1.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, C7power unit, hydraulic system, air system and ACM-IV. 1 auto mixing system.

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.
