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 Large Capacity, P2620 Capacity 14,000 to 21,800 ACFM (23,800 to 37,000 m3/h) The NASH P2620 liquid ring vacuum pump model allows efficient operation over the entire vacuum range without the need to change the pump's internals. With the largest capacity in our portfolio, ranging from 14,000 to 21,800 ACFM (23,800 to 37,000 m3/h), the P2620 is designed to operate in demanding environments such as paper, power, mining, and chemical process industries. Split Vacuum Capability When a NASH P2620 vacuum pump is equipped with a center shroud, split vacuum operation up to 10 inHg (340 millibars) differential can be achieved. The advantage of this is significant, allowing usage of fewer vacuum pumps - which saves space and installation costs. Flexible Installation & Quiet Operation The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. Bottom and side discharge connections offer flexibility to address installation space constraints. Large inspection ports allow easy access to pump internals for inspection and maintenance. 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.
