New Designed Concrete delivery pump Trailing concrete
Burj Khalifa – a new high for high-performance concrete
May 02, 2010 · Concrete pumping trials were conducted before the Burj Khalifa tower construction using a Putzmeister BSA 14000 HP-D stationary pump with a maximum hydraulic pressure of 310 bar. A length of 600 m of high-pressure ZX 125 delivery pipe was laid out horizontally with transducers to measure concrete pressure after pumping through distances of 250
Trailer Concrete Pumps - How to Pick the Best Pump
Pea-rock pumps, for example, are designed to pump cement-based mixtures containing a 1/2-inch top aggregate size, such as repair grouts, shotcrete, and self-leveling overlays. Other line pumps can handle higher-slump concretes containing larger coarse aggregate (3/4- to 1 1/2-inch rock). These models are better suited for placing concrete slabs
Some concretes are even designed to harden more quickly for applications that require rapid set time. Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls. The process of concrete hardening once it has been placed is called curing, and is a slow process.

Pumping concrete using concrete line pumps and concrete boom pumps can make your concrete placement much easier and faster.After all, the concrete pump truck does most of the work of getting the concrete where you need it. In the video above we used a pump truck to help pour a colored basement concrete …
Atmospheric pushes the oil from the reservoir to the pump inlet. Pumps are designed to be fed, not to draw oil. For this reason, it is desirable to place the reservoir directly above the pump inlet. This is also why we refer to the pump's inlet port rather than its suction port. Atmospheric pressure at sea level is 14.7 PSI and approximately
How to Specify and Use Concrete Pumplines| Concrete
Jun 06, 2012 · This phenomenon can happen at the start of delivery when concrete is first pumped through the line, whenever the line is broken apart and reassembled, or when the concrete level in the pump hopper gets too low, allowing air to enter the pump. Air introduced into the line is compressed by the pressure exerted by the pump on the concrete.
