What are the basic parts of concrete pump?
Agitator shaft, agitator gear box , agitator support , agitator pumping cylinder , pumping piston , bushing .
How many types of concrete pumps are there?
There are mainly three types of concrete pumps: Boom or truck mounted pump. Trailer, line, or stationary pump.
How do you clean a concrete hopper?
The concrete line can be cleaned with water or air pressure. The first option (water) is the most recommended, because it is more effective and safe. Fill the hopper with water and put a foam ball in one end of the line, so that when pumping, it runs through the line and sweeps out the remaining material.
What is the largest size aggregate that a pump operator should attempt to pump with a mechanical ball valve pump?
When pumping, the maximum size of the coarse aggregate is limited to one-third of the smallest inside diameter of the pump or placing line.

What type of pump is used for concrete?
There are two main types of concrete pumps—boom pumps and line pumps. Both of these pumps can reach over, under, high up, deep down below, and far away from the concrete mixer trucks to pour concrete quickly and accurately.
Which type of pump is used for concrete pumping?
It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom.
How does a ball valve concrete pump work?
A ball valve is actuated entirely by flow of the concrete. On the intake cycle, ball movement at the feed hopper is limited by bars or an off-center cam. On the discharge cycle, concrete flow seats the ball. The ball at the discharge cylinder seats during intake and opens during discharge.
What is the minimum pH of water for mixing concrete?
6.0
As per IS 456:2000, the pH value of water for concrete mix shall NOT be less than. 6.0. 5.0.
