Introduction
The ChangyuPump horizontal centrifugal water pump is built based on ISO 2858 dimensional standards and JB/T53058-93 pipeline pump specifications, ensuring full compatibility with international piping systems and easy equipment replacement. Its back pull-out structure allows maintenance without dismantling pipelines, significantly reducing downtime in continuous operation environments such as factories and municipal systems. The three-direction outlet configuration further improves installation flexibility in space-limited projects.
This horizontal centrifugal pump is engineered for clearly defined fluid conditions, including clean water, ≤120°C hot water systems, and non-solid corrosive media. It is widely deployed in HVAC circulation loops, industrial cooling systems, building pressure boosting, and long-distance water transfer. With standardized design and application-specific variants, it serves as a practical and reliable solution for engineers requiring stable performance under controlled operating parameters.
Components and Functions of Horizontal Centrifugal Water Pump
Horizontal centrifugal water pump parts primarily include the impeller, casing, shaft, bearings, and sealing assembly. Please see the following diagram of the Horizontal Centrifugal Water Pump for details:
- Outlet Configuration (Multi-Directional)
The discharge outlet can be installed in left, right, or upward directions, providing flexible installation options for different pipeline layouts. - Impeller (Closed-Type Design)
The impeller is the core hydraulic component, responsible for generating centrifugal force to achieve the required flow rate and head. Precision dynamic balancing ensures stable operation and reduces vibration. - Pump Casing (Volute Type)
Designed according to ISO 2858 standards, the casing converts fluid velocity into pressure while providing strong structural support under system pressure up to 1.6 MPa. - Pump Shaft
High-precision machined shaft ensures excellent concentricity, minimizing mechanical loss and maintaining stable transmission between motor and impeller. - Mechanical Seal System
Equipped with hard alloy mechanical seals (optional silicon carbide or titanium alloy), enabling leak-free operation under temperatures up to 120°C and various liquid conditions. - Bearings (Heavy-Duty Support)
High-quality bearings reduce friction and support continuous operation, ensuring low noise (<40 dB) and extended service life. - Motor (B35 Standard Direct-Coupled Motor)
The pump adopts a direct-coupled motor structure, eliminating the need for alignment adjustment after installation and improving overall transmission efficiency. - Base Frame
Integrated base ensures structural stability, reduces vibration transmission, and simplifies installation in industrial and municipal systems. - Outlet Configuration (Multi-Directional)
The discharge outlet can be installed in left, right, or upward directions, providing flexible installation options for different pipeline layouts.
Working Principle
Centrifugal pumps function by transforming mechanical rotation into fluid pressure and flow. As the impeller spins rapidly within its casing, it creates centrifugal force that accelerates the water radially outward. This high-velocity flow is then directed through a gradually expanding volute casing, where its speed is converted into stable pressure, efficiently discharging the liquid through the outlet pipeline.
- Motor Drive (Mechanical Energy Input)
The B35 standard motor provides direct rotational power to the pump shaft, eliminating coupling misalignment and ensuring stable energy transmission under continuous operation conditions. - Impeller Rotation (Centrifugal Force Generation)
As the impeller rotates at high speed, it accelerates the liquid outward from the center, creating centrifugal force that continuously draws fluid into the pump inlet. - Energy Conversion (Velocity to Pressure)
The high-velocity liquid is guided into the volute pump casing, where kinetic energy is gradually converted into static pressure, ensuring stable and controlled flow output. - Flow Direction Control (Continuous Discharge)
The pressurized liquid is smoothly discharged through the outlet pipeline, maintaining steady flow for systems such as water supply, HVAC circulation, and industrial transfer applications. - System Stability (Low Vibration Operation)
Precision-balanced impeller design and high concentricity shaft structure ensure smooth hydraulic operation, reducing vibration and noise during long-term continuous working cycles.

CYW Series Model Code Interpretation (Pump Selection Guide)
The CYW series horizontal centrifugal water pump adopts a structured model coding system to clearly define pump size, hydraulic performance, and impeller trimming status. This coding method helps engineers quickly identify pump specifications and select the correct configuration based on system requirements.
Example Model: CYW100-160(I)AB
- CYW → Horizontal single-stage single-suction centrifugal water pump
- 100 → DN100 mm inlet/outlet diameter
- 160 → 160 mm original impeller outer diameter
- (I) → Flow classification group I
- A → First impeller trimming applied (performance adjustment)
- B → Second impeller trimming applied (fine adjustment)
Interpretation Result:
This model represents a DN100 horizontal centrifugal water pump with a 160 mm impeller, which has undergone two-stage impeller trimming to precisely match system flow and head requirements. It is suitable for applications requiring customized hydraulic performance such as HVAC circulation, industrial water transfer, and municipal boosting systems.
