Smth Pump Company THE SMITH PRIMER Volume 1, Issue 18 December, 2008 To the company employees, our customers, our vendors, and our friends, I wish you a merry Christmas and a happy New Year! Inside this issue: Big Picture Stuff 1 Vendor News 4 Project Calendar 1 Big Picture Stuff by L. G. Smith, p.e.-President/C.E.O. My last article was about our new computer software system, and this article continues that discussion. We were excited last May to be finally working on implementation of Microsoft Dynamics AX. There were six months of preparation, and then the big day came. Go LIVE was November 1, 2008. We came to work on Monday, November 3rd, and said “Now what!?” Things didn’t go as smooth as I would hope, but most of the issues would have been difficult to resolve prior to Go LIVE anyway. Even with all of the training most of us have struggled to change the way in which we did things for the past 10 or 12 years. Project Calendar by Jean Radtke Kempner Water Supply Corporation recently awarded a contract to Matous Construction of Temple, Texas for a 7 million gallon per day water treatment plant and raw water intake. Smith Pump Company was awarded the pumping equipment portion of that contract and will be supplying the raw water intake pumps and motors, suc- tion barrels, intake structure, screens and discharge column pipe. At the new water plant, Smith will supply the high service Continued on page 3 Employee of the Quarter 2 Calendar of Events 1 Hydraulic Primer 2 Points to Ponder 7 Employee News 7 Continued on Page 3 Calendar of Events Dec. 22– Dec. 24th Skeleton Crew Dec. 25th & Jan. 1st–Merry Christmas and Happy New Year SPCO Holiday Dec. 26th, 31st & Jan. 2nd– Skeleton Crew Feb. 3-5 Texas Water Utilities Assoc.

THE SMITH PRIMER Page 2 Smth Pump Company “Chris has been employed at Smith Pump since 1992. He has a B.A. degree in Business Administration from Baylor University, and played the offensive center position on their football team. He is one of the smartest guys I know (for a football guy), and can always figure out why an account won’t balance or a computer won’t cooperate. Chris wins the Employee Of The Quarter process because of the effort he has put into the implementation of Smith Pump’s new software system, Microsoft Dynamics AX. Since March, Chris has been performing his regular jobs (yes jobs, Accting Mgr & IT Mgr) and preparing for implementation of our new software. There have been untold man-hours spent in software setup and data transfer. We went LIVE with AX on November 1st, 2008. Even with six months of preparation there was one crisis after another that required Chris’ attention. In fact at this writing, Chris remains in full implementation mode. Our “Employee Of The Quarter” is Chris George. Chris is the head of Accounting, and is the I.T. (Information Technology) Manager. He is based in Waco. Chris’s supervisor, Granger Smith (that is me) had this to say about Chris… Hydraulic Primer By Clinton Tabor I know the last months have been tough. There is a light in the tunnel ahead, and it is not the light on the front of the engine. Please thank your wife Elaine for allowing you the time you’ve spent on this project. I am sure you could use the extra day off, but please finish implementa- tion of AX first. Basically, pumps work because they create a pressure differential in the liquid stream. Vertical turbine pumps create a significant pressure differential between the suction side and discharge side of the impeller which results in a hydraulic down force or axial thrust along the shaft. The pump manufacturers typically provide a hydraulic thrust factor, Kt, which has the units of pounds of force per foot (lbf / ft) for each pump model. The Kt value may be 1-2 for small pumps to several hundreds for large pumps. This value multiplied by the total discharge head of the bowl assembly and the specific gravity of the fluid results in the total hydraulic axial force. F = H (head) * Kt factor * Specific Gravity (Specific Gravity = 1.0 for water) The value is important for several reasons. First, this value added to the weight of the line shaft, line shaft couplings, motor coupling (if applicable), impeller weights and pump shaft weight provides the total down force that the motor bearings must withstand during operation. The down force may be calculated at the design operating condition for bearing life calculations and at the shutoff condition for maximum expected force on the bearings. Secondly, the axial thrust causes the line shaft to elongate. This elongation is normally ignored in pumps with settings less than 50 feet. However, in deep set pumps, shaft elongation becomes a significant concern. The formula for calculating shaft elongation is: e = F * L / (E * A) (in inches) where F = the axial force (shown above) L = the total shaft length (in inches) E = Modulus of Elasticity (~29,000,000) and A = area of the shaft (in Inches) Let’s assume that the application requires a pump setting of 500 feet, with a design condition of 350 gpm at 600’ TDH. I selected a 16 stage Fairbanks Morse 10A bowl assembly with a Kt of 3.4 lbf/ ft. (continued on page4) Continued on page 4 Volume 1, Issue 18 Big Picture Stuff . . . continued from page 1 To make matters worse, we changed our part numbering system concurrently with this Go LIVE date. So, while struggling with the right keystroke sequence, we did so with inventory numbers for parts and pumps we didn’t recognize. I can sum up the experience by saying it was like starting work for a new company with a bunch of people you knew well. The only good was that all of us struggled. Some struggled more than others.

