Former trade mark

Vacuum pumps supplied by NASH inherits from merging between NASH Engineering Company USA and ELMO vacuum technology GMBH Germany in 2002. NASH is a product of Gardner Denver Co.

Range of products for power plants

NASH offers the following vacuum products:

Engineered systems

• Condenser Exhauster Systems,
  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.

 

 

• VectraPak Vacuum Systems,
  The pre-engineered VectraPaks are a versatile and readily available system for any industrial vacuum need. The Vectrapak comes with the accessories already mounted and piped for ease of installation. They are available from 150 to 3000 ACFM, suitable for operation to 29" HgV, and are available in both iron and stainless steel construction.

Liquid Ring vacuum pumps

NASH provides its customers with reliable, quality liquid ring vacuum pumps with the features and performance necessary for all demanding applications.

Key Facts for the NASH Liquid Ring Vacuum Pumps:

• Vacuum pumps from 20 CFM to 23,000 CFM
• Vacuum pumps to 29+" HgV
• Vacuum pumps designed to operate safely, cleanly and continuously in wet environments.
• Require minimal care - known for extremely low maintenance.
• Provide years of dependable service and quality liquid ring vacuum pumps due to fewer, generously proportioned parts.
• Reduce power and operating costs of liquid ring vacuum pumps, handling higher capacities with less energy/power.
• NASH is the inventor of the liquid ring principle of operation
• Corrosion resistant and explosion proof pumps available

Types of pumps

P2620 Vacuum Pumps

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.

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.

AT Two Stage Vacuum Pumps

The popular NASH AT two stage vacuum pumps have been providing reliable high vacuum perfomance 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 ian deal choice when you a rugged and long lasting machine to handle your staurated process gases.

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.

Steam Jet Ejectors

Steam ejectors provide vacuum in many process industries and utility companies. Combining low capital cost, simple operation, high reliability and the ability to handle large volumes at very high vacuum levels, they can be optimized to contribute to process enhancement and operational efficiency.

The steam jet ejector

• Are available in a wide variety of materials
• Designs for ejectors range in size from a one inch inlet to a 78 inch (2 m) inlet
• Ejectors have matching standard barometric condenser designs
• Require no moving parts, translating into trouble-free continuous operation
• Operate efficiently for high vacuum and high volumetric flow requirements
• Are manufactured and tested (actual ejector or pilot ejector) per HEI standards to guarantee performance
• Are most suitable for minimizing capital cost, particularly on batch process applications
• Reduce operating costs when optimized in stages with Nash liquid ring vacuum pumps. These hybrid systems also enhance vacuum stability
