2,The system employs a CDLF pump as a feed pump, followed by a specially designed CDH high-pressure pump, providing technical excellence particularly suited for challenging high-pressure applications.
3,The CDH pump, a non-self-suction, vertical multi-stage centrifugal pump, is equipped with a standard motor directly coupled to the pump shaft. It features a robust design with tension rod bolts securing the pressure cylinder and overcurrent components between the pump head and the inlet/outlet sections. The innovative reverse flow channel design ensures reliability by aligning the pump's inlet and outlet along the same line and opposing the feed pump's rotation, thus only subjecting the pressure cylinder and mechanical seal to the outlet pressure of the feed pump.
