1.Overview

PCS-621B Auto density control double pump cementing skid is new generation of cementing unit with adoption of plunger pump TPB600 and ACM-lll.1 auto mixing system.

SERVA TPB600 pump has prominent features of small volume and light weight. With two pump back to back installation, the overall width will onlg be 2580mm which can extremely decrease the overall dimension (weight）of unit, especially applicable to truck-mounted units or offshore equipments.

The high energy mixing system is mainly powered by two transmissions PTOs. The entire skid is very compact so it is applicable for the areas with strict requirements for space, such as offshore drilling platform, etc.
