4 Comparative Cost of Pumps Material Ductile Iron GRP 316SS CD4MCu Alloy 20 Monel Nickel Titanium Hastelloy C Hastelloy B Zirconium Page 4

5 Comparative Cost of Pumps GRP Is: 70% the price of D4 (316SS) 30% the price of DC3 (Hastelloy C) 25% the price of TI (Titanium) Page 5

6 Advantages of Non-Metallics Excellent Corrosion Resistance Lower Lifetime Cost Extended Service Life Lower Maintenance Low Contamination Page 6

7 Advantages of Non-Metallics Hidden Benefits Lighter Weight Good Insulator No Painting Needed for Composites Non-Sparking No Galvanic Corrosion Reduced Noise Non-Magnetic Page 7

9 Impeller Semi-open Externally adjustable Compression molding yields inherently balanced impellers. Balance holes are not used. Pump out vanes and scallops achieve hydraulic balance Page 9

10 Impeller Since all impellers are compression molded and the sleeves are injection molded, we get very good mating surfaces. Page 10

11 Steel Industry Pickling Line Applications Waste Acid Recovery Aquariums / Zoo Filtration / Intake Applications Water Purification Industrial Waste Treatment Chemical Process Mining - Leaching Page 11

12 General Application Notes Generally limited to 300 ºF (149 ºC) Expansion Joints Required Faster reduction of strength with high temperature More susceptible to shock Process will heat up faster than with metals Page 12

13 Fybroc Series 1500 Horizontal ANSI Pumps Capacities to 5000 GPM Heads to 400 feet ANSI B73.1 Standard Pump Twenty Standard Sizes Page 13

14 Fybroc Weakness One piece shaft sleeve and impeller part for costly maintenance. You have to replace the impeller when you replace the sleeve. Resin Transfer Molding (RTM) process which utilizes cold molds, hand placement of fiberglass blanket, high labor content and chance of impurities and weakness. Snap rings instead of locking collar on bearings Page 14

15 Non-Metallic Lined Pumps Page 15

16 Applications Extreme Corrosives HF Acid Nitric Acid Sulfuric Acid NaOH Acetic Acid Phosphoric Acid Multipurpose Batch Operations Ultra pure liquid handling Page 16

17 Non-Metallic Pumps Pros: Lower initial cost Excellent corrosion resistance Less maintenance Lighter weight Good insulator Non-sparking Reduced noise No painting No galvanic corrosion Page 17

18 Non-Metallic Pumps Cons: Temperature (300 o F max) Solids Strength vs Temperature Need for expansion joints Shock susceptibility Heat retention Page 18
