READ THESE INSTRUCTIONS CAREFULLY BEFORE
ATTEMPTING TO INSTALL, OPERATE, OR SERVICE

LIMITATIONS, AND POTENTIAL HAZARDS. PROTECT
YOURSELF AND OTHERS BY OBSERVING ALL SAFETY
INFORMATION. FAILURE TO COMPLY WITH THESE
INSTRUCTIONS COULD RESULT IN PERSONAL INJURY AND/

SAFETY GUIDELINES
WARNING: To reduce the risk of electrical shock, remove the pump
from power before attempting to service or remove any part.
Read all instructions and safety guide lines thoroughly. Failure to
follow the guidelines and instructions could result in serious bodily
in jury and/or property damage.
Do not pump flammable liquids such as gasoline or fuel oil.
Make sure pump is grounded.
During operation, the area surrounding the pump may be covered
with water; take care when handling the pump.
Do not disconnect plumbing connections when pump is in operation.
Do not stand in water when changing fuses.
PUMP CONSTRUCTION
The patented magnetic drive pump design consists of a cylindrical
drive magnet attached to the motor shaft, which rotates around a
chemical-resistant plastic separator housing. Inside this housing is a
magnet fixed to the impeller. The impeller assembly is free to rotate
on a spindle that is supported at both ends. The spindle is held
captive and does not turn. Front and rear thrust washers are utilized
as wear bearings. The washers are held captive and do not revolve.
This prevents wear on the shaft. With the magnetic coupling the
motor drives the impeller. This coupling eliminates the conventional
shaft seal and its possibility of leakage.
PUMP MATERIALS
The pump's plastic parts are made of glass-filled polypropylene.
The spindle shaft and thrust washers are titanium. The impeller-
driven magnet is uncoated Ceramagnet A (barium ferrite) type
ceramic, and the static O-ring seal is Buna-N.
INSTALLATION
This pump is assembled and tested at the factory, and is ready
for immediate use. It may be installed in any position, including
vertically with the pump head down. To ensure proper plumbing
connections, see the SPECIFICATIONS table to determine the
intake and discharge sizes of your pump. Use thread sealer on
all pipe connections and hand-tighten only. Tighten all wing nuts
before operating the pump. The motor nameplate lists all electrical
data. Make sure the pump is connected to proper voltage before
operating. When wiring a pump with no plug, the green (or green/
yellow) wire is ground, and the other two are line (live).
Do not allow the pump to run dry (without liquid). This pump is
not submersible; operate it only in the in-line mode. Do not put
the pump into liquid. Install the pump in a dry area, protected from
splashing. This pump is not self priming; it must be installed so that
the pump head (volute) is flooded when the pump is started. That
is, the inlet of the pump must be below the level of the surface of the
liquid being pumped (Figure 1).
Do not restrict the intake side of the pump. Connections on the intake
side should not be of smaller inside diameter pipe or tubing or hose
than the intake inside diameter of the intake thread designation. If
reduced flow is required, install a valve or other restriction device on
the discharge side. When using a valve, the pump can be throttled
to provide various flow rates and pressures without harming the
motor or the pump parts.
