1.Overview

Model PCS-521B double pump cementing skid equipped with TPH400 pumps is new generation of cementing unit developed in recent years.

The input shaft of TPH400 pump is paralleled with centre line of engine, so the fluid end is at the rear of unit. This inline installation feature makes the maintenance and service of pumps easier.Compared with other cementing plunger pumps with same plunger size,TPH400 pump has features of maximum operation pressure, long stroke and high self-priming capacity.The high energy mixing system is powered by the transmissions PTOs. The skid is very compact, so it is applicable for the areas with strict requirements for space, such as offshore drilling platform,etc.

This unit is mainly utilized in cementing job, acidizing job, oil well pressure testing, and other fluid pumping job in ofshore, on land or desert oilfield.
