Chemsteel - SM207 H - Hastelloy-C - Mag Drive

The Chemsteel™ SM207 MH Magnetic Drive Gear Pump is a robust, high-precision pump engineered specifically for transferring highly corrosive, hazardous, or ultra-pure liquids under pressure. Whether installed in chemical manufacturing facilities, laboratory pilot plants, or OEM systems requiring leak-free operation, this pump delivers reliable, quiet, and efficient performance in even the most demanding applications. 

Thanks to its sealless magnetic drive design, advanced material options, and customizable configuration, the SM207 excels in minimizing system contamination while maximizing safety and uptime. Designed with durability, ease of service, and global compatibility in mind, it’s an ideal choice for industries that can’t compromise on quality or performance. Additionally, CHEMSTEEL™ pumps offer bi-directional operation for applications requiring reversing flow.

    CHEMkit™ repair kits enable fast, affordable maintenance 
  • Designed for Precision and Performance
    Tolerances and material combinations ensure consistency and system protection 
  • Magnetic Drive Technology – Leak-Free & Safe 
    The sealless magnetic drive eliminates traditional shaft seals, removing one of the most common points of failure in pumping systems. Ideal for handling toxic, flammable, or reactive fluids without risk of leakage. 
  • Engineered for Chemical Resistance 
    Constructed from premium-grade 316 Stainless Steel or corrosion-resistant Alloy C, with internal components available in PTFE, Carbon, or advanced thermoplastics – ensuring compatibility with aggressive chemicals, solvents, and acids. 
  • Quiet and Smooth Operation 
    Precision-milled helical gears reduce noise levels by up to 10 decibels and deliver smoother fluid transfer with less vibration and wear. 
  • Custom Flow Optimization 
    Gear and bearing sets can be customized to “trim” performance characteristics, enabling fine-tuning of flow rates to meet OEM or specialized system requirements. 
  • High-Temperature and Low-Temperature Compatibility 
    Performs across a wide temperature range: from -50°F to 450°F (-46°C to 232°C), making it ideal for thermal control systems and volatile fluid processes. 
  • Rugged, Service-Friendly Design 
    Three-piece, thru-bolt housing with O-ring seals ensures easy disassembly, reliable sealing under pressure, and fast maintenance without the need for special tools. 
  • Versatile Motor Mounting Options 
    Compatible with both NEMA and IEC motor frames, with standardized 1/2” FNPT or BSPT ports and metric hardware – offering worldwide integration and straightforward retrofitting. 
  • Broad Seal and Bearing Options 
    Choose from carbon or PTFE bearings, and a range of mechanical, lip, or packing seals depending on media and pressure requirements. 
  • Fully Contained System Options 
    Includes ports for recirculation heat, flushing, and draining – enabling process safety and fluid purity in critical installations.
