Ball-Valve Concrete Pumps| Concrete Construction Magazine

Reverse pumping links the concrete piston in the suction stroke and S-Tube valve to suck concrete from the s-tube instead of the hopper. As a result, the concrete piston pumps concrete into the hopper. The power for operation of the concrete pump is provided by the engine, which drives the hydraulic pumps. All functions for operation of the

AMERICAN CONCRETE PUMPING ASSOCIATION

The purpose of certification is to increase the safety awareness of concrete pump operators and to assist in an operator's development and self-improvement. Certification thus permits concrete pump operators to raise the professional standards of the industry by maintaining and improving safe operation of concrete pumps.

driven ball-valve pumps generally handle grout with 1⁄ 2-inch-maxi-mum aggregate. Swing-valve ma-chines handle 3⁄ 4-inch and larger aggregate mixes, so they can be used for both grout and concrete. A pump with a swing valve can be reversed to pull the grout out of the line or to help clear line block-ages. Ball-valve pumps, in con-

Concrete Pumping - How to Pump Cement - Concrete Network

When concrete is pumped, it is separated from the pump line walls by a lubricating layer of water, cement and sand. Naturally, the concrete mix must be suitable for its particular application, but it must also contain enough water for the mix to move easily through the reducers, bends and hoses found in most basic pipeline setups.
