PCS-421B Auto Density Control Double Pump Cementing Skid

Product Explanation: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.

Product Features:

1.patent right of high energy mixing system

2.Patent right of off-center dry cement valve, avoid from bulk-blocked

3.Emergency kill system of engine is used for air inlet shutoff

4.Big pump’s over-pressure protect idle system

5.SPS’s non-leakage packing system

6.Spare mixing system to meet the urgent

7.non-radioactive densitometer, less cement-blocked, safe and reliable

8.Adapt to oilfield work custom, simple operation steps

9.10 inches large size of display, easy to input data and test

10.portable wireless or wire data collecting system

11.Engine auxiliary cold start, pneumatic and hydraulic start
