Application scope and charateristics:

2BE1 series water ring vacuum pumps and compressors are the products with high efficiency and economical 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 economical 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 charateristics of 2BE3 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 drived 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 mechnical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.

The photos of the spare parts: the impeller made of Nodular QT400, the pump cover made of cast iron, the pump casing made of carbon steel, the port plate made of cast iron, the mormal bare pumps being tested,
the impeller made of stainless steel, the pump cover made of stainless steel, the port plate made of stainless steel.

Notes:
1."D" means "Direct drive"; "V" means "V-Belt drive".
2.The motor recommended above can work under most conditions. If the discharge pressure exceeds the scope of 0.02~0.05 Mpa(G), it is necessary to increase the motor power. If the shaft power corresponding with the work pressure of the 2BE series vacuum pump is lower (refer to the curve of the shaft power), the motor with lower power closed to the shaft power can be used for saving energy.

Notes:
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.
