We have a special liquid pump which is about 6cm in diameter. This pump has a big resistance which is about 32000kg. We plan to push the piston of the pump very slowly at about a rate of 0.0265cm/min. The piston will be threaded and there will be gears in between the motor and piston to reach the required speed. What we should do to choose a right motor? 1. Calculate the output torque and power needed for the motor and 2. with the calculated output torque and power to find a motor manufacturer? AND we also need your help about how to calculate the required output torque and power. Please help. Thanks,
