INTAJ LLC fluid pumping units are fully integrated, with redundant twin quintaplex pumping units. Engine size and pump performance have been selected to support larger OD coiled tubing operations or standalone pump down treatments with 24-hour, continuous operations. The units provide improved flow rates and annular flow velocities at design circulation pressures. In addition the units feature an in-line, heated, chemical additive system, which improves the efficiency, accuracy, and safety of milling and cleanout applications
