Description: EDUCTOR PRINCIPLES: BEX eductors use a unique venturi design which enables smaller pumps to circulate large volumes of tank solution. The eductor will circulate four to five gallons of solution for each gallon pumped. BEX eductors are used for mixing chemicals, suspending solids, adjusting pH,
Standards and Technical Documents - Vapour vacuum pumps -- Measurement of performance characteristics -- Part 2: Measurement of critical backing pressure -- ISO 1608-2:1989
Description: The considered method of measurement deals with vapours jet vacuum pumps, diffusions pumps and diffusion-ejector pumps. The dependence of the performance of these pumps on the backing pressure can only be completely described be means of a curve relating the inlet and backing pressure over

BEX Spray Nozzles
EDUCTOR PRINCIPLES: BEX eductors use a unique venturi design which enables smaller pumps to circulate large volumes of tank solution. The eductor will circulate four to five gallons of solution for each gallon pumped. BEX eductors are used for mixing chemicals, suspending solids, adjusting pH, "sweeping" debris or sludge toward a filter intake and many other useful applications. TYPICAL APPLICATIONS: - Plating tanks. - Cleaning tanks. - Phosphating tanks. - E-coat tanks. - Fertilizer tanks... (read more)

Water Jet Eductor...liquid pumping and mixing
Principle of Operation. Schutte & Koerting - Water Jet Eductors are designed for liquid pumping and mixing operations and for the handling of some solids. In operation, pressure liquid enters the eductor through the pressure nozzle and produces a high velocity jet. This jet action creates a vacuum in the line which causes the suction liquid to flow up into the body of the eductor where it is entrained by the pressure liquid. Both liquids are thoroughly mixed in the throat of the eductor... (read more)

Steam Ejector Pumps And Ejectors & Steam Ejector Theory
by a properly designed throat or venturi will economically make use of high pressure fluid to compress from a low pressure region to a higher pressure. This change from pressure head to velocity head is the basis of the jet vacuum principle. Ejectors are generally categorized into one of four basic types
