Jiangsu Haishi Pump Manufacturing Co., Ltd.

Haishi’s company history traces the business to 1977 and describes the combination of a Shanghai pump-factory petrochemical division with Jiangsu Xinya Chemical Machinery. Its manufacturing description includes casting, machining, sheet-metal work and pump assembly, together with testing and physical-chemical inspection facilities. These are company-published capabilities rather than an independent audit of the plant.

The catalog spans several operating duties instead of a single general-purpose pump. HCZ covers horizontal chemical-process service, while the HXK and circulation families address different pressure or circulation requirements. The HCZ page below separates the series operating envelope from individual speed and impeller selections. Buyers comparing this supplier should match fluid properties, materials, seal arrangements and the requested operating point to a specific configuration.
