East Dfcl+Dfh High-Pressure Dual Pump Centrifugal Pump Water Pump

• 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.

Performance curve description

• All curves are based on measurements with the motor at a constant speed of 2900rpm or 2950rpm.
• Curve tolerances comply with ISO9906: 2012, 3B grade.
• The test uses water without air at 20°C with a kinematic viscosity of 1mm²/s.
• Select the pump within the reference performance range to prevent overheating due to low flow or motor overload due to high flow.
