概述
概述
Our单级DVSHF和双阶段THF/DS-THF泵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).
可能需要多个选项以适应任何过程和植物要求。提供抗固定或袖子轴承以及环或强制进料润滑。可以在短暂和稳态操作期间获得冷却或外套的套管以实现可靠的服务。所有泵填充盒均符合API682最低要求，并且可以容纳任何类型或样式的机械密封件。
