QIS SERIES
Centrifugal Pump
INSTALATION
DESCRIPTION
Before servicing pump, disconnect electrical power source.
The QIS series closed-coupled pumps are made up of two sections, power or drive section and
the liquid end or pump section.
The pump is mounted to the frame of the drive motor by means of an adapter and is coupled to
the motor shaft. The impeller mounts on the stub shaft and is retained by one of the three methods.
The casing is fixed to the adapter with screws allowing to position the discharge outlet at 0°, 45°
and 90°. The internal, balanced mechanical seal (single or double) assures long seal life. The drive
motor is mounted on a frame having adjustable legs providing simple installation and leveling.
