Fig. 254 Eductors Using Liquid in Handling Dry Solids for handling liquid solids, also known as Hopper Eductors are designed to obtain efficient liquid to solids entrainment ratios and maximum discharge pressure capabilities. The Fig. 254 Hopper Type Eductor is made for handling slurries or dry solids in granular form and are used extensively for ejecting sludges from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials. Agitating jet washdown nozzles keep the material from adhering to the sides of the hopper and keep it moving down into the eductor. Pressure water, passing through the eductor nozzle, entrains the sand, sludge, or other materials and discharges into the piping system. Standard Fig. 254 Eductors are made in cast iron and have hardened steel nozzles and throat bushings. Special materials are also available on order. The nozzle and throat are both easily replaced.
