The model of PCS-421B is a skid mounted complete mixing and pumping unit. This unit is state-of-the-art in mixing and density automatic control.
It mainly consisting of seat, two engines, two transmission boxes, twoTPA400 triplex pump, hydraulic system, air system and ACM-III auto mixing system. The drive of HEMI system is from two transmission boxes PTO, the skid is compact and suit to offshore drilling. 
This unit mainly used in oilfield cementing, fracturing, oil well pressure testing, and other fluid pump in offshore, on land or desert.