At this writing, we are working through our shop communication problem, but this issue reminded me of simpler times. In the old days, we were not so formal. In those simple days, some of our customers were in a big hurry like they are today. So if there wasn’t time to sit down at the drafting board and spend three days making a drawing, the draftsman would walk down to the shop, and together with the foreman, they would make a chalk drawing on the concrete floor. Often these drawings were made to full scale with chalk lines and squares. If a dimension was needed, you used a tape measure on the drawing. Typically a top view and profile view were drawn. We built very good products in those days just like we do today. The cycle time from order to ship was extremely short. However, long term records suffered when it was time to erase the floor and start on the The high service pumps at the water plant are Fairbanks Morse 17M 4-stage vertical turbine bowl assemnext project.

This project was a team effort between the Austin Page 4 THE SMITH PRIMER Smth Pump Company Vendor News Aurora Pump - 90 Years of Quality, Patriotism and Humanism by Libby Wilson With the great war behind them and the roaring twenties ahead, a few young engineers began a new company in 1919 that would grow to over 130 million in sales along with her sister companies before the ringing in of the 21st century. The first product line developed was the single cylinder, double plunger, deep well reciprocating pump line. A short time later the vertical deep well turbine line and side suction horizontal centrifugal pump lines were developed. An expansion into horizontal centrifugal pumps followed. The principal market for Aurora Pump during the early days was irrigation for the agricultural industry as the nation began to rebuild the land. After the Depression, the deep well turbine was phased out and Aurora Pump began its journey to become one of the leaders in the horizontal centrifugal and turbine vane pump market. New industries, trade, and marine services sparked new pump designs. In the 40’s, Aurora supplied large numbers of pumps for navy vessels and the handling of fuel for the Air Force. Due to their great efforts during the war, Aurora Pump received the Hydraulic Primer ... continued from page 2 The axial force is 3.4 lbf/ft X 600 ft = 2040 lbf. The expected elongation of a 1” shaft is: e = (2040 X 500 x 12) / (29,000,000 X 0.785) = 0.538 inches At the shutoff condition of 836 ft, the axial force is 3.4 X 836 = 2842 lbf and the expected elongation of a 1” shaft is: “Army Navy E” three times, a highly coveted award extended to manufacturing plants and organizations which showed excellence in products supplied in partnership with the mighty fighting forces of this nation in their bid for victory after Pearl Harbor. As the 60’s rolled in, Aurora sought out new markets, developing the AVS (or ANSI) chemical pump to grab a share of the growing chemical industry. Also during this time a need for silent submarine running arose, therefore, Aurora responded with the reactor plant fresh water pump. These pumps had to perform undetected, therefore, extensive sound and vibration testing was required. This period of growth for Aurora sparked a need to build the facility they inhabit today: a 52acre site in North Aurora, Illinois where they continue to improve pump efficiency, production methods and advance their product lines into the high-tech world in which we live today. Aurora Pump qualifies for the ISO 9000 designation. Quality, patriotism and humanism have always been a part of Aurora Pump. Factory holiday closings may be a factor for many of our customers this month. As the closings may vary somewhat, please keep in mind that there may not be any shipments going out for a week or more. Please get your orders in early. For those unfortunate situations where a part replacement arises quickly, some of the factories offer an emergency ship program during the holiday season . These programs of course are offered at a premium. Smith Pump will have a skeleton crew in each office across the state from the 22nd – 24th, 26th, 31st and January 2nd. MERRY CHRISTMAS AND SAFE TRAVELS. The weight of the line shaft, couplings, impeller weight and bowl shaft adds down force to this application, but this is not