Adjusting the shaft
It is important that dimension X is correct to achieve efficient pumping.
Note: Dimension X in all pumps may be measured as below. However, the structure
of the SPS 100 pump casing is different from other models (and not as shown here)
and SPS 100 dimension X is adjusted differently. SPS 100 pumps must be returned
to MasoSine for dimension X adjustment.
