1、Introduction

HPA/HPB series petrochemical process pump is designed by referring to API610 the 10^th edition and API682 the 3^th  edition, and is a centrifugal volute pump with single stage, single suction and cantilever as well as axial suction, radial discharge design. The hydraulic balance can be kept by using front and rear wear ring and balance holes.Mechanical seal can be single end or double end banlanced cartridge type, and be equipped with cooling, washing or liquid-sealing system, the seal pipeline system is designed according to the API standards.Suction and discharge flanges are designed by HG, GB, DIN and ANSI standards.This pump is suitable to convey clean liquid or liquid with small amount of solid particles, or liquid in low/high temperature, or liquid chemically neutral/corrosive. It is mainly used in the industries of refineries, petrochemical,sea water desalination and coal processing, etc. the pump is characterized by safe and reliable operation, strong applicability and wide use range.

      HPB series pump is developed based on the our company’s HPA series petrochemical process pump to satisfy various high pressure and high temperature.

      HPA series pump max operating pressure 5.0MPa, max allowable inlet pressure 2.5 MPa. Range of operating temperature(-80~450)℃.

   HPB series pump max operating pressure 10.0MPa,max allowable inlet pressure 6.0MPa. Range of operating temperature (-80~300)℃.
