Our dual pump cementing unit is a complete mixing and pumping unit that can be skid or trailer mounted. This unit is state-of-the-art in mixing and automatic control. This system is designed for the most demanding oil and gas well cementing requirements. The quality of design, component selection, and quality manufacture makes it a benchmark in the industry.

The high energy mixing system can mix the most difficult slurries and the ACM automatic density control will provided superior density control. The pump unit can be utilized for a variety of pumping services including acidizing (less than 30%), cementing, pressure testing and fracturing within the limits of the available horsepower. The inline triplex pump installation makes the maintenance and service of pumps easier.

This system is designed for minimum maintenance and operating in extremely harsh environment with temperatures ranging from -25 ^oC to 50 ^oC and relative humidity up to 90%.
