    Overview

     

    Our single-stage DVSHF and double-stage THF/DS-THF pumps are centerline mounted, horizontal, staggered single or double volute, vertically split, with impeller between bearings. They meet the API610 standard for BB2 pumps.

    These pumps are designed for continuous duty and are particularly well adapted to oil refinery and other industrial services, pumping fluids under a wide range of temperatures and pressures. Stuffing boxes are designed for API682 mechanical seals. The THF family includes a double-suction first stage option called DS-THF, for low net positive suction head (NPSH).

    Multiple options can be required to fit any process and plant requirements. antifriction or sleeve bearings are available as well as ring or forced feed lubrication. Cooled or jacketed casings are available to achieve reliable service during transient and steady-state operations. All pump stuffing boxes comply with API682 minimum requirements and can host any type or style of mechanical seal.
