P2620 pumps are amazingly quiet during operation. Sound levels of 72 to 85 dB(A) (measured at a distance of 3.3 ft (1 meter) from the source) have been recorded for even the largest of the pump models. Designed To Operate In Demanding Environments Designed to operate in demanding environments like the paper, power, mining, sugar, and chemical process industries, these pumps offer durability and reliability at a low cost of operation. The standard polyisoprene lining on the P2620 vacuum pump body resists aggressive process gases and liquids to provide exceptional corrosion resistance. The polyisoprene lining also consumes less energy than the equivalent unlined pump.

How Liquid Ring Vacuum Pumps Work Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical, electrical power, environmental, food & beverage processing and packaging, marine, mining, oil & gas, pharmaceutical, pulp & paper, and textiles. Liquid ring vacuum pumps utilize water or other processes compatible liquid as the sealant. The simple operation, with no contacting parts, make liquid ring vacuum pumps a safe and reliable choice for handling dirty and potentially dangerous gas streams. Liquid ring pumps are available in single and dual stage designs and also configured as compressors for even more versatility. Principle Of Operation The seal liquid forms the ring inside a pump body as the impeller spins creating small chambers for gas to be trapped. The axis of the rotor is eccentric from the body allowing the liquid to almost fill, and then almost empty each rotor chamber during a single revolution, forming the compression of the gas for the pumping action. Vacuum inlet and atmospheric discharge ports provide flow paths for the gas mixture being handled. The heat of compression of the gas is dissipated into the seal liquid, and some of the liquid flows out to discharge. The exhaust gas and residual water discharge is separated from the gas stream and directed to the house exhaust and returned to the pump respectively. Seal fluid is replaced by a constant flow of cooler seal fluid. Characteristics Of Liquid Ring Vacuum Pumps Accepts Carryover - Soft solids, moisture, slugs, chemicals and more will not harm the pump. These impurities will simply be washed out through the pump discharge. Cool & Quiet Operation - The pump runs cool owing to the circulation of the sealing water inside the pump. The operation is relatively quiet - not exceeding 85 dBA. Constant Operation For Any Vacuum Level - Pump can operate constantly and continuously at any vacuum level - from 29 in. Hg to atmospheric pressure. NASH Liquid Ring Vacuum Pump - How it Works Easy Maintenance & Longer Pump Life - Liquid ring vacuum pumps are robust in construction and have only one moving part, the rotor, which is mounted on a shaft supported by a set of bearings designed for a long service life of continuous operation. This benefits the user with less wear and simpler, affordable maintenance. Environmental - Pumps do not require an oil change, filter, oil-pans, condenser or etc. For that reason, plant rooms run clean, free of oil contamination and oil discharges to sewers. A Look Inside A Liquid Ring Vacuum Pump The Technology Behind Liquid Ring Vacuum Pumps The design technology behind liquid ring vacuum pumps is advanced to achieve optimum, reliable performance for the rigorous demands of harsh industrial environments. Liquid ring vacuum pumps are an economical and robust solution engineered to meet specific customer requirements. Condensation Of Vapors Can Yield A Capacity Bonus Dry air or a dry gas mixture is compressed from vacuum to atmospheric pressure in a liquid ring pump much the same way as it would be in any other displacement type pump, except that there is less of a temperature rise of the gas stream through the pump. Humid air or gas mixtures containing condensable vapor behave quite differently. Some of the vapor that enters a liquid ring pump condenses when it is cooled by the lower temperature seal liquid. The condensate mixes with the seal liquid. Now, it occupies a much-reduced space as contrasted with its former volumetric dimension when it was a component of the inlet gas stream. This volumetric reduction becomes a capacity bonus. The only vapor that can be condensed early enough to escape compression contributes to the inlet capacity bonus. In each rotor chamber, the condensation must occur before that chamber passes its inlet port. Any condensation that occurs after the cutoff will not have an effect on pump inlet capacity. Liquid ring vacuum pumps can handle large amounts of liquid through its inlet port with a negligible reduction of gas capacity. To maximize the condensation bonus some of the liquid is often sprayed into the inlet piping, upstream of the vacuum pump itself.

Additional Wording Nash – AT Two Stage Vacuum Pump The popular NASH AT two stage vacuum pumps have been providing reliable high vacuum performance in the power industry for nearly 50 years. Category: Vacuum Tag: Energy & Utilities Description Additional information Description The popular NASH AT two stage vacuum pumps have been providing reliable high vacuum performance in the power industry for nearly 50 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. Liquid Ring Vacuum Pump Two Stage, AT Capacity 400 to 2,800 ACFM (680 to 4,750 m3/h) The popular NASH AT two stage vacuum pump series has been providing reliable high vacuum performance in the power industry for over 25 years. With capacity ranging from 400 to 2,800 ACFM (680 to 4,750) the AT's four vacuum pump models are an ideal choice when you need a rugged and long-lasting machine to handle your saturated process gases. Designed to Operate in Harsh Conditions The line of AT vacuum pumps is our first generation of two stage pumps designed specifically for the condenser exhaust duty. Including an integral two stage rotor, the AT vacuum pump is designed to reach vacuum levels down to 0.8 inHgA (30 mbar abs). This is approximately 40% lower absolute pressure than a single stage pump. AT liquid ring vacuum pumps were created for the chemical, petrochemical, and power industries. With their integral two stage rotors, AT pumps, are able to condense vapors that come off the process and to recover or dispose of them. Conical Porting and Rotor Configuration Patented in 1932, Nash’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, Nash’s patented design features: Option for lobe purge to minimize damage from erosion in duties with solids present Large differential pressure capability Gas scavenging feature minimizes slip of gas from discharge to inlet improving capacity, especially at deep vacuum High liquid carryover tolerance Side discharge to minimize chance of flooded start Self-priming design may allow elimination of booster pump in recirculated systems Reliable and Efficient with Proven Performance The AT offers superior performance and reliability through the proven reliable NASH conical liquid ring pump design. The first AT3006 vacuum pump was built and tested at a Gardner Denver Nash facility with results showing an increased dry air capacity up to 25% in the high vacuum range without an increase in power usage. The AT3006 offers higher operating efficiency than the AT3004, and with today's energy costs, efficiency is an important factor for our customers. 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.
