描述

快效、可行、性能優(yōu)佳

905液環(huán)真空泵和壓縮機系列是經(jīng)過證明的904型的升級產(chǎn)品，其設(shè)計旨在提供經(jīng)改進的性能和可行性。

905以經(jīng)改進的可變端口設(shè)計降低生命周期成本，擴大操作范圍，提快效率，節(jié)水和使用更簡單的密封管道。它還包括獲得自主研發(fā)設(shè)計的GSV設(shè)計，可在高度真空下提供優(yōu)佳的性能和使用壽命。

專為要求苛刻的環(huán)境而設(shè)計

905系列設(shè)計為向化學(xué)處理、造紙、采礦、地?zé)岚l(fā)電或任何需要可行壓縮腐蝕性氣體的惡劣應(yīng)用提供可行的操作和性能。905由316L不銹鋼制成，具有出色的耐腐蝕性，可使用各種機械密封。

作為真空泵和壓縮機運行時，其排放壓力范圍為36 psia（2.5 bar abs.)

某些應(yīng)用需要在某道工序中抽真空和壓縮。我們的液環(huán)真空泵和壓縮機可以在一臺泵中處理氣體，而不需要在兩臺獨立的機器中完成 - 降低了成本并簡化了安裝。

Liquid Ring Vacuum Pump

Large Capacity, 905

Capacity 2,800 to 13,000 ACFM (4,800 to 22,000 m3/h)

The NASH 905 liquid ring vacuum pump series has been optimized to deliver superior reliability and performance over the existing 904 and CL models. With capacities ranging from 2,800 to 13,000 ACFM (4,800 to 22,000 m3/h) the 905 is ideal for applications such as chemical processing, paper, mining, geothermal power generation or anywhere reliable compression of corrosive gases is needed.

Description

Efficient And Reliable With Proven Performance

The 905 liquid ring vacuum pump and compressor series is an upgrade to the proven 904 model and has been engineered to deliver improved performance and reliability.

The 905 provides lower life-cycle costs with an improved variable port design, enabling a wider operating range with improved efficiency, water-saving technology, and simpler seal line piping. It also includes a patented gas scavenging feature to provide superior performance and longevity at high vacuum levels.

Designed To Operate In Demanding Environments

The 905 series has been engineered for reliable operation and performance in harsh applications such as chemical processing, paper, mining, geothermal power generation, or anywhere reliable compression of corrosive gases is needed. Constructed of 316L stainless steel the 905 offers excellent corrosion resistance and can be outfitted with a variety of mechanical seals.

Operates As A Vacuum Pump & Compressor With A Discharge Pressure Range Of 30 psia (2 bar abs.)

Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.

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
