China Serva Double Pump Cementing Truck

1. Overview
PCT-621A double pump cementing truck adopts TPB600 pump with the features of compact structure and light weight, with standard configuration of VOLVO FM440 6X6 chassis.
SERVA TPB600 pump has prominent features of smaller volume and lighter weight. With two pump back to back installation, the overall width will only be 2580mm which can extremely decrease the overall dimension (weight) of unit, especially applicable to truck-mounted units or offshore equipments.
