Placing Concrete by Pumping Methods

A steady supply of pumpable concrete is necessary for sat- isfactory pumping.1 A pumpable concrete, like conventional concrete, requires good quality control, i.e., uniform, properly graded aggregate, materials uniformly batched and mixed thoroughly.2 Concrete pumps are available with maximum output capacities ranging from 15 to 250 yd3/hr. Maximum volume output and maximum pressure on the concrete cannot be achieved simultaneously from most con-crete …

How Does A Concrete Pump Truck Work? Learn How Concrete

Some concrete pump trucks have different types of valve systems, s-valves, ball-valves, but basically that's how a concrete pump works. As long as the hopper stays full and there are no blockages in the concrete hoses, the process of pumping the concrete goes quite smoothly. Having a good concrete pump truck operator is also very important.

Concrete Pumps | What is a concrete pump?

A concrete pump is a tool for conveying liquid concrete. Over a period of more than half a century, concrete pumps have slowly taken over from other methods of transferring liquid concrete. A number of different designs of concrete pump were developed in the first half of the 20th century but it was Friedrich Wilhelm Schwing's company Schwing

Ball-Valve Concrete Pumps| Concrete Construction Magazine

Many ball-valve rigs are mechanically driven. These have one concrete pumping piston driven off a series of belts, chains, and a crank. Hydraulic-drive ball-valve pumps use a two-cylinder hydraulic drive much like those on large-rock pumps. Hydraulic pumps can pump concrete at a faster rate and at higher pressures than mechanical pumps. PUMPLINES

How a Concrete Pump Works| Concrete Construction Magazine

Aug 01, 1994 · How a Concrete Pump Works. The pumping operation starts with the discharge of the concrete, usually from a ready mix truck, into a hopper large enough to hold a small supply of fresh concrete. In the hopper an agitator keeps the fresh concrete flowing smoothly into the pumping cylinders. Concrete piston pumps operate on the same principle as a
