I think that the missing piece is that a pump with a fairly small diameter piston is used to overcome the tremendous fluid friction of the grout.
If you have access to a lathe, you could probably build a motorized one. Commercial grout pumps are horribly expensive.

It only costs about 1000 $$. If I could find used one for 200-300$$. There are other ones using the same idea(They used for concrete Mudjacking). But they all in 1000$$ range. I want to keep price affordable for DIY person. If I was doing this for a living no problem 4-5k pump will pay back.
