What are the technical characteristics of concrete pumps

Fundamentals Of Pumps

Centrifugal pumps can also be constructed in a manner that results in two distinct volutes, each receiving the liquid that is discharged from a 180. o. region of the impeller at any given time. Pumps of this type are called double volute pumps (they may also be referred to a split volute pumps).

8 ESSENTIAL QUALITY REQUIREMENTS OF PUMPED CONCRETE

Mar 21, 2016 · Concrete pumps can be either truck- or trailer mounted and range from small units, exerting pressures from 250 to 300 psi and outputs of 15 to 30 yd 3 /hr, to large units, exerting pressures of 1,000 psi and outputs up to 150 yd 3. The effective capacity of a pump depends not only on the pump itself but also on the complete system.

Assessment and prediction of concrete flow and pumping

Mar 01, 2020 · Concrete flow in a pipeline is a complex material response to the induced pressure accompanied by shear in LL [], friction between solid particles and pipe wall [10,18,19], and significant hydrodynamic interactions among particles within the partially sheared concrete bulk [20,21]; cf. Fig. 2.The extent to which frictional resistance is active depends on the state of saturation of the concrete

Concrete Pumping - How to Pump Cement - Concrete Network

Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.

What Makes Concrete Pumpable?| Concrete Construction Magazine

Nov 01, 1991 · In a pump line, concrete moves in the form of a cylinder or slug separated from the pump line wall by a lubricating layer of water, cement, and fine sand. To keep moving through the line, the mix must be dense, cohesive, and have sufficient mortar. When concrete is pumped, if spaces or voids between aggregates are not filled with mortar, or if the mortar is too thin and runny, pump pressures
