World's FIRST hydraulically operated concrete pump which does not require a hydraulic pump.
Ғылым және технология
This is it. World's first hydraulically operated but mechanically driven & mechanically reversed self regulated simple concrete pump. Protected by international patent application no. PCT/IN2014/00088 & Indian patent application no. 3871/MUM/2013.
This is the prototype under testing with exceptionally low engine rpm (1200) and lowest stroke-length & lowest no. of strokes per minute. The prototype is also fitted with self regulating, auto-actuated highly efficient rotary valve mechanism which is protected under Indian patent application 2198/MUM/2014 & corresponding PCT application. The valve has better suction characteristics compared to the Swing tube. This is because of the fact that the swing tube occupies more space in the hopper and adversely affects suction. This new valve also insures minimum displacement of concrete during each operation & hence is subjected to minimum wear. The concrete displaced is much lesser compared to the S-tube as the S-tube has to move through the concrete during each swinging action.
A full fledged commercial version is followed especially for the entry level placements. This pump shall be useful for pumping approx. 16 cubic meter per hour and a vertical height of 40 meters . The hopper shape is further modified and is designed for higher capacity (0.4 cubic meter) and is provided with a re-mixer shaft. And of-course a well designed canopy and a very small drive cylinder. The USP of the pump is low capital & operation cost with low maintenance cost due to its simple design.
Bigger models with 30 Cubic meter per hour & above shall be shortly introduced in single & twin cylinder designs with same operating principle. All the currently available hydraulic concrete pumps cannot achieve the maximum pressure & maximum output at the same time. However this pump delivers the same output irrespective of the pumping pressure.

Very interesting but i can say i could completely trust this machine in a high volume pour
Protect the cylinder because the cement will dry and eventually work it's way into the seal scratching and gouging the piston. I'm curious to what the pro's and con's are on this prototype. Good for your team to take this invention and run with it. I wish you much success!

True....I agree.Place boots over chrome cylinders on pistons.I would also design hydraulic circuit to use exhausted fluid from non pressure side of piston to minimize flow requirements and increase productivity.Shalom
Thanks for your posting, We used to pump very very at most maximum of 13 m3 per hour, there is no use of inventing a pump more than 15m3 per hour pump...and maximise the hopper capacity,
This is very similar to the "Rex Pumpcrete" a machine built in the 1950s
That hydraulic cylinder is in the wrong position as the rod would not last too long with exposure to abrasive concrete
how big is the aggregate sir? can it be used for average 30-40mm aggegate?
hola que origen es la maquina y en donde se la puede comprar
Good
how much storey or feet can it pump horizontal and vertically?
Im curious what is creating the pressure to operate the cylinders. It would appear to me that there is a hydraulic pump being driven by the engine. Least pumps maybe? Is that a transmission rather than a hydraulic pump? Either way whats creating the pressure and volume to move the cylinders?

Looks like a flywheel based system
I am missing a flush box to cool the concrete cylinders/pistons..
good achievement

That its hydraulic concrete pump
if you invent another 2 cylinder pump it faster
