Product Introduction: The Series Single-Stage Chemical Pump is a high-performance, corrosion-resistant centrifugal pump designed according to international standards (ISO 2858). It is engineered specifically for the demanding task of transferring corrosive, abrasive, and hazardous liquids. Built from a selection of advanced alloys and materials, the Series ensures exceptional reliability, safety, and longevity in the most challenging chemical processing environments. Its robust construction and efficient hydraulic design make it the industry standard for handling acids, alkalis, solvents, and other aggressive fluids.
Operating Principle & Design: The pump operates on the principle of centrifugal force. Fluid enters the pump through the axial suction inlet and is drawn into the center of a rapidly rotating impeller. The impeller imparts kinetic energy to the fluid, forcing it outwards into the volute casing. The casing is designed to convert this high velocity into high pressure, expelling the fluid through the top-mounted radial discharge outlet.
The key to its “acid-resistant” capability lies in its material construction and sealing system.
- Wetted Parts: All components that come into contact with the pumped liquid—such as the casing, impeller, and shaft sleeve—are constructed from corrosion-resistant materials like Stainless Steel (SS304, SS316, SS316L), Duplex Stainless Steel, or other specialized alloys depending on the chemical concentration and temperature.
- Mechanical Seal: A critical component for preventing leaks of dangerous chemicals. The series can be fitted with various mechanical seal configurations (single, double, cartridge) and materials (e.g., Silicon Carbide, Tungsten Carbide, PTFE) to ensure compatibility with the specific fluid being handled.
Key Features & Benefits:
- Superior Corrosion Resistance: A wide range of material options allows for a custom-configured pump that can safely handle nearly any corrosive or chemical liquid.
- Standardized Dimensions: Designed to ISO 2858 standards, ensuring interchangeability with other compliant pumps and simplifying plant design and maintenance.
- Back Pull-Out Design: The entire bearing housing and rotating assembly can be removed for maintenance without disconnecting the pump casing from the pipework. This dramatically reduces downtime and simplifies repairs.
- High-Efficiency Hydraulics: The impeller and volute are optimized for maximum efficiency, reducing energy consumption and operational costs.
- Versatile Sealing Options: Can be equipped with different types of mechanical seals and flushing plans to guarantee leak-free performance, protecting both personnel and the environment.
- Robust Construction: Features a heavy-duty shaft and bearings to handle demanding operational loads, ensuring long service life.
Common Applications:
The Series pump is essential in a wide variety of industries, including:
- Chemical Manufacturing: Transfer of sulfuric acid, hydrochloric acid, nitric acid, caustic soda, and various solvents.
- Petrochemical Industry: Processing hydrocarbons and other corrosive byproducts.
- Pharmaceuticals: Handling pure and sterile process fluids.
- Metal Finishing & Electroplating: Circulating acidic and alkaline plating solutions.
- Food & Beverage: Pumping acidic liquids like citric juices or using aggressive CIP (Clean-In-Place) chemicals.
- Water Treatment: Dosing of chlorine, ferric chloride, and other treatment chemicals.
- Pulp & Paper: Handling chemical liquors and bleaching agents.
