The New Bearing Gard TM Customer Presentation
Agenda Welcome to the Bearing Gard • Introduction • Product overview • Design qualification • Same Day shipment • Support materials 2
Why use a Bearing Gard? Extend rotating equipment life and improve reliability with the Bearing Gard • Prevent contamination ingress – Extend oil and bearing life – Eliminate #1 cause of rotating equipment failure • Provide long term oil retention – Reduce bearing and lube operating temperature – Extend bearing and lubrication life – Improved housekeeping and safety • Added protection at shutdown – Shut-off O-ring blocks air transfer • Create a positive return on investment – An average investment of $400 per pump or motor can prevent maintenance or repair costs of $5,000 - $20,000 and more 3
Where do I use the Bearing Gard? General bearing seal replacement (lip or labyrinth) in: • All types of non-flooded bearing seals in rotating equipment • Pumps: ANSI, ISO, API 610 and more • Electric motors: IEEE-841, severe duty, washdown and more • Gearboxes: non-flooded oil lubrication and grease 4
The Bearing Gard Completely Redesigned for World Class Performance • Technical Performance – Superior contamination exclusion – Includes static ‘shut - off’ technology – Excellent oil retention – Easy installation • Delivery Performance – Automated design process – Built for industry-driven quick shipments – Including “Same - Day” shipment for unique sizes 5
Bearing Gard Qualification Testing Performance validated from 22 to 150 mm (.875 to 6.000 inches) • No contact, wear or heat generation from 0 - 3600 rpm • Confirmed to hold static vacuum • Oil retention for standard and overfill situations from 0 - 3600 rpm • High velocity water spray performance 6
Bearing Gard Validation Testing High velocity water spray test simulates extreme conditions High Velocity Low Velocity 7
Bearing Gard General Design 1 3 2 Every aspect has been optimized 1. Pressfit in housing 2. Stator O-ring 6 3. Protected interface 4. Contamination channel 8 5. Contamination outlet 7 6. Unique dual drive O-ring 7. Innovative static shut-off barrier 4 9 8. Oil collection chamber 9. Protected oil outlet 10. Improved unitization 10 5 8
Key Features Unitization with axial runout Improved unitization feature • Prevents shut-off O-ring binding • • Axial runout up to 0.63 mm (0.025 in) Exceeds competition’s standard axial • runout of 0.13 mm (0.005 in) 9
Key Features Innovative shut-off design Improved static sealing • • Tapered shoulder creates positive side wall sealing at all times • Dynamically lifts off to prevent wear at operational speed Increased reliability by preventing O- • ring binding RPM 10
Bearing Gard A more reliable solution • Older design issues start at axial runout of 0.17mm(.007 in) Rotor • Minor binding with heat / wear • Major binding causes catastrophic drive o-ring failure • Extreme binding causes shaft damage and extreme heat Stator 11
Key Features Unique double drive ring Superior shaft grip • Improved rotor stability • • Compact size 12
Key Features Installation alignment notch • Located at the 12 o’clock position • 180 degrees from outlet ports • Customer requested feature • Not present on Inpro designs • Helps orientation for installation • Easy check for proper assembly 13
Key Features Part Marking now standard • “Flowserve” • Part number • Engraved on rotor OD (quick shipment) • Optional Laser on rotor face (high volume) 14

Bearing Gard Core Design Core design easily retrofits where standard competitive designs were used 16
Bearing Gard Core Design Ten questions to determine if the Bearing Gard ‘Core’ design is OK to use: 1. Is Shaft Diameter 0.875" - 8.000" (23 - 203 mm)? 2. Is Cross Section (Housing Bore - Shaft OD) 0.75" - 2.000" (20 - 50 mm) for shaft sizes up to 6.000 inch (152 mm) or 1.00” - 2.00” (25 - 50 mm) for shaft sizes greater than 6.000 inch (152 mm)? Is Insertion of 0.325" (8.3 mm) for Housing Bore up to 5.375” (136 mm ) or 0.375" 3. (9.5 mm) for Housing Bore over 5.375” (136 mm) OK? 4. Is Protrusion of 0.375" (9.6 mm) OK? 5. Is the axial movement 0.025 inch (0.63 mm) or less? 6. Is the radial shaft Movement 0.005 inch or less (0.13 mm)? 7. Is the Shaft Speed less than 100 ft/s (30m/s)? 8. Is the oil Lubrication not flooded (oil level below shaft)? Is the shaft Temperature less than 375 ° F (190 ° C)? 9. 10. Are the Materials bronze and Viton? • If yes to all, the core design is OK to use • If no to any, contact Flowserve for an “Engineered” solution 17
