Lhb No Leakage Chemical Process Centrifugal Pump

Engineered for safe, continuous transfer of aggressive process liquids, this chemical-process centrifugal pump uses a negative-pressure mechanical-seal system to minimize seal exposure to line pressure. When system pressure increases and flow falls during long-term operation, the negative-pressure device prevents the mechanical seal from bearing the full working pressure, significantly reducing leakage risk and extending seal life.

Key features

• Mechanical seal with negative-pressure device that isolates the seal from system pressure and reduces leakage risk
• Centrifugal pump design for stable flow and reliable operation in process environments
• Built for long-term transfer of corrosive and hazardous liquids where seal integrity is critical

Typical applications

• Alkali processing: soda ash, ammonia/brine solutions, caustic soda, chlorates and hypochlorites
• Acid handling: nitric, sulfuric, hydrochloric, phosphoric, acetic and other process acids
• Iron & steel: electroplating, pickling, waste-acid handling
• Nonferrous metallurgy: electrolytes (copper, nickel), zinc slurries, silver/gold leaching solutions, vanadium processing
• Pulp & paper: pulping liquors and bleaching liquors
• Fertilizer: urea and ammonium nitrate processing
• Petrochemical/refining: refinery process streams and alkylation intermediates

Benefits for industrial users

• Reduced environmental and process risk through improved sealing performance
• Lower maintenance frequency and longer mechanical-seal life compared with conventional seal arrangements
• Suitable for integration into chemical plants and industrial production lines where leak prevention is a priority
