Main features:

1,The direct-coupled design is easy installation and save space.
2,The bearings are all the imported Japanes NSK
3, The standard configuration are all used the John Crane mechanical seals which can eliminate leakage and easy to maintain.
4,The pump has the cavitation protection port,when it works under the ultimate pressure, the cavitation protection port opens (or connects with the separator) in the case of ensure maximum suction effect to eliminate the noise of cavitation and protect the pump

5,2BV whole series standard configuration use the aluminum bronze impeller with high strength and raise its corrosion resistance and durable in use. If the parts of the liquid flows adopt stainless steel ,the pump will be work in more hard condition.
6, Special design of the exhaust port can avoid over-pressure and ensure the best efficient within the range of its performance.
