Examples of liquefied gases for canned motor pumps :
- Ammonia (NH3)
- Butane (C3H8)
- Ethane (C2H6)
- Ethylene (C2H4)
- Propane (C4H10)
- Propylene (C3H6)
- Hydrogen sulphide (H2S)
Sealless Pumps for a Safer and Greener World
PUMPING RESTRICTIONS FOR LIQUIFIED GAS:
Pumping liquefied gas implies to have suitable solutions depending on the parameters:
OPTIMEX SOLUTIONS:
The canned motor pump technology is hermetically sealed due to its monobloc construction without dynamic sealing.
In case of stator liner rupture, the second containment eliminates all risks of leakage to the environment.
•  High vapor pressure or little pressure differences between vapor pressure and suction
pressure
•  Low available NPSH
•  High suction pressure
