The Klaus Union SLM AP Series is a single-stage, horizontal, API 685-compliant magnet drive pump —specifically engineered for continuous industrial service handling toxic, aggressive, flammable, or high-temperature fluids. Its sealless design ensures absolute fluid containment, eliminating leakage risks and extra seal systems. With no dynamic seals, maintenance is minimized.
Key technical advantages include:
-
Permanent magnetic drive delivers hermetic sealing and maintenance-free operation
-
Modular V‑Concept architecture enables fast customization and reduced spare part variety
-
Robust construction with high-grade materials—steel, stainless, duplex, Hastelloy C, titanium
-
Thermal control jackets protect and regulate fluid and bearing temperatures
-
Dual design options: close-coupled for compact installations or bearing-supported for heavy-duty applications
-
High operational specs: 3,500 m³/h, 220 m head, -120 °C to +450 °C, PN 400
-
Efficient containment shell options lower eddy-current losses, improving system efficiency
Ideal for petrochemical, refinery, gas processing, and energy sectors, the SLM AP combines API 685-level reliability, leak-free safety, and service-free magnet drive efficiency.
