Nineteen years ago (1994) the Hi-sealu2122 expeller was designed with a larger diameter. The larger diameter enabled it to produce a slightly increased centrifugal force thereby a marginally higher head. <br>From the published test data at the slurry pumps best efficiency point, when running at a typical 700rpm for an 8/6 pump in a severe duty, there was about a 6kPa improvement in the maximum allowable suction pressure (66kPa rather than 60kPa). With many applications having an SG of about 1.3, this equates to a suction tank being able to have a maximum tank level of about 5.2m with a conventional style expeller instead of 4.7m. At higher speeds the expeller and impeller create even more head, with even less noticeable difference between the two expeller styles. <br><br>Where the difference was noticeable is when the slurry pumps were operating well below the pumps design flow (at about 20% of BEP) where slurry pumps do not usually operate due to increased wear.<br>Email: Sales2@tobeepump.com | Mob: 86-18031340097 | Fax: 86 311-87221317 | Skype: 8618031340097 <br>Web: www.tobeepump.com | www.slurrypumpsupply.com | www.tobee.cc
