Canned Motor Pumps for safe, leak-free operations | PG Flow Solutions

Canned Motor Pumps

Fully enclosed, safe and long-lasting pumps which can be used for the most extreme applications and conveying hazardous media.

Hermetic canned motor pumps provide leak-proof and maintenance-free pumping for demanding industrial applications. The fully enclosed design eliminates mechanical seals and external lubrication systems, delivering long service life and high operational safety.

Complete reliability – even at the highest pressures and performance levels; they are used whenever conventional technologies reach their limits.

For reliable up-time in demanding applications and media

Applications

Hermetic pumps cover an extremely wide range of temperatures and are widely used in applications where containment and operational safety and reliability are key:

Carbon Capture & Storage - handling liquid CO2 at low temperatures
Oil & Gas processes requiring long service life, small footprint and low operating costs
Offshore Wind – reliable, seal-less operation for cooling circuits in unmanned or remote installations.
Marine - supporting shipowners transitioning to low-carbon sustainable fuels such as ammonia, ethanol and methanol with space-saving in-tank installations.
For Liquefied Natural Gas (LNG) or other cryogenic and low-temperature media.
Safe, leak-free transfer of other hazardous, toxic or aggressive media.
Suitable for extreme temperatures -120°C to +450°C

Why Hermetic

Hermetic pumps are engineered for applications where reliability and containment are critical. The seal-less, fully encapsulated construction ensures safe and efficient handling of aggressive, hazardous or valuable media — with minimal downtime and predictable OPEX.

Zero-leakage operation
No mechanical seals or couplings
Low-maintenance, long service intervals
Proven reliability in continuous duty environments
For high-vapour and high-pressure systems
