WL company concrete trailer pump for sale is a kind of S-tube valve drag pump, and the conveying aggregate size is 40mm. The equipment is mainly used for concrete construction of railways, highway tunnels, bridges and culverts, hydropower, mines, high-rise buildings and other projects. It greatly improves the construction efficiency of engineering buildings, saves labor costs, shortens the construction period, and expands economic benefits.
In order to meet different engineering needs, Qingdao WL company has developed a variety of concrete pump trailers to provide customers with diversified choices. 
According to the pumping capacity, we have 30 / 40 / 50 / 60 / 80 / 90 CBM/H models concrete pumps.
You can choose the appropriate equipment model according to your construction project type !
According to the diameter of pumped aggregate, it can be divided into fine stone pump and large aggregate pump.
NOTE: The fine stone pump can pump the maximum particle size of aggregate ≤30mm. The large aggregate pump can pump the maximum aggregate particle size ≤ 40mm.
According to the power, it can be divided into Electric drag pump / Diesel drag pump
1. The Diesel power drag concrete pump : Diesel trailer pumps are suitable for projects with power shortage and difficult conditions.
