Introduction
The CYA Series Single Stage Horizontal Centrifugal Pump is a high-performance fluid handling solution engineered for industrial reliability and efficiency. Designed with a robust single-casing structure, this horizontal single-stage centrifugal pump features an innovative back-pull-out design, allowing for seamless maintenance of the impeller and shaft seal without disconnecting suction or discharge piping. This significantly minimizes operational downtime and labor costs.
Built to withstand demanding environments, it offers exceptional resistance to cavitation and low energy consumption. With versatile sealing options—including single, double, or balanced mechanical seals—and a wide range of material selections like SS304, SS316L, and Cast Steel, it ensures the safe transportation of both clean water and aggressive chemical fluids. Whether applied in industrial cooling, chemical processing, or urban water supply, the CYA series delivers stable performance under pressures up to 1.0 MPa and temperatures ranging from -10°C to +85°C. Trust our ISO-certified technology for your most critical fluid transfer needs.
Parts of the CYA Series Horizontal Single stage Centrifugal Pump
- The casing is cast as a single unit, consisting of the volute chamber, base, and inlet/outlet flanges; the inlet is axial, and the outlet is radial.
- The pump has a rear-opening structure, eliminating the need to disassemble the suction and discharge pipes for maintenance; the pump is directly driven by an electric motor or internal combustion engine (diesel or gasoline engine) via a flexible coupling.
- The pump’s shaft seal type is divided into packing type and mechanical seal type; the mechanical seal type includes three types: internal mechanical seal, external mechanical seal, and balanced mechanical seal. The balanced mechanical seal is used for pumps with operating pressures >1.6 MPa.
- The pump’s bearing lubrication methods include grease lubrication and oil lubrication.
- Bearing configuration of the suspension components.
High-Precision Impeller
- Features: Each impeller undergoes strict dynamic balance testing to ensure vibration-free operation. Available in closed types with multiple material options (SS304/SS316L/Cast Steel) to resist wear and cavitation.
- Description: The heart of the pump, designed with an optimized hydraulic model to maximize energy conversion.
Heavy-Duty Pump Casing
- Description: A single-casing horizontal volute design with integrated casting of the pump body and support feet.
- Features: The robust construction provides superior resistance against pipeline stress. The smooth flow channel design reduces friction loss and enhances overall hydraulic efficiency.
Reliable Shaft & Bearing Assembly
- Description: High-strength steel shaft supported by premium heavy-duty bearings.
- Features: Engineered for minimal shaft deflection, ensuring stable rotation even under high loads. This assembly extends the service life of both the mechanical seal and the motor.
Advanced Shaft Sealing System
- Description: Flexible sealing configurations based on your specific medium requirements.
- Features: Supports Single/Double Mechanical Seals (Balanced or Unbalanced) for leak-free chemical handling, or Soft Packing Seals for economical water supply maintenance.
Innovative Back-Pull-Out Bracket
- Description: A maintenance-friendly structural design that defines the CYA series.
- Features: Allows for the removal of the entire rotor assembly (impeller, shaft, and seals) for inspection without disturbing the suction or discharge piping, significantly reducing downtime.
Flexible Coupling
- Description: Connects the pump to the motor or diesel engine.
- Features: Compensates for minor angular and axial misalignments, absorbing start-up shocks and protecting the drive system from premature wear.
