Liquid Additive System
The liquid additive skid can automatically and continuously mix the liquid additives used for cementing, instead of manually adding and measuring on site. The motor frequency conversion technology is used to control the displacement of the metering pump, which is easy to control, fast in response and accurate in metering.
LAS is divided into four modules, and 4 metering pumps are differentiated. It can be used in any combination of 2-4 depending on the process or space requirements.LAS uses frequency conversion motor technology to control metering pump displacement, easy control, fast response, accurate measurement.
