AY Single Double Stage Oil Pump

Features:
● An upgraded new product from its original model transferred from Byron Jackson, USA.
● Renovated supporting frames with improved reliability.
● High efficiency and energy-saving hydraulic models utilized for design of liquid contacted pump components, as a result efficiency increased by 5~8% than original .
● Configuration, dimensions and performance data are basically identical with its original type. 
● Pump components and spare parts highly interchangeable between different models.
● 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.
● Air, fan and water cooling available for bearing cooling.

Piping System 
● Standard piping design in accordance with API610 and flange drilled to meet GB, DIN and ANSI Standards plans. 
● 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 vaporific medium, the differential shall be min. 0.175~0.2Mpa higher than the vaporizing pressure. Steam piping, around 0.1Mpa, shall be equiped when medium temperature tends down to crystallizing point.
