Nash created the first liquid ring vacuum pump more than 110 years ago and is still the industry leader in the market segment today. They manufacture liquid ring vacuum pumps, compressors and engineered-to-order systems that provide performance, reliability and efficiency. Today Nash has expanded its product portfolio to offer a complete range of vacuum solutions, including liquid ring pumps and compressors from Nash and Garo, Dry-Pro dry vacuum pumps, Ener-Jet steam ejectors and hybrid vacuum systems, and Wittig rotary vane compressors and vacuum pumps.
NASH Liquid Ring Vacuum Pumps
CL Vacuum Pumps and Compressors
A NASH Classic. The NASH CL vacuum pump and compressor line is perhaps the most popular ever built. Available only from NASH, there are 12 different models, from the CL-200 through the CL-14000, with capacities ranging from 150 CFM to over 14,000 CFM.
2BE3 & 2BE4 Liquid Ring Vacuum Pumps & Compressors
A NASH Classic. The NASH 2BE3 and 2BE4 vacuum pump and compressor series offers capacities ranging from 1,500 to 19,000 CFM (2,500 to 33,000 m³/hr). Designed to operate in demanding environments like the paper, power, mining and chemical process industries, these pumps 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.
2BE5 Liquid Ring Vacuum Pumps & Compressors
The NASH 2BE5 is the next generation of the NASH 2BE line of flat sided vacuum pump/compressor design. Offering higher vacuum capabilities with improved efficiency, the NASH 2BE5 serves a wide range of industrial applications.
Vectra GL / XL Vacuum Pumps
Vectra GL/XL Vacuum Pumps 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.
Vectra SX Pumps and Compressors
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.
904 Liquid Ring Vacuum Pumps & Compressors
A NASH Classic. The NASH 904 replaced the popular NASH CL pump in the 1980's, and is still available from NASH, the original manufacturer. . Capacities of the NASH 904 pumps range upward from about 3,000 CFM at vacuum. These durable pumps can handle excess liquid carryover without any difficulty, even if it arrives as massive slugs. 904 pumps & compressors are found in many industries including Paper, Chemical, and Mining.
905 Vacuum Pumps
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.
AT Two Stage Vacuum Pumps
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.
TC/TCM Two Stage Vacuum Pumps
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.
P2620 Vacuum Pump
Leading the large pump market are Nash's P2620 vacuum pumps with capacities ranging from 14,000 to 22,000 CFM (24,000 to 38,000 m³/hr). Designed to operate in demanding environments like the paper, power, mining and chemical process industries, these pumps 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.
Marine Duty Vacuum Pumps
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.
Priming Valves
Nash priming valves were designed specifically for Nash vacuum pump priming systems. They are extremely simple, durable and dependable.
2BE1 Liquid Ring Vacuum Pumps and Compressors
A NASH Classic. The NASH 2BE1 series is one of the most successful liquid ring pumps worldwide. With a broad range of suction volume, vacuum and discharge pressure, pumps in this series are used in almost all industrial applications.
2BM1 - Hermetically Sealed Pumps & Compressors
Capacity to 877 cfm, Vacuum to 1" Hg abs, Compressor Pressure to 5.8 psig. Using a magnetic drive to achieve non-contact torque transmission, the 2BM Series offers leak free performance and is hermetically sealed.
2BM5 – Hermetically Sealed Pumps & Compressors
Capacity to 270 cfm, Vacuum to 1" Hg abs, Compressor pressure to 21.7 psig. Using a magnetic drive to achieve non-contact torque transmission, the 2BM Series offers leak free performance and is hermetically sealed.
