Cpn Corrosion Resistant Alkali Liquid Transfer Pump

Robust, corrosion-resistant centrifugal transfer pump engineered to handle alkali liquids — including fluids that contain solid particles or are prone to crystallization. The pump combines high hydraulic efficiency with anti-clogging design and easy maintenance to meet the demands of chemical, petrochemical and water treatment processes.

Key features

• Engineered for alkali and crystallizing liquids and slurries; suitable for abrasive and corrosive media.
• Corrosion-resistant construction and efficient hydraulics for low energy consumption.
• Open impeller design minimizes clogging risk.
• Back-door inspection/maintenance cover allows removal of the impeller and shaft seal without disassembling the pipeline or motor, reducing downtime.
• Axial clearance adjustment mechanism compensates for wear and preserves pump performance over time.
• Cast foot support on the pump body protects bearings and mechanical seals from pipeline loads.
• High-rigidity, precision-machined shaft and oil-lubricated bearings with visible oil-level indicator for reliable operation.
• Seal options: packing seal or single/double mechanical seal; available in balanced, non-balanced, internal or external arrangements.
• Optional cooling water device for handling higher-temperature liquids.
• Drive options: standard Y-type motor or YB explosion-proof motor.
• Pump rotation: clockwise viewed from the driving end.

Performance specifications

• Flow rate (Q): 1.6 to 400 m3/h
• Head (H): 5 to 125 m
• Maximum working pressure: ≤ 1.6 MPa
• Working temperature: 20 to 150 °C

Typical industries and applications

• Chlor-alkali and soda production
• Chemical fertilizers, pesticides and general chemical processing
• Pharmaceuticals and dye manufacturing
• Petrochemical and chemical fiber plants
• Pulp & paper and wastewater treatment
• Environmental engineering and industrial water systems

Operational advantages

• Designed for straightforward field maintenance and long service life in corrosive alkali environments.
• Flexible seal and balance configurations allow selection based on process requirements.
• Suitable for installation where minimizing downtime and avoiding clogs are priorities.

For specification matching and selection, provide required flow, head, fluid characteristics (composition, solid content, temperature) and site constraints (available motor, explosion-proof requirements, piping loads).
