NASH 2BE1液環(huán)真空泵和壓縮機系列涵蓋了廣泛的吸氣量、真空和壓力范圍。基于久經考驗、可行的平圓盤液環(huán)真空泵設計，2BE1有23種型號可供選擇，差壓能力較大，且通過ATEX認證。因此，2BE1是全球更受歡迎的液環(huán)泵之一，幾乎可用于全部工業(yè)真空應用，包括化學、紙漿和造紙以及發(fā)電行業(yè)。

描述

憑借數十年的可行性能，2BE1液環(huán)真空泵和壓縮機系列繼續(xù)為幾乎全部工業(yè)真空應用提供經濟快效、可行的真空解決方案。2BE1產品系列有23種型號，涵蓋各種容量尺寸，結構材料有鑄鐵、不銹鋼，以及兩者結合。  

基于經過證明的平圓盤2BE設計，堅固耐用且低維護

Nash的平圓盤液環(huán)真空泵/壓縮機設計于二十世紀初在德國獲得自主研發(fā)設計，已向全球數千個工廠提供，具有經過證明的性能、可行性，使您高枕無*。憑借不斷創(chuàng)新，Nash的自主研發(fā)設計設計具有以下特點：

?圓盤具有可變端口，因此泵的性能在整個工作范圍內得到優(yōu)化。

?大壓差能力

?液體殘留物耐受性高

?大型檢查端口便于內部檢查

?關閉時，孔口可以*全排空泵

作為真空泵和壓縮機運行時，其排放壓力范圍為50 psia（3.5 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(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。

NASH經典型號的泵

憑借110多年液環(huán)真空泵和壓縮機制造經驗，我們知道如何設計持久的產品。因此，我們仍在生產如2BE1這樣的經典液環(huán)真空泵和壓縮機，而且它們還在世界各地的工廠運行。只有佶締納士制造的真正經典產品才100％經過性能測試且具有出廠保修。

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.
