1. Brushless, Seal-less Booster Pumps Reduce Total Cost of Ownership

2. YOU CAN! “The windows on the bus are foggy and the kids are cold!”
Wouldn’t it be nice if you could completely eliminate this recurring problem?
YOU CAN!

3. Brushless, Seal-less Technology Lasts a Lifetime!
Brushless, Seal-less, Coolant Booster Pumps specifically designed for the school bus market increase reliability and minimize TCO
How Does it Work?

4. Brushless Motors Live Long and Prosper!
Brush-based Motor
Commutates by electronically switching stator fields through rotor position sensing
Highly Efficient Performance
No maintenance required
Up to 40,000 hour life available in school bus applications
Commutates by carbon brush and rotating copper connection
Inefficient Performance
Requires Maintenance
1,000-1,500 hour typical life in school bus applications

5. Magnetic Coupling Eliminates Leaks
Magnetically coupled seal-less pump eliminates leaks
Static containment shell forms a liquid pressure boundary
Mechanical seals lubricate and cool themselves by “leaking” fluid into the operating environment
Seals quickly wear down causing excessive leakage and pump failure

6. Pump Technology Comparison
Brush-based SEALED Pump
Brushless, SEAL-LESS Pump
Brush Motor
Commutates (switching magnetic fields) by carbon brush and rotating copper commutator connection
Requires Maintenance
1500 Typical Life
Sealed Pump
Utilizes a rotating contact seal on fixed carbon face that inherently leaks
Warranty
Typically 1 Year
Cost
Typically $160 to $250
Needs to be replaced as often as every 6 months or up to every 2 years depending on application
If average bus life is 12 years, you could need at least 6 pumps at a cost of $960 (+ replacement labor)
Brushless Motor
Commutates electronically switching stator fields through rotor position sensing- no wearing contacting electrical connections
No Maintenance
Up to 40,000 Hour Life
Seal-less Pump
Magnetically Coupled Rotor- has no contacting or wearing surfaces so it will not leak
Warranty
Up to 3 years as a replacement
Up to 7 years if specified in new build
Cost
Typically $350 to $400
Only pump you ever need to buy

7. Life Cycle Comparison
Save $2,650!
Assuming a 12 year lifespan for a fleet of 100 buses, $174,700 could fall DIRECTLY to your bottom line!
Save $1,747!
Save $947!
* Numbers reflect a per bus calculation based on the need to replace sealed pump every 2 years
