    Product information

     What is a Single-Stage Pump?

    • Definition: A centrifugal pump that uses a single rotating impeller to move fluid through the casing.
    • Key Principle: Centrifugal force pushes liquid outward from the impeller center, creating pressure at the discharge.
    • Design Benefits: Compact, easy to maintain, lower purchase cost compared to multi-stage pumps.

     Types of Single-Stage Pumps

    Type Characteristics Typical Applications
    End Suction Pump Fluid enters axially, exits radially; most common type Water transfer, HVAC, irrigation
    Inline Pump Suction and discharge on same axis; space-saving Piping systems, building circulation
    Self-Priming Pump Removes air from suction line automatically Sumps, above-tank installations
    Magnetic Drive Pump No mechanical seal, zero leakage Toxic or corrosive fluids
    Close-Coupled Pump Motor and pump share one shaft; compact Tight installations, small systems
    Double Suction Pump Fluid enters impeller from both sides; balanced forces Large flow, municipal water supply

     Technical Specifications

    • Flow Rate: Up to 2,000 m³/h
    • Head: Up to 100–150 m
    • Efficiency: 70–88%
    • Materials: Cast iron (general service), stainless steel (SS304/SS316 for chemicals)
    • Motor Power: Typically up to 2 MW depending on size
    • Temperature Range: –20 °C to 200 °C

     Applications

    • Water Supply & Irrigation: Municipal distribution, agricultural irrigation.
    • HVAC Systems: Chilled water and hot water circulation.
    • Cooling Towers: Industrial cooling water circulation.
    • Fire-Fighting Systems: High-volume water delivery.
    • Chemical & Petrochemical: Corrosion-resistant designs for chemical transfer.
    • Mining & Metallurgy: Dewatering, slurry transfer.
    • Pulp & Paper Industry: Continuous process pumping of clean or fiber-laden liquids.
