Double Pump Cementing Trailer

PCTLR-521A double pump cementing trailer adopts TPH400 piston pump as cementing pump. The complete unit consists mainly of a semi-trailer chassis, two main engines, two transmissions, two TPH400 triplex pumps, C7 power unit, hydraulic system, air system, and ACM-IV.1 Automatic Mixing System. The input shaft of the TPH400 pumps is parallel to the engine centerline, so the fluid end is located at the rear of the unit. The TPH400 pump is characterized by high working pressure, long stroke, and high self-priming capability compared to other cementing piston pumps of the same plunger size.
