Water Jet Eductors Bulletin 2M
Fig. 264 PVC and Kynar Water Jet
Eductors
Fig. 264 PVC and Kynar Eductors offer
resistance to many corrosive media. PVC
Eductors are not recommended, however, for
acetone, ketones, ether, esters, aromatic
hydrocarbons or chlorinated hydrocarbons.
A table of recommended uses is available on
request. Maximum temperature rating is
150°F. Kynar Eductors will handle PVC
applications including those mentioned
above. Kynar’s temperature limitation is
250°F. Pressure ratings are given in Table 2.
Fig. 264 PVC and Kynar Eductors operate on
the same principle as do all other S&K
Eductors. Performance characteristics with
water are shown in Bulletin 2M Supplement
Technical Data. For performance with other
liquids, contact S&K.
Nozzles and diffusers are not removable on
these eductors. Sizes 1” and smaller are of
molded construction.
