Which eccentric mechanism to choose for my tool ?

Hi folks, I am using a hand driven pump like the yellow  one on the picture .  I want to use an engine for that pump instead of using my hands and a pump arm. 

I will disassamble the long arm from my yellow pump and will want to transmit engine power to the piston. 

Engine power is 0.6 kW

rotation of my engine  is 60 per minute. 

Shaft  on the engine will need to be able to rotate  under load  approx 400 kG 

Can you please advice which way is best for transmission of the engine power to the piston   ? I have few example below, but maybe there is a better way ?

THank you for help ! 

Frank 

by the way 

will the engine 0.4 kW ( 50 rpm)   be strong enough for that job ?

When you click the topic, it takes you to the new location. You originally had this in the PE exam preparation --> Mechanical area. But this belongs in the Technical Discussion --> Mechanical area. :thumbs:
