描述

凭借数十年的可行性能，2BE1液环真空泵和压缩机系列继续为几乎全部工业真空应用提供经济快效、可行的真空解决方案。2BE1产品系列有23种型号，涵盖各种容量尺寸，结构材料有铸铁、不锈钢，以及两者结合。  

基于经过证明的平圆盘2BE设计，坚固耐用且低维护

Nash的平圆盘液环真空泵/压缩机设计于二十世纪初在德国获得自主研发设计，已向全球数千个工厂提供，具有经过证明的性能、可行性，使您高枕无*。凭借不断创新，Nash的自主研发设计设计具有以下特点：

圆盘具有可变端口，因此泵的性能在整个工作范围内得到优化。

大压差能力

液体残留物耐受性高

大型检查端口便于内部检查

关闭时，孔口可以*全排空泵

作为真空泵和压缩机运行时，其排放压力范围为50 psia（3.5 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。

NASH经典型号的泵

凭借110多年液环真空泵和压缩机制造经验，我们知道如何设计持久的产品。因此，我们仍在生产如2BE1这样的经典液环真空泵和压缩机，而且它们还在世界各地的工厂运行。只有佶缔纳士制造的真正经典产品才100％经过性能测试且具有出厂保修。

Liquid Ring Vacuum Pump

Medium Capacity, 2BE1

Capacity 60 to 13,000 ACFM (100 to 25,500 m3/h)

The NASH 2BE1 liquid ring vacuum pump and compressor series covers a broad range of suction volume, vacuum, and pressure. Based on the proven reliable flat sided liquid ring vacuum pump design the 2BE1 is available in 23 models, has a large differential pressure capability, and is ATEX Certified. For these reasons, the 2BE1 is one of the most popular liquid ring pumps worldwide and can be found in almost all industrial vacuum applications including the chemical, pulp & paper, and power generation industries.

Description

Backed by decades of reliable performance the 2BE1 liquid ring vacuum pump and compressor series continues to offer a cost-effective, reliable vacuum solution for almost all industrial vacuum applications. Available in 23 models, the 2BE1 product line covers a wide range of capacity sizes and is available in cast iron, stainless steel, and a combination of both materials.  

Robust and low maintenance based on proven flat sided 2BE design

Patented in Germany in the early 1900’s, Nash’s flat sided liquid ring vacuum pump/compressor design has been providing thousands of facilities across the globe with proven performance, reliability, and peace of mind. With constant innovation, Nash’s patented design features:

Port plates with variable porting so pump performance is optimized across the entire operating range.

Large differential pressure capability

High liquid carryover tolerance

Large inspection ports allow for easy internal inspections

Orifice to drain pump completely when shut down

Operates as a vacuum pump and compressor with a discharge pressure range of 50 psia (3.5 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 Pump Model

With more than 110 years of experience engineering liquid ring vacuum pumps and compressors, we know how to design products that last. As a result, our Classic liquid ring vacuum pumps and compressors, like the 2BE1, are still manufactured and are running in plants around the world today. Only true Classics manufactured by Gardner Denver Nash are * performance tested and carry our factory warranty.
