Above is the link of the brief description of the machine. I really hope someone tell me how does the machine work with no motor, no gearbox, no pump. Is this machine working similar to a hydraulic pump?

Answer 1

Simple dude.

It SQEEZES the resin down into the pail forceing it out the tubing.

Instead of a pump to pickup, then pressureize the push out the tube.

It is basically like a tooth paste tube.
