Stp Pump Installation Positions; Positions Of The Outlet Port On The Horizontally Or Slanted Installed Stp Pump - Edwards STP-XF803 Series Instruction Manual

2.3.2

STP pump installation positions

The STP pump can be installed vertically, horizontally, upside-down and/or slanted. (Depending
upon the pump model, the STP pump cannot be installed in some positions. Refer to "TECHNICAL
DATA" in the STP Pump Instruction Manual (B).)
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.
