2BE1 series water ring vacuum pumps and compressors

Download the brochure of 2BE1 series (pdf)

  The application range and characteristics:

  2BE1 series water ring vacuum pumps and compressors are the products with high efficiency and economic power, which are manufactured by our company integrating with the advanced technology of the imported products from Germany.

  These series products adopt single stage and single action structure and have many advantages, such as, compact structure, convenient maintenance, reliable running, high efficiency and economic power. Comparing with the SK, 2SK, SZ series water ring vacuum pumps used widely in our country at present, the 2BE series products are the ideal replacements of them for high vacuum, low power, and running reliability

 

  The main characteristics of 2BE3 series products:

  • .All the bearings are the imported products 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.
  • .The inner wall of the pump body is approximated by an ellipse to ensure the best pumping effect.

  Note: the above selected motor power in most conditions. Such as the outlet pressure is higher (0.02~0.05MPa), is should correspondingly increase the motor power; such as the normal work of 2BE1 vacuum pump shaft power is small, also can use close to the shaft power of the motor power, so more efficient.

  Note: water ring vacuum pump of the water temperature on the properties of the impact is larger, and the water ring vacuum pump performance curve were measured in 15 ℃ temperature conditions, so in the practical use of water ring vacuum pump coping water ring vacuum pump of the pumping speed is corrected. Correction method please refers to: water temperature of water ring vacuum pump performance.

Note:1.Types of the operating liquid: the water is used in the usual situation with standard temperature at 15oC (or its range is from 0oC to 65oC). Or at least the temperature is lower 10oC than the boiling-point.
  2.The data of the consumed volume of the water above indicate the data under the standard speed of the pump. Different pumps have different speeds. The practical value should multiply the ratio between the practical speed and the standard speed.
  3. If it is necessary to increase the flowrate of the operating liquid, the data in the above table should be twice.
