JRG/JT Eductors/ et-Pumps are the most efficient way to pump manykinds of liquids and gases, and e en solids! "pplications aregenerally categori#ed as follows$ %iquid moti e pumping a liquid !&team moti e pumping a liquid ! %iquid moti e pumping a gas !

'ther application areas are in water treatment processes and in thosefor gases!

%iquid (oti e Pumping %iquid

Typical eductor applications include$

)raining sumps!

Pumping in areas where an electric pump would present an

e*plosion ha#ard!

+oosting the P& . et Positi e &uction ead of a pump!

Pulling an acid or 0ase into awater stream for dilution

purposes!

&team (oti e Pumping %iquid

1or draining sumps, where electrical lines are not a aila0le!

1or drawing water from ponds and warming it as it is 0eing

supplied to processes!

1or heating process fluids in-line!

1or cooking slurries in-line!

1or heating reactor 2ackets!

%iquid (oti e Pumping Gases

To aerate a liquid to reduce the +') .+asic '*ygen )emand of

5ater Jet Eductor

Principle of 'peration

1ig! 678, 1ig! 677 and 1ig! 679 5aterJet Eductors are designed for liquidpumping and mi*ing operations and forthe handling of some solids! :noperation, pressure liquid enters theeductor through the pressure no##le andproduces a high elocity 2et! This 2et

action creates a acuum in the line

which causes the suction liquid to flowup into the 0ody of the eductor whereit is entrained 0y the pressure liquid!

+oth liquids are thoroughly mi*ed inthe throat of the eductor and aredischarged against 0ack pressure! Thestreamlined 0ody permits the pressureliquid to mo e straight through theeductor and reduces the possi0ility ofsolids in the suction material fromcollecting and clogging!

1ig! 6789 "utomatic 5ater Jet Eductorsare used to pump out sumps .pits,tanks, etc! where liquid accumulatesslowly 0ut must 0e e acuated when itreaches a predetermined le el!'peration of the 1ig! 6789 "utomatic5ater Jet Eductor requires noelectrical connections or e*ternalpower other than moti e fluid!

1ig! 678, 1ig! 677 and 1ig! 679 5aterJet Eductors ha e a low initial cost,are self-priming, ha e no mo ing parts,are easy to install, require little orno maintenance, and pump as well as mi*liquids!

The 1ig! 6789 "utomatic 5ater Jet

Eductor is self-operated and requiresno electrical connections! The snap-action al e and 0all float are theonly mo ing parts! &pecial "utomaticEductors can 0e made from any other 2eteductors!
