High pressure safety valves are used the discharge the high pressure in the cement silo. Those valves start to run when the pressure value reaches the pre-set pressure limit value. Those valves are the equipments that keeps the pressure in the cement silo in desired values and prevent the cement silo filter from breaking down.

New heights reached in concrete pumping - World Pumps. Back in November 2007 a new world record height of 601 m for pumping concrete was set by a Putzmeister 14000 SHP D super high pressure concrete pump being operated by Unimix on the Burj Dubai Tower in Dubai.

Trailer pumps can pump up to 2,000ft. vertically and up to 8,000ft. horizontally. They are extremely versatile and can pump concrete almost anywhere for high-rise structures, underground tunnels and shafts and even underwater for marine construction.

High-pressure water jetting can be used for a wide range of concrete applications. A high flow high-pressure water jet can cut through concrete by eroding the cement. At high pressure with a lower flow, water can actually remove coatings without damaging the sound concrete below. Add an abrasive to the jet and water can completely cut through a ...

High pressure concreting. Liebherr manufactures stationary concrete pumps for flexible use. Our trailer and crawler concrete pumps provide economic solutions for long-distance and high concrete conveyance via concrete lines or concrete distribution systems.

3.1. Concrete specimens Two different kinds of concrete were investigated. The first one, called “control concrete”, was made only with non-reactive (crushed limestone) aggregates. The second one, called “reactive concrete”, in contrast, was made using the same mixture but replacing the coarser fraction of aggregates with crushed colorless

Grout pumps can be used to fill small voids and door jams and they are available in either manual, electric, gas, hydraulic and air powered. Concrete pumps are strong enough to lift up many stories and even lift slabs of concrete. It's worth mentioning that certain model concrete pumps

Dependable High Pressure Water Pumps. High pressure water pumps have reliable engines that push water long distances or to great height. With powerful GPH flow rate, these high pressure water pumps work great for sprinkler systems, local firefighting, or washing down vehicles.

Line length: 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.

Trailer pumps can pump up to 2,000ft. vertically and up to 8,000ft. horizontally. They are extremely versatile and can pump concrete almost anywhere for high-rise structures, underground tunnels and shafts and even underwater for marine construction.

high pressure relief valves for cement silos

High pressure safety valves are used the discharge the high pressure in the cement silo. Those valves start to run when the pressure value reaches the pre-set pressure limit value. Those valves are the equipments that keeps the pressure in the cement silo in desired values and prevent the cement silo filter from breaking down.

A concrete pump is a machine used for transferring liquid concrete by pumping. It Includes two main types i.e. boom concrete pump and line pump or trailer-mounted concrete pump. There are different parameters like Manufacturer of the Concrete Pump, Price, and economic factors, etc.
