·         Application                                                  e.g.       Irrigation water pump

·         HP or KW required                                                   20 hp

·         What speed                                                             2500 rpm

·         Direct coupled or belt driven                                      Direct coupled by flexible coupling

·         Ambient conditions                                                  Up to 400C, 30% humidity

·         Site conditions                                                         Under cover on farm site

·         Duty – continuous or intermittent                               Continuous 2500 hrs per year

·         Other factors –         engine exhaust emission ruling requiremnts, side loads, mountings, vibration, electric’s,
                              maintenance and service points, noise levels, shock loads, exhaust emissions, etc.
