Figure 15 - 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.
