Eductors, Tank Liquid Agitators Jacoby-Tarbox Jet pumps JRG/JT

JRG/JT Eductors/Jet-Pumps are the most efficient way to pump many kinds of liquids and gases, and even solids. Applications are generally categorized as follows: Liquid motive pumping a liquid. Steam motive pumping a liquid. Liquid motive pumping a gas.

Other application areas are in water treatment processes and in those for gases.

Liquid Motive Pumping Liquid

Typical eductor applications include:

  • Draining sumps.
  • Pumping in areas where an electric pump would present an explosion hazard.
  • Boosting the NPSH (Net Positive Suction Head) of a pump.
  • Pulling an acid or base into awater stream for dilution purposes.

Steam Motive Pumping Liquid

  • For draining sumps, where electrical lines are not available.
  • For drawing water from ponds and warming it as it is being supplied to processes.
  • For heating process fluids in-line.
  • For cooking slurries in-line.
  • For heating reactor jackets.

Liquid Motive Pumping Gases

  • To aerate a liquid to reduce the BOD (Basic Oxygen Demand) of the fluid.
  • To exhaust vapors or gas from aroom.
  • To evacuate a vessel.
  • To scrub fumes from a gas.
  • To inject air, ozone, chlorine or other gas into a process liquid.
  • To create Vacuums

Steam Or Gas Motive Pumping Gases

  • To lower the boiling point of avessel, saving heating costs.
  • To produce a vacuum for filtration processes.
  • To prime pumps and vessels.
  • To prime siphon lines.

Mixing

  • To provide agitation of a vessel.
  • To control shear during agitation
