Allweiler SN-M Three Screw Pump with MagDrive

The Allweiler SN-M is a three screw rotary pump with magnetic drive (MagDrive) designed for operating pressures up to 64 bar. Based on the proven Allweiler SN series, the SN-M combines the smooth, low pulsation performance of three-screw pump technology with the benefits of a sealless magnetic coupling, eliminating the need for a conventional shaft seal.

The SN-M is particularly suitable for applications involving toxic, environmentally hazardous, highly volatile, or explosive liquids, where leakage prevention is critical. In addition, it can handle all non-abrasive liquids typically pumped by the standard Allweiler SN series.

Suitable Fluids

The SN-M is designed for handling:

• Toxic liquids
• Environmentally dangerous liquids
• Highly volatile liquids
• Explosive liquids
• Fuel oils
• Lubricating oils
• Hydraulic oils
• Cutting oils
• Coolant oils
• Cooling oils
• Waxes
• Polyols
• Isocyanates
• Paints and lacquers
• Other non-abrasive liquids fitting for the SN series

Typical Applications

The Allweiler SN-M provides leak-free pumping of hazardous and valuable process liquids in industrial, chemical, and marine applications where environmental protection and working safety are essential.

Common applications include:

• Chemical processing
• Petrochemical installations
• Marine and Offshore engineering
