Slurry Pump Hi-Seal Expeller Parts

Sep 05, 2019

Nineteen years ago (1994) the Hi-seal™ expeller was designed with a larger diameter. The larger diameter enabled it to produce a slightly increased centrifugal force thereby a marginally higher head.

The larger diameter expeller was called a Hi-Seal™ expeller and a drawing from the IOM follows.

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.

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.
