Please advise squeeze concrete truck pumps (sample picture attached) ? is squeeze pump compatible with normal hydraulic pump ? can it handle regular concrete ? if squeeze pumps functions the same as hydraulic why it casts much cheaper? As you are concrete pump specialists your information will be highly valuable

They  don't work like a regular Schwing  or Puzt I know someone that has one and the Ready Mix drivers hate hauling to him  he plugs a lot.

My opinion is stay with a S-tube boom pump

Concrete made ​​with 35% gravel 4 / 16 mm
