Pumping of Concrete: System, Working and Problems ...

Usually concrete can be pumped along a straight and level pipe line for a distance of about 300 to 450 m and upto 40 m vertical height using a single pump. Any rise of 30 cms is equivalent to m on the level ground and a right angled bend is equivalent to about 12 m. Hence for a bend of 90° a horizontal distance of 12 m and for 22 ½° bend 3 m horizontal distance should be reduced. No ...
