CDL Vertical Multistage Centrifugal Pump

The CDL series is a vertical multistage centrifugal pump equipped with a standard motor as standard. The motor shaft is directly connected to the pump shaft via a coupling at the pump head. The overall structure uses tie rod bolts to securely fasten the pressure-resistant cylinder and flow components between the pump head and the inlet/outlet sections. The inlet and outlet ports at the bottom of the pump body are aligned on the same straight line. This pump can also be optionally equipped with an intelligent protector to effectively prevent faults such as dry running, phase loss, and overload.

Vertical multistage centrifugal pumps are an efficient and economical solution for “high head, low flow, and small space” applications. It mainly provide stable and high-head power for fluids.

Through the series connection of multiple impellers, they can generate pressure far higher than that of single-stage centrifugal pumps even at relatively low flow rates, making them suitable for scenarios where liquids need to be transported to high elevations or where high system pressures need to be overcome. Furthermore, the output flow is smooth and continuous, with minimal pulsation.

Working Principle

The working principle of the Vertical Multistage Centrifugal Pump is as follows: the motor drives the shaft to rotate multiple series-connected impellers at high speed. The fluid passes through each stage of impellers and guide vanes in sequence. In each stage, the rotating impeller transfers centrifugal force to the fluid, causing its kinetic energy and pressure energy to increase progressively. Finally, after being pressurized through multiple stages, the fluid is discharged vertically under the collection and straightening of the final-stage guide vanes.

Application

CDL is a versatile product capable of conveying various media ranging from tap water to industrial liquids, suitable for different temperature, flow rate, and pressure ranges. CDL is designed for non-corrosive liquids.
