Animation css svg pump - css

Question

Could someone help me with the amination of an svg?
I am trying to create an animation of the pump impeller. What I want is for the last 4 elements of svg to do a rotating impeller effect. Make it look like it is rotating. The real effect would be to raise the elements one position and the one that is left above appears below and so on while it is on. I have no idea how it could be done. Thanks a lot

Answer 1

This is how I would do it: I would replace those paths with a very thick line with a stroke-dasharay and I would animate the stroke-dashoffset of the line.
#keyframes on {
100% {
stroke-dashoffset:1920
}
}
.on {
animation: on 0.8s infinite;
}

Observation: I've modified the second path since I wanted to remove the bit corresponding to the rotating engine.
