Crush Strength

 · For freshwater, 1200 psi works out to an equivalent head (or depth if you were in a submersible) of 2771 ft. For very little money, a person with some welding and fab skills and equipment could build a test tank and learn a lot about the crushing pressures & failure modes for a thinwall stainless steel shell.

and this reduces the crushing force. If the diameter of the crank plate is high, then the piston reciprocates slowly and the crushing force exerted by the piston will be really high thus damaging the bin which is at the end of the piston. Therefore, optimum diameter of the crank plate should be maintained for the effective operation [3].
