10. Standard Gauge Tappings
All casings / volutes are tapped for gauge installation

11. Centerline Discharge All Taco FI volutes are centerline discharge
Centerline geometry does not trap air
Piping Load
Competition uses overhanging tangential discharge
Centerline discharge evenly distributes the piping loads to the base
Overhanging tangential discharge volutes are less desirable because they incur both bending & torsion stresses

12. Foot Mounted Volutes
Piping Load
Better suited to support inevitable piping loads associated with improper installation
Taco foot mounted volutes with feet positioned directly below the pipe flange provide better support
Foot

13. Lost Foam Impellers Tools are made of aluminum
No tool wear when injecting foam
Each piece is dimensionally identical

14. Foam impellers prior to casting

15. Lost Foam Process
Dip foam in clay slurry…
….and let dry

16. Lost Foam Impellers Lost foam is precision investment casting process
Foam is vaporized and replaced by molten bronze

17. Lost Foam Impellers Advantages:
Superior surface quality creating smoother passageways
Higher efficiencies & hydraulic performance
Repeatability
No tooling wear

18. Sand Cast Impellers Competitors use a sand casting process
Over time, sand packing abrades and degrades patterns
“This is like making a copy of a copy of a copy indefinitely.”

36. Forsheda Seals All bearing frames come standard with Forsheda seals
Protects the bearings from external moisture and airborne contaminants.
None of the competitors do this.

37. Pump Couplings Woods Dura-Flex Couplings standard Competitor
Ideal for all applications
Superior for variable speed applications
Competitor
Not desirable for all applications
In variable speed applications, constant loading & unloading of coupling causes rubber insert to vibrate & wear, resulting in premature failure

38. Taco Design Philosophy
Minimize the need to EVER service the pump
Resulting in a minimum number of seals and bearings throughout the entire product line
Owners spend significantly less maintenance dollars
Owners use less storage space

39. B&G Philosophy
What happens when you don’t use a minimum number of seals and bearings?
Requires owner to stock MORE replacement parts
Requires more space
Increases storage costs

40. Taco pumps require minimal replacement parts
Taco Parts Philosophy
Taco pumps require minimal replacement parts
These gaskets, seals & bearings cover the entire line of Taco pumps!!

41. Pump Maintenance Issues
Overview of Industry
Pump Maintenance Issues
Majority of pump UNITS shipped are smaller inline pumps
Overall, our industry does not offer the end user a robust, simple inline pump
Majority of maintenance hours are spent on smaller pumps
Majority of maintenance dollars are spent on larger pumps
Most manufacturers want to maximize their profit opportunity on the installed base of their products (All pumps, small to large)
They try to do this in 2 ways:
Use a design that inherently requires service
Use a part numbering system that implies you need a unique new part # (SKU) for each model of pump you own
Taco’s entire product line addresses ALL of these points
i.e & 00 offering vs. B&G Series 60
