Features: ISO 13709/API 610 OH6 Integrally Geared Pump GSB-L1 are single-stage, single-suction, vertical part-flow centrifugal pumps. The inlet and outlet flanges of the pump body form the symmetry on the same horizontal line, with strong structure rigidity and high piping bearing capacity. The impeller uses the open-type straight blade centrifugal impeller arranged on the output shaft of the speed-increasing gearbox, which can enhance the pump’s efficiency point and hydraulic performance. Unique pump case diffuser design guarantees the cuttability of the inherent head, without worrying about the motor overload caused by the change of the working conditions or misoperation. The front-mounted inducer design can enhance the suction performance and high cavitation performance, and reduce the pump’s NPSHr. The high-speed shaft bearing uses the copper alloy sliding bearing. Its good lubrication system makes its linear velocity up to 50m/s. The pressure of the main lubrication oil circuits is supplied by the cycloid oil pump built in the speed-increasing gearbox, and driven by the low-speed shaft through direct connection. The perfect oil circuit testing system guarantees the pump’s long-term, safe, reliable running.

Safe, reliable and economical the Sundyne API 610, OH6, Integrally geared pump
API 610, 11th Edition OH6 Integrally Gear Driven Pumps are engineered for critical high-head, low-flow, heavy-duty services required by process and rotating equipment engineers within the hydrocarbon, chemical, petrochemical, power generation, gas production, and specialty processing industries. GSB-L1 oh6 pumps are renowned for high suction pressure and a wide range of operating temperatures.

Unlike conventional multi-stage pumps, our computer tailored hydraulics place the B.E.P. (best efficiency point) at the rated point resulting in optimum efficiency. An added benefit is reduced end-of-curve horsepower, allowing for smaller driver sizes resulting in energy savings.
