描述
专为在各种应用中运行而设计
SC单级泵和压缩机是*端恶劣条件下更苛刻应用的理想选择，包括：灭菌器、夹具、容器灌装、标签和成型、烹饪、脱气、食品和脂肪除臭、干燥、蒸发、去内脏、排气、挤出机排气、纤维凝固、过滤、成型、气体剥离、实验室中央真空系统、医疗和牙科真空系统、制模、拾取和输送、灌注、提取槽和溶剂回收。
可行、快效的锥形端口和转子
Nash的可变锥形端口设计于1932年获得自主研发设计，使压缩力抵消转子和轴的重量，从而尽量减少轴承的运行负荷。可变端口在整个工作范围内优化泵的性能。凭借不断创新，Nash的自主研发设计设计具有以下特点：
可选择的凸轮清洗方法，以尽量减小涉及固体的工作中侵蚀造成的损害
大压差能力
GSV设计可更大限度地减少气体从排放口漏到入口，从而提高容量，特别是在深度真空时
液体残留物耐受性高
侧面排放，以尽量减少满液启动的可能
自吸设计可消除在再循环系统中使用增压泵
作为真空泵和压缩机运行时，其排放压力范围为36 psia（2.5 bar abs.)
某些应用需要在某道工序中抽真空和压缩。我们的液环真空泵和压缩机可以在一台泵中处理气体，而不需要在两台独立的机器中完成 - 降低了成本并简化了安装。

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.
