Advanced Multi-Stage Side-Channel Pumps with Magnetic Coupling
When safety, performance, and durability are mission-critical in fluid handling applications, Klaus Union SLM SV Magnet Drive Pumps provide a reliable and leak-free solution. Developed in accordance with DIN EN ISO 15783, this pump series combines multi-stage side-channel hydraulics with hermetic magnetic drive technology, offering optimal performance for industries requiring safe, sealless, and self-priming pumping.
This series is engineered for applications involving high differential head, gas-laden liquids, interrupted suction, and aggressive or hazardous fluids. Whether in the chemical industry, power generation, cryogenics, or cooling circuits, the SLM SV’s robust modular design and material flexibility provide unmatched operational safety and efficiency.
Technical Excellence in Every Detail
The SLM SV features a multi-stage design (up to 8 impellers), delivering heads up to 470 meters, while maintaining flow rates up to 42 m³/h. A low-NPSH first-stage impeller enables effective self-priming, ideal for situations where suction interruptions or vapor-laden liquids are common.
The magnetically coupled drive system completely eliminates dynamic shaft seals—removing any risk of leakage. With single or double containment shells, optional leak monitoring, and explosion-proof bearing brackets, safety is engineered into every aspect of this pump.
Thanks to a wide selection of premium materials—from duplex stainless steel, DLC-coated impellers, to non-metallic and ceramic containment shells, along with silicon carbide bearings—the SLM SV is built to withstand corrosive, toxic, and high-temperature fluids up to +250 °C, and system pressures up to PN 400.
Available in close-coupled (SVB) or bearing-supported (SVN, SVS, SVO) configurations, it can be adapted to a broad range of installations.
Conclusion
The Klaus Union SLM SV represents the pinnacle of magnet drive pumping systems, built for demanding process conditions and hazardous fluids. With its superior engineering, modular flexibility, and zero-leakage operation, it provides long-term value and safety assurance across many industries.
