Steam
Jet Ejectors

Steam jet ejectors are pumps that mix or compress different fluids together. The main components of the steam jet ejectors include – the nozzle, the suction and mixing chamber, and the diffuser.

What to expect

The Steam jet Ejectors have no moving parts and operate by the combined action of a high-pressure stream entraining the air, and other vapors (or liquids) at a lower pressure entering the moving stream. Once inside, they are then removed from the process system at an intermediate pressure, higher than the suction pressure but at times lower than the motive steam pressure.

IN ORDER TO ENSURE THE SPECIFIC FUNCTIONALITY, OUR STEAM JET EJECTORS HAVE THE FOLLOWING FEATURES MAKING THEM THE IDEAL CHOICE FOR CONTINUOUS PRODUCTION OF ECONOMICAL VACUUM CONDITIONS:
  • They handle wet, dry, or corrosive vapor mixtures well.
  • They are capable of developing specific vacuum conditions needed for industrial operations.
  • Different sizes are available to comply with any sized capacity requirements.
  • Their efficiency is above average.
  • They have no moving parts, therefore ensuring maintenance is low, and operation is fairly consistent even when corrosion is not a factor.
  • Quiet (or lower noise polluting) operation.
  • Stable operation within the specified design range.
  • Installation costs relatively low when compared to mechanical vacuum pumps.
  • Concise in size and therefore space requirements are minimal.
  • Simple operation and maintenance procedures.
