  • Sealless Magnetic Drive – Leak-Free & Maintenance-Optimized 
    The magnetic drive design eliminates mechanical seals, a common point of failure in traditional pumps. This ensures a safer, more reliable transfer of toxic, flammable, or reactive fluids. 
  • Premium Corrosion Resistance 
    Constructed with 316 Stainless Steel or Alloy C, with gears and bearings available in PTFE, Carbon, and high-performance thermoplastics, the SM935 is designed to handle aggressive chemicals, acids, and solvents with ease. 
  • Smooth, Quiet Operation 
    Helical gearing reduces noise levels by up to 10 dB, providing a quieter and more stable pumping process with minimal vibration and wear. 
  • Customizable Flow & Performance 
    Gear and bearing sets can be trimmed for optimized flow rates, allowing precision control for OEM applications and specialized systems. 
  • Wide Temperature Compatibility 
    Designed to function between -50°F and 450°F (-46°C to 232°C), making it suitable for thermal control systems and volatile fluid processing. 
  • Service-Friendly, Durable Design 
    Featuring a three-piece, thru-bolt housing with TFE-encapsulated silicone O-ring seals, the SM935 provides quick disassembly and long-lasting sealing performance. 
  • Versatile Global Integration 
    Standard 1 1/2" FNPT or BSPT ports and compatibility with both NEMA and IEC motor frames ensure easy installation and seamless retrofitting worldwide. 
  • Advanced Seal and Bearing Options 
    Available with Carbon, PTFE, or Rulon® bearings, and custom material combinations to match specific fluid handling needs. 
  • Fully Contained System Features 
    Equipped with recirculation heat ports, flush and drain connections, ensuring process safety, fluid purity, and system efficiency.
