Nash 2BV2 Liquid Ring Vacuum Pump newly launched explosion-proof motor series

The 2BV2 liquid ring pump with coaxial direct connection design is a high-power and multi-functional pump, which can save working fluid by up to 50%. 2BV2 liquid ring vacuum pump / compressor has longer service life and adopts stainless steel shaft to improve corrosion resistance. The pump body can be made of all stainless steel, can be equipped with ordinary motor or explosion-proof motor, and can also have different material combinations to meet various process applications.

The excellent performance and reliability of Nash liquid ring vacuum pump has been verified for more than 100 years. It plays an indispensable role in various industrial application fields and can meet the application requirements of more severe working conditions. Nash vacuum pump has well-known reliability, which is higher than the standard design of general industry.

The 2BV2 liquid ring pump with coaxial direct connection design is a high-power and multi-functional pump, which can save working fluid by up to 50%. 2BV2 liquid ring vacuum pump / compressor has longer service life and adopts stainless steel shaft to improve corrosion resistance. It can work safely and reliably even under extreme conditions (such as wet process). The pump body can be made of all stainless steel, can be equipped with ordinary motor or explosion-proof motor, and can also have different material combinations, such as stainless steel, bronze, ceramics, cast iron and ceramic coating. This allows them to be customized according to the corresponding process requirements, so as to resist erosion and corrosion for a long time.
