The secondary structural column pump adopts hydraulic slurry delivery, and the reciprocating operation of vibrating screen filter double cylinder can transport various mortar and fine aggregate concrete in building applications. It has the characteristics of large displacement, high pressure, labor and material saving and flexible movement. It is an ideal special pump for structural column pouring. It can be widely used in some special construction environments, such as railway and highway tunnels, headrace tunnels, culverts, mine tunnels, bridge tunnels and other tunnel body construction, as well as filling works of water conservancy projects, hydropower projects, slope support, underground construction operations and other foundations.
