Concrete Pumps - Types and Selection - The Constructor
The concrete pumping to different heights like in the construction of high-rise building can be performed by boom concrete pumps. Boom concrete pumps allow the pipeline to reach along, upwards and below. Hence tight spots can be cast by these pumps. Obstacles during the concrete casting path can be easily overcome by such pumps. 2. Line
6 Basic Rules of Pump Piping - Crane Engineering
Include a straight run pipe length equal to 5 to 10 times the pipe diameter between the pump inlet and any obstruction in the suction line. Note: Obstructions include valves, elbows, "tees", and etc. Keeping the pump suction piping short ensures that the inlet pressure drop is as low as possible.
Concrete Pumps | What is a concrete pump?
A Static Concrete Pump, also referred to as a Stationary, Line Pump or Trailer Mounted Concrete Pump is mounted on a trailer and requires a separate pipeline to be attached reaching to wherever the concrete needs to be placed. The pipeline is a series of steel or rubber pipes, known also as concrete placing hoses, linked together and manually
Major Problems in Concrete Pumping Works: How to Avoid
The major problems that one encounters when pumping concrete are blockage of pipeline, and segregation and bleeding of concrete mix. Blockage is the failure of concrete to emerge at the end of the pipeline. It is characterized by an increase in pressure that can be observed on the pressure gauge. Blockage can be caused by improper selection of
Concrete Trailer | Line Pumps For Sale
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.

Concrete Pump Blockage - Causes & Clearing - Concrete Network
A rise in line resistance, as shown on the pump pressure gauge, indicates line blockage. The first suspect spot for blockage is the reducer, which connects the concrete pump to the pipeline system. A quick build-up in pressure prior to the jam indicates the blockage is most likely in the pump area.
Pumping Concrete: Line Pressure and Equipment Choice
Line pressure requirements also depend on pipeline layout. The length of straight and horizontal pipeline, the vertical rise, the number and severity of bends, the amount of flexible hose used in the line—each has an effect on pressure needed to move the concrete. DIAMETER OF LINE. While a larger inside pipeline diameter cuts down on the pressure needed, it also has one enormous drawback: the larger the line, …

The external gear pump is the ultimate solution for high pressure pumping. Bearing support on both sides of the gears enables differential pressures to 500 PSI (34 BAR), or Intermittent to 2,500 PSI (170 BAR) Motor speed operation eliminates cost of speed reducer. Eliminates lubrication – no external axial or radial bearing required in most
