2BEC Series of Water Ring Vacuum Pumps and Compressors

Applications and features

2BEC series of water ring vacuum pumps and compressors are high-efficiency and energy-saving products on basis of our many years research results and experiences in production and combine with the advanced technique of the like products, which represents the latest technique of pump industry with efficiency raised by 10-30% and energy saving of 20%. It is usually used to pump gases that are non-corrosive, insoluble in water, no solid particle contained by forming vacuum and pressure. With the structure and materials changed, it’s also used in pumping corrosive gas and acclimatized to corrosive working fluid. These products can meet the needs of such industries as pulp and paper, chemical process, petrochemical, light industry, pharmacy, foods, metallurgy, building materials, electrical appliance, coal cleaning, mineral concentration, fertilizer, etc.

This series of pumps take the structure of single stage and single function with features of simple structure, convenient maintenance, reliable running, high efficiency, and energy-saving. It can adapt to the serious working conditions such as a big water discharge and load fluctuation, etc.

The key parts as distributing plate, impeller, and pump shaft are improved design in order to realize simplified structure, better performance, and more energy-saving; welded impeller and primary punched blade are adopted with rational mounded lines; all hubs are completely machined so that the issue of dynamic balance is solved fundamentally; impeller and pump shaft are machined by heat-assemble and interference fit with reliable performance, stable running; the whole impeller is well heat-treated after welding; the excellent tenacity of blade ensures the capability of impact resistance and bending resistance so that meets the needs of serious working conditions of load fluctuation.

2BEC series of pumps have gas and water separator provided for it, and there are discharge ports setting in several position and cover for inspection port in pump casing. The clearance between impeller and distributing plate is adjusted by locating two bearing ends cap. It is convenient for installation and application as well as operation and maintenance.

Our vacuum pumps are strictly inspected and tested by testing and inspection center, whose performance is superior, reliable and durable.
