1 SER-DUCTOR PUMPED AGITATION 89 A-07G Efficient agitation and mixing of: CLEANING / RINSING / PLATING / WASTE TREATMENT and OTHER PROCESS SOLUTIONS A SER-DUCTOR system provides solution agitation with a centrifugal pump by drawing liquid from a tank and returning it to the tank through a sparger system, similar to that used for air agitation, with eductors strategically placed along the sparger pipe. SER-DUCTOR agitation delivers times the pump output at each nozzle.it effectively distributes the desired level of agitation to critical areas in your process tank. The system is driven by your choice of vertical, magnetic drive, self-priming or mechanical seal pump. With SER-DUCTOR systems, solutions are agitated without the introduction of foreign matter such as airborne dirt or compressor oil, as is often the case with air agitation. Whether the solution is a cleaner, a rinse, a plating bath or other process solution, it is only this fluid that is recirculated by the SER-DUCTOR system. SER-DUCTOR agitation in a process tank keeps particulate from settling to the tank bottom where it can form a layer of sludge that shortens the life of the solution, requires expensive dumps, new make-ups and costly downtime in between for manual cleanout of the tank bottom. By effectively keeping the "dirt" in suspension, the SER-DUCTOR system makes it easier for a filtration system on the tank to remove particles. This extends the life of the bath and greatly reduces the possibility of contamination being carried to other tanks in the process cycle where it can lead to costly rejects and even product failure. PROVEN BENEFITS OF SER-DUCTOR SYSTEMS IN PLATING APPLICATIONS Reduces airborne fume emissions by 90% Saves heating costs up to % Reduces brightener consumption 0% Saves metal as a result of more uniform brightness and thickness distribution Improves throw and deposit thickness in blind and through holes and recesses Permits increased current density, especially compared to air or cathode rod agitation, for faster plating rate Reduces carbonates in alkaline processes Reduces or eliminates gas-pitting Provides constant agitation because SER-DUCTOR systems don't clog

2 90 SER-DUCTOR AGITATION SYSTEMS APPLICATIONS A-07G PRINCIPLE OF OPERATION Liquid pumped into the eductor nozzle exits at high velocity, drawing an additional flow of the surrounding solution through the eductor. This additional flow (induced liquid) mixes with the pumped solution and multiplies its volume five-fold. The source of the pumped liquid (input) can be a pump or filter chamber discharge. NOZZLE INPUT EACH GALLON OF PRESSURE LIQUID INDUCES FOUR GALLONS DIFFUSER OUTPUT FIVE GALLONS RECIRCULATED OF LIQUID TYPICAL APPLICATIONS For printed circuit boards and rack plating SER-DUCTOR agitation in printed circuit board manufacturing and rack plating applications enhances plating solution flow across the board surface. Carefully engineered clusters of eductor nozzles sweep away cathode films swiftly, allowing faster plating at lower voltages with much higher current densities. More even plating and significantly lower metal usage result. (The horizontal direction of eductors stationed along vertical distributor pipes is a typical SER-DUCTOR configuration for these applications.) For parts cleaning in baskets or on racks SER-DUCTOR agitation for bulk parts cleaning in baskets or for racked work improves solution flow through the work and assures greater impingement of fresh solution on the parts. Additionally, in cleaner tank applications, SER-DUCTOR agitation prevents temperature stratification. It also keeps solids in suspension so they can be more easily removed by filtration. This extends bath life and reduces chemical makeup costs. (The moderately upward angle of these eductors along "wishbone" distributor piping provides the proper direction of solution flow.) For mixing Vigorous SER-DUCTOR agitation within the tank creates sufficient solution movement to eliminate solution strati-fication. This movement lends itself to mixing two or more liquids or to mixing a liquid and a powder. (A more extreme angle of eductor positioning is helpful in mixing bath components and assuring continuing uniformity of the solution.)

NOTE: When the tank height is greater than ¼ times the tank diameter, dual propellers should be used to assure complete mixing. The second propeller is generally located midway between the bottom propeller and the liquid surface. See Technical Bulletin TA-0 for selection guidelines.

7 9 MIXER SELECTION GUIDELINES A-0H SELECTION GUIDELINES The following guidelines and selection tables are based on mixing in vertical cylindrical tanks with flat, dished or shallow cone bottoms. Mixer selections may vary with tank shape, retention times, starting conditions, etc. For liquid levels. to. times the tank diameter, a single propeller is suitable. A single propeller may be located from. to.0 propeller diameters off the tank bottom. The optimum distance is one() diameter off the bottom. (Example: 0 diameter prop, should be approximately 0 off the tank bottom) For liquid levels. to times the tank diameter, dual propellers are recommended. When dual propellers are required, spacing between gear-driven mixer propellers should be approximately two () propeller diameters: propeller spacing for direct-drive mixers should be to propeller diameters. The mixer position in an unbaffled tank should be as shown for maximum turnover of liquid and optimum mixing. Positioning the propeller on center will produce a vortex which may help in wetting and dispersing light solids. Mixer position in square and rectangular tanks is similar to cylindrical tanks. When L is more than x W, consult your SERFILCO representative. to d SPACING D x d to 0 H Proper matching of propeller and motor is usually based on the turnover, or pumping rate, for the application. (Polymer mixing is an exception.) Pumping rate is arrived at by the following: Q=N Q N d³ SELECTION TABLES Two or More Liquids (Blending) PRODUCT VOLUME (GALLONS) VISCOSITY Up to 00 cps 0-70 cps cps cps 000 cps Shear Sensitive (Polymers) TANK VOLUME GALLONS WHERE: Q = pumping rate in gallons per minute N = mixer speed in RPM d = propeller diameter in inches N Q = pumping coefficient for propeller type (.0 or square pitch marine propeller, N Q =.) standard (. steep pitch marine propeller, N Q =.77) optional PERCENT SOLIDS BY WEIGHT - 0% - 0% - 0% 0-7% (Ceramic slip) SMD SMD SMG SMG SMG SMD SMD SMD0 SMG 0 SMD SMD SMG SMG SMG0 SMD SMD0 SMG0 SMG0 SMG0 SMGV Liquid - Solids/Slurries 7-00 SMD SMD7 SMD00 SMG0 SMD SMD7 SMG0 SMG7 SMG0V WASTE FLOW RATE (GPM) SMD SMD SMD0 SMG SMG0 SMG7 SMD7 SMG SMG00 SMG00 SMG00V VOLUME (GALLONS) SMD0 SMD00 SMG0 SMG00 SMD00 SMD00 SMG00 SMG0 0 SMD SMD SMD00 SMG SMG0 SMG00 SMG SMG7 SMG0 SMG00 SMG0V SMG SMG0 SMG7 SMG0 SMG SMG7.
