1.Overview

Model PCS-421B is an integral skid mounted mixing and pumping unit which is state-of-the-art in continuous mixing and density automatic control.

It mainly consists of skid frame, two engines, two transmissions, two TPA400 triplex pumps, hydraulic system, air system and ACM auto mixing system. The High energy mixing system is powered from two transmissions PTO. The entire skid is very compact and applicable for offshore drilling platform.

This unit is mainly utilized in cementing job, fracturing job, oil well pressure testing, and other fluid pumping job in offshore, on land or desert oil field.
