CIXIMF 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 as a reasonable and standard-compliant solution. The following is a detailed analysis:

 

I. Core Parameter Matching Verification

 

Flow Rate and Head

Model Parameters: The rated flow rate of the 80CDL42-40 is 40 m³/h, and the head is 80 m (4-stage impeller, single-stage head approximately 20 m).

 

Requirement Matching: Fully meets the user's flow rate and head requirements, ensuring efficient system operation.

 

Power and Speed

Motor Configuration: 15kW-2P (AC380V 50Hz 3PH), speed 2900 rpm, protection class IP55, insulation class F.

 

Efficiency Analysis: Multistage pump efficiencies typically range from 65% to 75%. A 15kW motor can meet the 80m head requirement while providing sufficient margin to accommodate changes in system resistance.

 

Materials and Sealing: Flow-through components: SS304 stainless steel (impeller, guide vanes) + HT250 cast iron (pump body), highly corrosion-resistant, suitable for conveying clean water.

 

Sealing Type: Mechanical seal (silicon carbide/fluororubber material), reducing leakage risk and extending service life.

 

II. System Configuration Rationality Analysis

 

One Backup Design: Dual pump configuration: Two 80CDL42-40 pumps, automatically switching via a constant pressure unit (DN80-DN80/2HYD) to ensure continuous water supply.

 

Pressure Tank Function: A 100L pressure tank buffers system pressure fluctuations, reducing frequent pump start-stop cycles and extending the lifespan of the motor and mechanical seal.

 

PLC Control Panel Functions: Automation Control: Monitors parameters such as pressure, flow rate, and current; supports manual/automatic switching, fault alarms, and remote monitoring.

 

Energy-saving optimization: Automatically adjusts pump operation based on water consumption (e.g., single/dual pump switching) to reduce energy consumption.

 

Interface and installation: Inlet/outlet diameter: DN80 (80mm), compatible with system piping to reduce resistance loss.

 

Mounted base: Cast iron material, providing stable support and reducing vibration and noise.
