Specifications on Concrete Pumps

Concrete pumps are used to help the flow of concrete fluid by performing a physical or mechanical action. There are a couple of different types of concrete pumps and valve types. The cylinder that all concrete pumps use is a hydraulic cylinder.

Types: There are two types of concrete pumps: line type and boom type. Line concrete pumps are in a trailer or are mounted to the truck. These pumps connect to the outlet of the pump through hoses. These hoses transport the concrete to the place where it is supposed to go. Boom concrete pumps are fastened to the trailer. These pumps use a boom, which is a robot arm that is controlled by a remote, to move concrete.

Valve Types: The valve type that is used on a concrete pump is normally determined by the manufacturer of the pump. Several types of valves include rock valve and a gate type valve. A rock valve is a one action valve. While the piston is in the forward stroke, the rock valve pivots, opening the intake cylinder. The rock valve pivots again to attach the pump discharge line to the cylinder when the piston ends the stroke. The gate type valve has two different valves. One of the valves controls the flowing cement and the other controls incoming cement by closing and opening.

Cylinders: There are two hydraulic cylinders in concrete pumps. A valve lets the concrete flow in a pump discharge line.
