Figure 4.3 STP Pump Installation Positions
When installing the STP pump in a horizontal or slanted position, it is recommended to
install it so that the direction of the outlet port is on a vertical or horizontal plane in the
direction of the gravity.
This makes it possible to reduce the load on the magnetic bearing and the heat generated by
the STP pump.
