★ Overview
Series SPBB2 is horizontal between bearings radial-splitting double-volute single or two stage centrifugal pump. Two hydraulic models of high efficiency and anti-cavitation can be selected for the impeller depending on the operation condition so that it can be used for a wide range of operation conditions.
It complies with the design requirements in API 610 10th edtion and API 61011th edition. The product was designed by reference of the design and hydraulic performance of the most excellent similar products at home and abroad and by use of the advanced hydraulic model and strength analysis software. The strict international quality control system was applied in the process control of product to ensure that the overall performance of the product reaches the China-leading and world-advanced level.
★ Application range
Widely used for recovering excessive hydraulic pressure energy from petroleum refining, petrochemical, CTL, coal chemical, natural gas processing, polycrystalline silicon, plat forming, heating and other plants. It is typically used as hydraulic desulfurization and decarburization turbines in synthetic ammonia plants, hydraulic hydrogenation turbines in petroleum refining plants, hydraulic circulating water recovery turbines in polycrystalline silicon plants, turbine expansion engines in liquefied natural gas stations, hydraulic high-pressure water recovery turbines in sea water desalinization, etc.
