China Double Pump Cementing Trailer From Serva China

The cementing trailer is the economic and mobilable cementing unit, applicable for cementing, acidizing, oil field pressure testing and other fluid pumping jobs in remote oilfield environment such as desert, etc.
Three kinds of major cementing plunger pump of TPA400, TPH400 or TPB600 and variety of plunger size can be selected according to different operating conditions and working habit. Desert type of trailer is also available.
PCTLR-521A Double pump cementing trailer
I.Overview
PCTLR-521A Double pump cementing trailer adopts TPH400 plunger pump as cementing pump.
The whole unit is mainly composed of semi-trailer chassis, two main engines, two transmissions, two TPH400 triplex pumps, C7 hydraulic power unit, air system and ACM-IV.1auto mixing system.
The input shaft of TPH400 pump is paralleled with centre line of engine, so the fluid end is located 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.
