HWBZ 220V Explosion-Proof Centrifugal Pump – Technical Description The HWBZ 220V explosion-proof centrifugal pump is a robust and reliable industrial pump designed for handling flammable, explosive, or hazardous liquids in high-risk environments. Engineered to meet stringent safety standards, this pump ensures efficient fluid transfer while minimizing ignition risks in volatile atmospheres. Key Features 1. Explosion-Proof Design - The pump is constructed with explosion-proof materials and components, including a certified motor enclosure that prevents sparks or excessive heat from igniting surrounding gases or vapors. - Complies with international explosion-proof standards such as ATEX, IECEx, or NEC/CEC, ensuring safe operation in Zone 1 or Zone 2 hazardous areas. 2. 220V Single-Phase Motor - Powered by a 220V, 50/60Hz single-phase motor, the pump is suitable for standard industrial power supplies, offering easy integration into existing systems. - The motor features thermal overload protection and high-efficiency insulation to withstand demanding operating conditions. 3. Centrifugal Pump Mechanism - Utilizes a centrifugal impeller for smooth, high-flow liquid transfer with minimal pulsation. - Capable of handling clean or slightly contaminated fluids, including water, oils, solvents, and certain chemicals, depending on material compatibility. 4. Durable Construction - Pump casing and impeller are made of corrosion-resistant materials such as stainless steel, cast iron, or engineered plastics (e.g., PP, PVDF) for longevity in aggressive environments. - Mechanical seals or gland packing options ensure leak-free performance and reduce maintenance needs. 5. Performance Specifications - Flow Rate: Adjustable based on impeller design, typically ranging from 5 m3/h to 100 m3/h. - Head Pressure: Up to 50 meters, customizable for specific applications. - Temperature Range: Suitable for fluids from -20°C to +120°C, with optional high-temperature adaptations. 6. Safety & Reliability - IP65 or higher ingress protection guards against dust and water splashes. - Anti-vibration design reduces noise and wear, extending service life. Applications - Oil & Gas: Transferring fuels, lubricants, or wastewater in refineries. - Chemical Processing: Handling corrosive or volatile liquids. - Pharmaceuticals: Safe conveyance of solvents in controlled environments. - Mining & Wastewater: Dewatering or slurry transport in hazardous zones. Advantages - Low maintenance due to rugged design and high-quality materials. - Energy-efficient operation reduces long-term costs. - Versatile for diverse industries requiring explosion-proof solutions. This pump combines safety, durability, and performance, making it an ideal choice for hazardous-duty fluid transfer applications.
