PCT-521A Double Pump Cementing Truck SERVA
1. Overview
The PCT-521A double pump cementing truck is designed primarily for cementing operations, acidizing jobs, pressure testing and other fluid pumping applications. It comes standard with a VOLVO FM440 6X6 chassis.
The input shaft of each TPH400 pump runs parallel to the engine centre line, positioning the fluid end at the rear portion of the unit. This inline mounting layout simplifies routine pump maintenance and servicing. When compared against other cementing plunger pumps equipped with identical plunger sizes, the TPH400 delivers advantages including higher maximum operating pressure, extended stroke length and improved self-priming performance.

3. Features
- TPH400 pumps adopt inline arrangement, lowering barriers for all pump maintenance and field servicing work.
- Partial mixing power is supplied from the chassis engine, boosting the effective operating power output of the deck engine.
- Equipped with high energy recirculating jet mixing system.What’s app +8615972752793Luben@youlongpetro
- Off-center dry cement valve structure prevents bulk cement blockage.
- Fitted with emergency kill system of air inlet shutoff.
- Integrated plunger pump overpressure protection system.
- Utilises SPS non-leakage packing system.
- The overpressure protection function automatically brings the engine back to idle and shifts the transmission into neutral when abnormal pressure occurs.What’s app +8615972752793Luben@youlongpetro
- F300 non-radioactive densitometer allows easy cleaning while maintaining safe and stable operation.
- Streamlined operation layout matches common operational practices adopted in oilfield sites.
- A 10-inch operation screen enables straightforward real-time monitoring of operational parameters.
- Supports portable wireless and wired data acquisition system.
- Optional diesel fired coolant pre-heat system. The heater enables engine preheating prior to startup without external power supply.
