Direct Drive	vs.	Belt Drive
1. Less Expensive a. Smaller footprint, lighter b. Pump bolts directly to pump c. Smaller Components d. Smaller platform		1 More Expensive a. Larger, weighs more b. Cast Iron Pulleys c. Notched Belts d. Belt Guard
2. Vibration - Passed back and forth		2. Vibration - Absorbed by belts
3. Speed of Pump Rotation 3000, 4500 RPM's, bearings wear out faster.		3. Speed of Pump Rotation 1100- 1400 RPM's, Last up to three times longer
4. Runs Hotter - Oil End Seals & Valves become brittle and wear out FASTER		4. Runs Cooler - Oil End Seals & valves last longer, less maintenance
5. If Pump Freezes Up Could throw shaft in motor		5. If Pump Freezes Up May only lose belt, if that
