The SLM GV/HV Series represents Klaus Union’s advanced line of sealless multi-stage centrifugal pumps driven by maintenance-free synchronous permanent-magnet coupling. Available in barrel-type (GVxT), tension-rod (GV), or back-to-back (HV) configurations, it offers modular flexibility, supporting up to 15 stages, with the first stage optimized for low NPSH to enhance suction ability.
Operating across a wide spectrum—flow rates up to 300 m³/h, heads up to 2,200 m, temperatures from −120 °C to +350 °C, and pressures up to PN 250—the pump suits demanding industrial applications.
Its fully hermetic design, using a containment shell, eliminates shaft sealing issues and ensures zero leakage. Bearings made from silicon carbide, lubricated by the process fluid, offer a maintenance-free service life, while optional anti-friction bearings enhance endurance.
The SLM GV/HV pumps are engineered for critical process uses—pumping acids, bases, hydrocarbons, hot media, liquid gases, or toxic/odorous liquids—and offer a reliable, safe solution for operations requiring high system pressures with minimal maintenance.