considered in the shaft elongation calculation because it is constant between the static condition and the operating conditions. If the line shaft diameter is increased to reduce elongation, the total down force to the motor bearings is increased because of the added material weight. e = (2842 X 500 x 12) / (29,000,000 X 0.785) = 0.749 inches The expected elongation of a 1-1/2” shaft at the design point and shutoff are 0.23 inches and 0.33 inches, respectively. So why do we care if the shaft stretches ½ to ¾ of an inch over the 500 feet of shaft? The impellers are “set” to operate at a particular location within the bowl to provide best performance. As this shaft stretches, we must insure that the impellers are at the optimum location and that they will not interfere with the bowl casing over their full range of travel. Bowls are designed with “lateral” to allow some vertical movement of the impeller without dramatically influencing performance. The performance of bowls with enclosed impellers is less affected by vertical movement of the impeller with relation to the bowls than open impellers. So as the line shaft diameter is sized to handle the required horsepower of the application, on deeper set pumps, the shaft elongation must be calculated to ensure the impeller can be set for optimum performance. Changes in shaft material will have more influence on the horsepower or torque carrying capability than on the elongation. Yield strength for typical line shaft material varies from 40,000 psi to over 100,000 psi whereas the Modulus of Elasticity for most steels ranges from 28,000,000 psi to 30,000,000 psi. Higher strength steels reduce the shaft diameter required for the torque and increase the elongation because of the smaller shaft diameter. Page 5 Volume 1, Issue 18 Families Neighbors by Karol Smith We continue to pray for Bridgette and her family. Here is a picture of Bridgette and her children, daughter, Baylee, 8 years old and sons, Koby five, and Kelby, two . Many thanks to our extended family at Fairbanks Morse for their kind donation to Bridgette Hollingsworth. Bridgette is the daughter of Neal McCaig, our Fab shop supervisor (Waco) and is courageously battling cancer and harsh chemo treatments. A very generous donation was made by Fairbanks Morse through a grant from their benevolence fund. Fairbanks in Kansas City has about 300 associates but has managed to maintain a family atmosphere. They have a contribution committee that is made up of seven shop and office employees that have two primary tasks. They are responsible for determining which local charities they recommend to the Pentair Foundation for funding and they administer a local benevolence fund that is typically used to help employees in distress. This year they issued two grants from their benevolence fund and one went to Bridgette. On behalf of the Smith Pump family to our family at Fairbanks Morse we would like to offer our most sincere gratitude. Lance Mize, son of Darrel (Austin) and Belynda Mize, and wife, Jennifer, had an early Christmas present. Jayden Lance Mize, was born on August 27, 2008, weighing in at 7lb.5oz.. This picture was taken at the Waco airport on October 16th when Lance met his son for the first time. The pilot held the passengers on board to let Lance off the plane first. Lance was home for three weeks to get to know his new son . He is a member of the US Army stationed at Fort Hood. His unit is scheduled to be back home from Iraq in mid March. His unit is Straight Arrows Alpha (A) Battery 4-42 Field Artillery. His unit is currently deployed to central Baghdad at Camp Prosperity Iraq. Please keep Lance and his family in your prayers and all of our soldiers for a safe return home. Congratulations! Thomas Granger Smith, II, son of Granger (President/CEO) and Lisa Smith, graduated from Oklahoma University on December 12th with a Bachelor of Journalism, degree in Advertising. Way to go Thomas! Josh Jurgensen, (Waco) and wife, Julia, are expecting their first child in June. Brandi Browder, daughter of Chris Browder, (Waco) will marry Trenton Armstrong on January 10th. Trenton Brown, (Waco) will graduate from Baylor University on December 20th with a Bachelor of Science degree in Mechanical Engineering and will begin his career with Smith Pump Company on January 5th.
