Mechanical Devices: An Overview of Concrete Pumps

Main Parts Of A Concrete Pump

Valves: Concrete pumping equipment can function through hydraulically-powered valves or ball-checked valves. Hydraulic valves are capable of handling different cement mixtures and can pump up to 250 cubic yards of concrete per hour. Ball-checked valves, on the other hand, use balls and mating seats to control cement transfer from the hopper to the cylinder and pipeline. These are ideal for pumping smaller volumes of cements through thinner pipelines.

Cylinders: One cylinder connects to a hopper, while the other dispenses to the pipeline.

Pumps: The first designs were mechanical and have basic functions. Contractors pour cement into the hopper connected to the cylinders through a valve. The valve closes and a piston will push the cement into the pipeline. Hydraulic pumps, however, were later introduced and increased the efficiency of transferring liquid cement.

Pipeline: The pipeline must be robust and durable. It must also be light so contractors can easily carry it throughout the site. The pipeline consists of two parts: boom hose and discharge hose. The boom hose is made of steel alloy, while the discharge hose is made of lighter and flexible material.

Two Types Of Concrete Pumps

Concrete pumps come in two types: boom truck and line pump. Boom trucks consist of a truck, frame, and the pump itself. These are ideal for pouring cement into slabs and medium high-rise buildings. These vary from single-axle truck mounted pumps, suitable for confined areas. These use a remote-controlled robotic arm, called a boom, to transfer cement accurately. These are suitable for large construction projects because they can pump at high volumes.
