1,Our dual pump system, combining CDLF and CDH in series, achieves impressive high pressure levels of up to 46 bar.
2,The system's first CDLF pump functions as a feed pump, while the second CDH pump, tailored for high-pressure scenarios, excels at its role. This document focuses on the technical specifications of the high-pressure pump.
3,The CDH pump is an exceptional, non-self-suction, vertical multi-stage centrifugal pump. It features a standard motor directly linked to the pump shaft via the pump head with a coupling. The pressure cylinder and overcurrent components are securely positioned between the pump head and inlet/outlet sections using tension rod bolts. The pump's inlet and outlet align perfectly at the base, and its rotation is counter to the feed pump. This reversed flow channel design ensures that the pressure cylinder and mechanical seal only experience the feed pump's outlet pressure, enhancing overall reliability.
