China Double Pump Cementing Truck by Serva

1. Overview
PCT-521A Double pump cementing truck is mainly utilized for cementing, acidizing, pressure testing and other fluid pumping jobs, with standard configuration of VOLVO FM440 6X6 chassis.
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 pumps with same size of plunger, TPH400 pump has features of maximum operation pressure, long stroke and high self-priming capacity.

3. FeaturesTPH400 inline installation, makes the maintenance and service of pumps easier.The mixing power is partially supplied by chassis engine which increases the actual operation power of deck engine.High energy recirculating jet mixing system.Off-center dry cement valve avoids bulk cement from choking.Emergency kill system of air inlet shutoff.Plunger pump overpressure protection system.SPS non-leakage packing system.Plunger pump overpressure protection system, engine goes back to idle automatically, transmission shifts to neutral position.F300 Non-radioactive densitometer is easy to wash, safe and reliable.Simplify operation, adapts to working habits in oilfield.10" operation screen, convenient to monitor the working data.Portable wireless/ wired data acquisition system.Diesel fired coolant pre-heat system available. The heater allows the engine to be preheated before starting without the use of external power.
