Kilowatts Required | 5 | 10 | 15 | 20 | 25 |
For operation below 70 RPM, an auxiliary lubrication system is required.
RPM shown is Crankshaft speed. For Pinion Shaft speed, multiply RPM by Gear Ratio. Volumetric Rate is based on 100% Volumetric Efficiency. Brake Horsepower/Kilowatts Required is based on 85% Mechanical Efficiency.
