Water Ring Vacuum Pump / Liquid Ring Vacuum Pump (2BE4)

The 2BE4 vacuum pump produced by Greentech International (Zhangqiu) Co., Ltd was developed from the proven NASH 2BE3 pumps, whose reliable performance has been further improved..

The footprint and connections to the NASH 2BE4 models are identical to its predecessors, the NASH 2BE3 pump. Therefore, exchanging or upgrading to the more efficient NASH 2BE3 requires no site modifications.

The NASH 2BE4 model is available in cast iron, with stainless steel coming soon. The 2BE4 is perfect for use in mining, filter applications, paper mills, power plants, chemical plants, refineries and more

The main characteristics of 2BE4 series products:

All the bearings are the imported products with the brand name of NSK orNTN for ensuring the precise orientation and the high stability during the working of the pump.

The material of the impeller is QT400 nodular iron or stainless steel for ensuring the stability when the pump works under the rigorous condition and can extend the lifetime of the pump.

The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE1 series pumps.

The shaft bushing is made of stainless steel to improve the lifetime of the pump 5 times than the normal material.

The V-belt pulley (when the pump is driven by the belt) is used the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.

The coupling is used to drive the pump directly. The flexible part connecting the two half coupling is made of polyurethane that makes the pump more reliable.

The unique design to set the separator above the pump saves the space and decreases the noise efficiently.

All the parts are cast by the resin sands that make the pump surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.

The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.
