Scrapergate and Scrapergate Guide Installation Instructions
The scrapergate has been designed with an angle on each of its ends and a channel on the discharge
side for optimum performance and life span. It is used to separate the suction and discharge sides of
the pump. To ensure proper operation, it is essential that these installation instructions be followed
carefully.
The scrapergate has a suction side and a discharge side as shown in
Figure 8 . If viewed from the top,
the scrapergate is wider on the suction side than on the discharge side. One of the angled ends of the
scragergate has been stamped "SL" for suction left and the other has been stamped "SR" for suction
right. The scrapergate guide also has a suction side and a discharge side as shown in
Figure 9 . If
viewed from the end, the scrapergate guide has a rounded, wider section which corresponds to the
suction side and a thin, flat section which corresponds to the discharge side. The ends of the
scrapergate guide has also been stamped with the markings "SL" and "SR".
