API610 Horizontal Centrifugal Multistage Circulation Pump

Fully compliant with the API 610-11th standard, the JHDK and JHDK-D series are multi-stage, axially split centrifugal pumps featuring dual-end support. To ensure a lower Net Positive Suction Head (NPSH), the JHDK-D model is engineered with a double-suction impeller at its first stage. Both suction and discharge flange dimensions adhere to ISO or ANSI specifications. The seal chamber architecture aligns with ISO21049/API682 criteria, while auxiliary piping for buffer, emergency cooling, heating, cooling, and flushing is configured per API plans. These pumps are extensively deployed across environmental protection projects, refined oil transport, boiler feedwater systems, metallurgy, mining, petroleum pipelines, petrochemical plants, and oil refineries. Furthermore, they function effectively as rich liquid and lean solution pumps in synthetic ammonia and fertilizer plants, as well as high-pressure hydraulic energy recovery turbines within the chemical sector.
