Product Overview
D Series Horizontal Multistage Centrifugal Pump is a horizontal segmented multistage centrifugal pump designed for high-head clean water delivery in industrial and municipal systems.
It addresses pressure instability, long-distance head loss, and staged pressure build-up requirements in boiler feed, mine drainage, and high-rise boosting systems.
It is applied in industrial water supply pipelines, municipal pressure transmission networks, boiler feedwater systems, and multi-stage high-lift transfer stations.
✔ For high-pressure clean water transmission systems requiring stable multistage head generation and continuous-duty reliability.
Model Designation
Applications
• Boiler feedwater systems under high-temperature preheated supply conditions
• Long-distance clean water transmission pipelines with staged pressure boosting
• Mine drainage systems requiring high head vertical lifting
• High-rise building water boosting with stable discharge pressure
• Municipal pressure transfer stations and regional water relay systems
Engineering Advantages
Segmented multistage casing structure distributes pressure across multiple impellers, ensuring stable head generation and structural stress balance under high working pressure.
Axial force balancing design reduces bearing load and improves long-term continuous-duty reliability.
Hydraulic channel optimized for high-efficiency multistage clean water transfer.
Mechanical seal or packing seal configuration adapts to various pressure and temperature conditions.
✔ Engineered for stable staged pressure build-up in high-head industrial water transfer systems.
System Components
D Series Horizontal Multistage Centrifugal Pump mainly consists of:
• Pump casing segments
• Multistage impellers
• Pump shaft
• Balance disc or balance drum assembly
• Bearing housing
• Shaft seal assembly
• Coupling

How to Select a Pump Model
Determine required flow rate and total dynamic head including pipeline friction and elevation difference.
Confirm liquid temperature and medium characteristics to select sealing configuration.
Evaluate continuous-duty operating time and load profile.
Check system maximum allowable working pressure against casing rating.
✔ Model selection shall be based on actual duty point and hydraulic performance curve matching.
Engineering Notes
The segmented casing design facilitates staged pressure distribution.
Balance disc structure compensates axial thrust under high head operation.
Bearing configuration supports high-speed multistage rotation.
Suitable for horizontal installation with rigid base alignment.
Compliance & Quality Assurance
• Hydraulic performance test in accordance with ISO 9906
• Pressure casing strength test
• Rotor dynamic balance test
• Material traceability for pressure-bearing components
• Optional third-party inspection certification
Safety Notice
• Do not operate under dry-running condition
• Ensure proper alignment before coupling startup
• Do not exceed rated working pressure
• Disconnect power before maintenance
OEM & Customization
This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.
Available options include:
• Motor voltage & frequency
• Mechanical seal type and configuration
• Wetted parts material selection
• Surface coating and corrosion protection
Configuration is determined based on duty point and project specifications.
FAQs
Q1: Can the pump operate under VFD control?
Yes, operation under variable frequency drive is permitted within rated speed limits.
Q2: What is the allowable working pressure?
Maximum working pressure depends on stage configuration, up to 8.0 MPa.
Q3: What sealing options are available?
Mechanical seal and packing seal configurations are available.
Q4: What standards does the pump comply with?
Hydraulic testing complies with ISO 9906.
Q5: Is the pump suitable for hot water applications?
Standard type supports ≤ 80°C; high-temperature versions require specific configuration.
Q6: How is axial thrust balanced?
Axial thrust is balanced through balance disc or drum assembly.
