No Leakage Multistage Magnetic Pump

A sealless, multistage magnetic-drive centrifugal pump engineered for transporting corrosive or hazardous liquids at small to moderate flow rates and high discharge heads. The magnetic drive eliminates dynamic shaft sealing and the associated leakage risk, making this pump suited to petrochemical, chemical, electroplating, pickling, and other industrial processes that require zero-leak containment.

Key features

• Sealless magnetic drive: fully isolated pumped fluid path with magnetic coupling to eliminate shaft seals and potential leaks.
• Multistage design: engineered for high head with compact footprint; magnetic circuit and hydraulic layout minimize axial load and maintain stable performance under high power and pressure.
• Material flexibility: flow-path components (pump casing, inner rotor, cover, impellers, isolation sleeve, shaft) can be produced in stainless steels (304, 316, 316L), 904L, TA2 (titanium), Hastelloy C276 and other corrosion-resistant alloys via precision casting to match process chemistries.
• Wear & bearing materials: moving rings, shaft sleeves and sliding bearings available in crystalline silicon carbide, tungsten carbide or similar high-wear, high-temperature ceramics for long service life and corrosion resistance.
• Standards-based design: developed in accordance with HGT2730-2012 (magnetic-driven centrifugal chemical process pumps) and API 685 principles for sealless centrifugal pumps.

Typical applications

• Petrochemical and refining processes
• Chemical manufacturing, acid and alkali handling
• Electroplating, electrolysis and surface treatment lines
• Pickling, dyeing, pesticide and pharmaceutical production
• Rare-earth and metal processing, smelting
• Paper mill and specialty process fluids where containment and corrosion resistance are required

Performance range (typical)

• Design pressure: 1.6 MPa to 6.3 MPa
• Flow rate: 3 m3/h to 155 m3/h
• Head (lift): 20 m to 603 m
• Motor power: 5.5 kW to 315 kW
• Service temperature: -60 °C to 300 °C (with special materials, up to 450 °C)

Why specify this pump

• Zero-leakage operation reduces environmental and safety risks and lowers total cost of ownership in hazardous service.
• Material options and robust wear parts allow tailoring to aggressive chemistries and higher temperatures.
• Multistage magnetic configuration gives high head capability in a sealless package, suitable for demanding process applications.

For procurement, specify required wetted materials, maximum temperature, required flow/head point, and any special certification or testing needed (e.g., hydrostatic test pressure) so the pump can be configured to your process requirements.
