8. Install the pump end on the motor/drive magnet assembly.
Carefully slide the pump onto the drive magnet assembly.
See figure 7.
9. Secure the pump to the motor adapter flange (item 6) with
(4) motor adapter screws (item 8). Hand tighten screws be-
ing careful not to over tighten. See figure 8.

10. Rotate the motor fan or turn the impeller to ensure that there
is no binding in the pump.
11. Proceed to Installation Section.
Section II – Installation
Mounting
Motor feet should be securely fastened to a solid foundation.
Instructions for horizontal discharge installation:
Note: The pump ships from the factory so the discharge will be
in a vertical orientation. These instructions allow a horizontal
discharge.
1. Place the pump & motor in an upright position on the fan end
of the motor. Remove (8) housing screws (item 7). Pull the
housing away from the motor adapter / barrier (item 4) and
remove the o-ring (item 2). Reinstall the housing in the 3:00
position looking from the pump side. Note: O-ring will be
lubricated from the factory and should not require additional
lubrication. See figure 9.
2. Reinstall the o-ring onto the housing (item 1). If o-ring will
not stay in place it may be necessary to roll the o-ring under
when installing it on the housing. See figure 10.

3. Align the holes in the housing with the motor adapter /
barrier. Push the housing with o-ring in place straight down
to seat the o-ring. Hold the housing in place and reinstall the
(8) housing screws (items 7, 7A) in a star like pattern using

Piping
CAUTION: The NPSH available must be greater than the
NPSH required. Filters, strainers and any other fittings in the
suction line will lower the NPSH available and should be
calculated into the application.
• Install the pump as close to the suction source as possible.
• Support the piping independently near the pump to eliminate
any strain on the pump casing. In addition, the piping should
be aligned to avoid placing stress on the pump casing.
• The suction side of the pump should be as straight and short
as possible to minimize pipe friction.
• Keep bends and valves at least ten pipe diameters away
from the suction and discharge.
• The suction line should be at least as large as the suction
inlet port or one pipe size larger so that it does not affect the
NPSHa. Do not reduce the suction line size.
• The suction line should not have any high spots. This can
create air pockets. The suction piping should be level or
slope slightly upward to the pump.
• A check valve and control valve (if used) should be installed
on the discharge line. The control valve is used for regulating
flow. An isolation valves on both the suction and discharge
is used to make the pump accessible for maintenance. The
check valve helps protect the pump against damage from
water hammer. This is particularly important when the static
discharge head is high.
• If flexible hose is preferred, use a reinforced hose rated for
the proper temperature, pressure and is chemically resistant
against the fluid being pumped.
• The suction valve must be completely open to avoid restrict-
ing the suction flow.
• It is advisable to install a flush system in the piping to allow
the pump to be flushed before the pump is removed from
service.

the Phillips-head screwdriver. Hand tighten screws being
careful not to over tighten. See figures 11 & 12.
NOTE: Install two long screws (item 7A) inserting one on
either side of the discharge nozzle. See figure 12.
