Peerless Pump Company, LLC MSLA & MSMR Multistage Pump Selection SECTION 2920 Page 1 1. Select basic Pump size based on Hydraulics. (Use RAPID Version 6.2) 2. Review suction pressure 3. Look at Shut-Off pressure 4. Look at temperature 5. Then go to P/T selection Chart (Graph on Page 3) 6. Choose Impeller Material 7. Then Find Pump Construction Code (0X, 0R, etc.) 8. Select seal arrangement (pack, seal, etc.) 9. Find Pump Construction Code (001, BK3, ABC, etc.) 10. Select Flange Rating and Orientation 11. Find Pump Construction Code (AB, CB, EE, etc.) Example: PUMP IDENTIFICATION CODE CONSISTS OF 20 ALPHA-NUMERIC CHARACTERS EXPECT DELAYS IN ORDER ENTRY WITHOUT COMPLETE CODE MSL A 050 08 9 B A BK3 OS P AB Flange Position & Flange Design (250 Lb Axial Suction & Vertical Discharge) Casing Seal (Buna-N) Material of Construction (Bronze Impellers ) Shaft Seal (Burgmann Mechanical Seal ) Suction Bearing (Product Lubed ) Pump Hydraulics Impellers trimmed to Job Conditions Number of Stages Pump Model Construction Level Series (400 Psig and lower) Casing Seals Data Buna ( P ) and EDPM ( E ) are the Standard Casing O-Ring Materials. Viton fluoroelastomer ( V ) is provided as a special version <180 0 C. (356 0 F.) Buna is good for temperatures <110 0 C. (230 0 F.) EDPM is used for temperatures <200 0 C. (392 0 F.) EDPM is not resistant to mineral oils or other hydrocarbon liquids. Viton should be used for hydrocarbon liquids. Mechanical Seals All listed mechanical seals are furnished with EDPM Elastomers suitable for hot water, diluted acids and hardly inflammable hydraulic liquids. Refer to the factory for hydrocarbon liquids. Viton is a registered trademark of DuPont Dow Elastomers
