Gardner Denver Nash is there to meet your needs.

10 - 75 CFM / 17 to 127 m³/h NASH has been providing vacuum pumps and packages in shipboard priming applications for over 50 years and continues to offer a wide range of classic products for this service. The single stage MD570, MD670, MHC, and MHF series are available in a variety of materials including bronze, copper nickel, and stainless steel. These pumps are provided close coupled to a marine duty motor have capacties ranging from 10 to 75 CFM. If deeper vacuum is required, the two stage AT34 & AT64 pumps are available with capacties ranging from 30 to 75 CFM.

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.

Priming Valves for Liquid Ring Vacuum Pumps Gardner Denver Nash priming valves were designed specifically to be used in Nash vacuum pump priming systems. They are extremely simple, dependable and durable. It has been proven in successful service for nearly fifty years. A Nash vacuum system is often used to prime one or more centrifugal pumps located above the free liquid levels of their suction sources. Vacuum draws liquid up until it fills each pump's suction line and floods its volute. This condition can be established before the pump is started up, so that it is always primed and ready to begin pumping.

125-2100 CFM / 210 to 3,560 m³/h The NASH TC/TCM liquid ring vacuum pumps are highly reliable and efficient. These pumps, with their integral two stage impeller, are able to condense process vapors and to recover or dispose of the vapors. Another benefit of these pumps is that they can attain vacuum levels down to 0.8" HgA (20mmHgA). This is approximately 40 percent lower absolute pressure than a single stage pump. The NASH TC and TCM models are designed to handle large amounts of liquid carryover without difficulty. This ensures reliability under the most demanding applications.

15 - 5300 CFM / 195 to 9,100 m³/h The NASH Vectra was designed around a modular platform using the most advanced computer aided design techniques, such as 3D solid modeling and finite element analysis (FEA). The modular platform offers the advantage of two versions with numerous common parts. The Vectra GL model, available from 120 to 830 CFM (200 to 1,500 m³/hr), is ideal for general industrial applications. It comes standard with internal mechanical seals and many Nash patented innovations including gas scavenging. The Vectra XL model was designed to meet the stringent requirements of many CPI applications. Whether operating as a vacuum pump or compressor, it features a 30 PSI (2 bar) differential capability. It is available in ductile iron or 316L stainless steel with a variety of shaft sealing options. Sizes range from 120 to 5,300 CFM (200 to 9,000 m³/hr). The NASH Vectra can be operated within a wide range of operating speeds, with numerous 50 and 60 HZ direct drive speeds. This increased turndown capability makes them ideal for varying load applications when driven by VFD's.

15 - 140 CFM / 35 to 210 m³/h Designed from the ground up to meet the widespread needs of the process industry, the Vectra SX adds five models to Nash’s Vectra series in the 1 ½ to 10 HP range at 60 Hz (0.75 to 5.5 kW at 50 Hz), providing the right solution for small capacity vacuum pump requirements. Designed to use less energy and consume less operating liquid than competitive models, it is possible to save the user as much as 40% on power consumption and 50% on water usage.
