Ethanol
Hydrocarbons (fuels)
Amine/Water Mixtures
Water
Sea Water
Glycol
Other coolant mixtures

Typical use cases include:

Methanol / Ammonia Fuel Supply System
Methanol / Ammonia Transfer
Methanol / Ammonia Bunkering
Methanol / Ammonia Production (Power-to-X)

Magnetically driven centrifugal pumps meet the requirements for:

Leak Prevention
High efficiency
Reduced Friction
Improved Reliability
Low Maintenance
Installation and serviceability
Energy Efficiency
Enhanced Safety
Environmental Benefits

Design Features

Magnetic Drive pumps use magnetic coupling to avoid leakage. By eliminating the need for expensive auxiliary shaft seal flush systems and minimising operational downtime for seal inspections or replacements, we provide a comprehensive solution that aligns with both safety and sustainability. With its compact design and small footprint, this pump offers convenient and flexible installation, particularly in enclosed spaces.

Why choose magnetic drive?

100% seal-less design – no leakage, no emissions
Ideal for toxic, hazardous, flammable, or valuable liquids
No seal system maintenance – reduced downtime and lower operating costs
Proven, reliable and efficient alternative to conventional shaft seal pumps
