STP Pump Installation Positions

The STP pump can be installed vertically, horizontally, upside-down and slanted.
However, it is recommended to mount the STP pump in the vertical position.
The STP pump may be inclined by its own weight in other positions in the case of
atmospheric release. To protect a structure for reduce vibration level, install prevention
measures for the inclination of the pump.
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 (see Figure 4.5).
This makes it possible to reduce the load on the magnetic bearing and the heat generated by
the STP pump.
