描述

專為在各種應用中運行而設計

SC單級泵和壓縮機是*端惡劣條件下更苛刻應用的理想選擇，包括：滅菌器、夾具、容器灌裝、標簽和成型、烹飪、脫氣、食品和脂肪除臭、干燥、蒸發、去內臟、排氣、擠出機排氣、纖維凝固、過濾、成型、氣體剝離、實驗室中央真空系統、醫療和牙科真空系統、制模、拾取和輸送、灌注、提取槽和溶劑回收。  

可行、快效的錐形端口和轉子

Nash的可變錐形端口設計于1932年獲得自主研發設計，使壓縮力抵消轉子和軸的重量，從而盡量減少軸承的運行負荷。可變端口在整個工作范圍內優化泵的性能。憑借不斷創新，Nash的自主研發設計設計具有以下特點：

?可選擇的凸輪清洗方法，以盡量減小涉及固體的工作中侵蝕造成的損害

?大壓差能力

?GSV設計可更大限度地減少氣體從排放口漏到入口，從而提高容量，特別是在深度真空時

?液體殘留物耐受性高

?側面排放，以盡量減少滿液啟動的可能

?自吸設計可消除在再循環系統中使用增壓泵

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.)

某些應用需要在某道工序中抽真空和壓縮。我們的液環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

Medium Capacity, SC

Capacity 70 to 1,150 ACFM (120 to 2,000 m3/h)

The NASH SC liquid ring vacuum pump and compressor series is a reliable and flexible alternative to the popular NASH CL series. Designed as an upgrade to the existing CL models, the SC series delivers proven performance with flexible installation options and reduced maintenance requirements. Available in 9 models, the capacities of the SC pumps range from about 70 to 1,150 ACFM (120 to 2,000 m3/h). SC pumps and compressors are typically found in food and general industrial applications.

Description

Designed to Operate in a Myriad of Applications

SC single stage pumps and compressors are ideal for the most demanding applications in extremely tough conditions, including autoclaves, chucking, container filling, labeling and forming, cooking, deaerating, deodorizing food and fats, drying, evaporating, eviscerating, exhausting, extruder venting, fiber setting, filtering, forming, gas stripping, laboratory central vacuum systems, medical and dental vacuum draining, molding, pickup and conveying, priming, slot extraction, and solvent recovery.  

Reliable and Efficient with Conical Porting and Rotor

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

Operates as a vacuum pump and compressor with a discharge pressure range of 20 psig (2.4 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.

NASH Classic

With more than 100 years of experience producing liquid ring pumps, we know how to design pumps and compressors built to last. As a result, our Classic liquid ring vacuum pumps and compressors, like the SC are still manufactured by Gardner Denver Nash and are running in plants around the world today. Only true Classics manufactured by Gardner Nash are * performance tested and carry our factory warranty.
