1. 6.5 HP (power) = 4.784 kilowatts, but this is the output power of the generator, which is the input power of the water pump motor.
2. The rated power of the water pump motor is its power output. The required input power = output power / motor efficiency is about 0.7 ~ 0.8, so the motor power range. The corresponding water pump motor is 3 ~ 3.8 kilowatts. However, the motor power levels are 3 kW and 4 kW, and only 3 kW can be selected.
3. Since the generator power is low, when purchasing water pumps and motors, you should choose products with higher efficiency. The efficiency of the water pump and motor must be indicated on the nameplate. However, the price of more effective products is relatively high, but this will be compensated by long-term application in the future.
