★ General:
Type SPBB5, horizontal radial split casing multi-stage double casing centrifugal pump, is designed in accordance with API610 10th. It is ideal equipment for applications of petroleum and LPG in Petroleum Refineries, Petrochemical and Chemical factories, as well as other inflammable, explosive and toxic liquids without solids but in high temperature and pressure conditions.
★ Features:
● An upgraded new product from its original model transferred from Sulzer.
● Standard piping design in accordance with API610 and flange drilled to meet GB, DIN and ANSI Standards
● Bearing assembly constructed with advanced sliding and axial thrust bearings.
● High efficiency and energy-saving hydraulic models utilized for design of liquid contacted components, as a result efficiency increased by 3~5% than ordinary oil pumps.
● Configuration, dimensions and performance data shall be basically identical with its original type Y pumps.
● Pump components and spare parts highly interchangeable.
● Pump components materials can be selected from two standard Group II and III, more choices also available upon request for applications in cold and open locations and ocean vessels.
● All bearings shall be water cooled.
★ Piping System
Shaft stuffing box, bearing or pump frame shall be cooled with water according to medium temperature and pressure. Flow of cooling water in each pipe line is recommended within the range of 0.2~0.5 m3/h, and pressure 0.2~0.3Mpa. Sealing flush fluids vary according to operating conditions such as temperature and pressure etc.
Pressure differential between flushing fluid and stuffing box needs to be 0.07~0.1Mpa as a rule. In case of calorific medium, the differential shall be min. 0.175~0.2Mpa higher than the vaporizing pressure. Steam piping, around 0.1Mpa, shall be equipped when medium temperature tends down to crystallizing point.
