Vertical Multistage Centrifugal Pump

Regarding your requirements for selecting a CIXIMF vertical multistage centrifugal pump (medium: water, flow rate: 40 m³/h, 

head: 80 m, 2 pumps, one for standby, with pressure tank and PLC control panel), our technicians recommend the 80CDL42-40 

vertical multistage centrifugal pump, which fully meets the standard parameter requirements and has a reasonable configuration. 

The specific analysis is as follows:

I. Core Parameter Matching

* Flow Rate and Head

The rated flow rate of model 80CDL42-40 is 40 m³/h, and the head is 80 m, which perfectly matches your requirements.

This pump adopts a multistage impeller design, with a single-stage head of approximately 20 m (total head = single-stage head × number 

of stages, here 4 stages), stably achieving the required 80 m head.

* Power and Efficiency

The matching motor has a power of 15 kW and a speed of 2900 rpm, which meets the high-efficiency operating range (multistage pump 

efficiency is typically 60%-80%). The motor has an IP55 protection rating and an insulation class of F, making it suitable for industrial

 environments, energy-efficient, and safe.

Materials and Sealing: The flow-through components are made of SS304 stainless steel and HT250 cast iron, offering strong corrosion

 resistance and suitability for conveying clean water.

The mechanical seal design reduces leakage risk, extends service life, and lowers maintenance costs.

II. System Configuration Rationality: One-for-One Backup Design: Two pumps are configured as backups for each other, ensuring

 continuous system operation and preventing downtime due to single-unit failure.

The constant pressure unit DN80-DN80/2HYD can automatically switch between primary and backup pumps to maintain stable pressure.

Pressure Tank and PLC Control: A 100L pressure tank buffers system pressure fluctuations, reducing frequent pump starts and stops and 

extending equipment life.

The PLC control panel enables automated operation, monitors parameters such as pressure and flow, supports remote control, and

 improves management efficiency.

Interfaces and Installation: 80mm (DN80) inlet and outlet diameters match the system piping, reducing resistance loss.

The cast iron mounting base provides stable support and reduces vibration and noise.

III. Summary of Selection Advantages

Parameters/Configuration 80CDL42-40 Solution Standard Requirements Matching Results

System Configuration One Backup + Pressure Tank + PLC One Backup + Automated Control Fully Meets Requirements

IV. Recommendations and Actions

Confirm Details: It is recommended to further communicate with technical personnel to confirm details such as flange standards

 (e.g., GB/T 9119), motor brands (e.g., Siemens, ABB), etc.

Quotation and Delivery: Contact CIXIFM (Email: mailto:sales01@cxflowmeter.com; WhatsApp: +86 180 4984 1995) for a detailed

 quotation and delivery timeline.

Installation and Commissioning: Ensure installation is performed by a professional team, and test system pressure stability and

 PLC control logic.

Conclusion: The 80CDL42-40 vertical multistage centrifugal pump meets the requirements in terms of parameters, configuration, 

and reliability, making it an efficient and economical choice.
