The DFCL and DFH pumps in series form a dual - pump system, capable of generating a high pressure of 46 bar.
The first DFCL pump is a feed - water pump, and the second DFH pump is a high - pressure pump specifically designed for high - pressure applications. This sample only provides the technical information of the high - pressure pump.
The DFH pump is a non - self - priming, vertical multistage centrifugal pump with a standard - mounted motor. The motor is directly connected to the pump shaft via a coupling on the pump head. Tie - rod bolts secure the pressure - resistant cylinder and wetted parts between the pump head and the inlet and outlet sections. The pump's inlet and outlet are in a straight line at the bottom of the pump. The pump rotates in the opposite direction to the feed - water pump, and the flow passage cavity is reversed, so the direction of the conveyed liquid is also reversed. This ensures that the pressure - resistant cylinder and mechanical seal only bear the outlet pressure of the feed - water pump, enhancing reliability.
