2BV water ring vacuum pump

Description

2BV series water ring vacuum pump is a single stage pump with integral structure and coaxial pump.  Shaft seal adopts mechanical seal, with the characteristics of simple structure, simple installation, oil free, safe and reliable.  The pump is designed to remove gas and wet steam, and the suction pressure can reach 33mbar absolute pressure (97% vacuum).  Widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields.

2BV series water ring vacuum pump possess the characteristics as bellow:

1. The close-coupled design is convenient to install and can save space;

2. The standard seals are all used the John Crane mechanical seals;

3. 2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump;

4. Aluminum bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel, the pumps can be used under the more rigorous condition;

5. The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the pump;

6. The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F;

7. The bearings are all used the imported products with brand name of NTN or NSK.
