2BV series liquid ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree). So the liquid ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump.

2BV series liquid ring vacuum pumps and compressors will replace the SK and 2SK series liquid ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.

If the pump is connected with Ex-proof motor, it can be used for pumping the explosive gases or work in the flammable and explosive environment.

2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.

According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing,pump cover, port plate, impeller)are made of various stainless steel as bellow:

  • SUS304(0Cr18Ni9)

  • SUS316(0Cr17Ni12Mo2)

  • SUS316L(00Cr17Ni14Mo2)

  • The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti

  • The close-coupled design is convenient to install and can save space.
  • 2BV series liquid ring vacuum pumpproducts 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.
  • Aluminium 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 more rigorous condition.
  • 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.
  • The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.
  • The bearings are all used the imported products with brand name of NTN or NSK.

Common failures of self-priming pumps

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.

Classification and difference of submersible pumps

The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
