Principle of Operation

Fig. 224 Water Jet Sand and Mud Eductors are used in pumping out wells, pits, tanks, or sumps where there is an accumulation of sand, mud, or other material not easily handled by the standard eductor. They are ideal for handling the heavy sludge residue from refining operations. A high pressure liquid produces a high velocity jet that entrains the suction material. This mixture is then discharged through a vertical pipe.

Fig. 225 Sand and Mud Syphons are also designed for pumping out pits and receptacles where there is an accumulation of sand, mud, sludge, or similar materials. The Syphon is submerged in the material being handled which it entrains and discharges vertically. A high pressure gas produces a high velocity jet than entrains the suction material. This mixture is then discharged through a vertical pipe.
