Secondary structure column pump features

The main features of the secondary structure of the column pump: The slurry pump with dual-piston, electro-hydraulic control, S-tube valve distribution, with the system stability, control system is simple, easy to operate, less maintenance and other advantages . Secondary structure Column pump features The use of pump power is very small, in the absence of power only need to be equipped with a minimum generator to work, is the youngest concrete pump, is the only one of the narrow construction environment select. High pump configuration, hydraulic operation, stable performance, compact structure, low failure rate, for the construction of the column note, good continuity, high transmission efficiency, is manually poured concrete hundreds of times. The main seals use PARKER (PARKER) high-quality seals, to eliminate the internal and external leakage of the hydraulic system. Widely used in some special construction environments, construction of railway tunnels, diversion tunnels, culverts, mining holes, bridge holes and other holes in the body, including water conservancy projects, hydropower projects, slope support, underground construction operations, basic filling projects, large Qunlou building structure column pouring and so on. The secondary structure of the pump's advantages: full mechanized operation, is manually pouring concrete hundreds of times, shortening the construction period. This pump pouring concrete continuity, transmission efficiency, saving labor costs. This pump small size, easy construction, simple operation, the floor can be poured directly, greatly reducing labor intensity.

Carbon Slip On Flange is a kind of Carbon Steel Flange connected to a container or pipe line. Slip on flange is suitable for pipeline system with low pressure level and low pressure fluctuation, vibration.  SO flange is widely used because of its easy alignment and low cost in welding and assembling.
