Check motor.
It may be equipped
with an automatic resetting thermal
protector and may restart unexpectedly
(see specifications chart). Protector tripping
is an indication of motor overloading as a
result of operating the pump at too high a
pressure (over 100 PSI), too high of viscosity,
too high of specific gravity, excessively high
or low voltage, inadequate wiring, incorrect
motor connections, too small a motor
(sized incorrectly, not enough HP), or a
defective motor or pump.
Do not handle pump with wet hands
or when standing in water. Failure to
follow the General Safety Information
and all warnings could result in fatal
electrical shock!
Assembly
(If pump and motor are
pre-assembled, skip assembly.)
1. Refer to Figures 2 and 3.
2. Remove the hex head machine
screw from the ”V“ band clamp.
3. Slide the ”V“ band clamp away
from the mating face (do not
remove from the pump).
4. Match the pump mating face and
motor mounting hub, while mating
shafts and Oldham coupling (Ref.
No. 24, Figure 7).
NOTE: The small
end of coupling goes into pump.
Rotation: When looking at the motor
shaft end, pr
oper motor pump rotation
is clockwise (CW). Flow is left to right
(See Figure 3). Reverse the flow by
r
otating the pump 180˚. Standard mod-
els are equipped with pr
essur
e r
elief
valves. It is important that the relief
valve be on the dischar
ge side of the
pump.
NOTE: Pump can be rotated 360
°
.
5.
Slip the ”V“ band clamp over the
pump and motor halves (See Figure
2) and tighten the hex head clamp
scr
ew to hold the assembly together.
6.
Retighten the ”V“band clamp scr
ew
as necessary. Use thread sealant if
scr
ew keeps coming loose.
Installation
IMPORTANT: In any installations where
property damage and/or personal
injury can occur when the pump is
not operating due to power outages,
discharge line freezing, or any other
reason, a back-up system(s) and/or
war
ning system(s) should be used.
In order to safely use this product, familiar-
ize yourself with this pump and also with
the liquid (chemical, etc.) that is going to
be pumped through the unit. This pump is
not suitable for many liquids.
1. Locate the pump as close to the
liquid source as possible, making
the suction line as short and direct
as possible.
Ambient
temperature around
motor should not exceed 104˚F (40˚C).
2. Open drip-proof motors are
designed to be used in clean, dry
locations with access to an adequate
supply of cooling air.
3. For outdoor installations, the motor
must be protected by a cover that
does not block air flow to and
around the motor.
4. The motor should be securely
fastened to a rigid surface,
preferably metallic. For rigidity,
use largest bolts that will fit
thr
ough the base holes.
Do not use to
pump flammable or
explosive fluids such as gasoline, fuel oil,
kerosene, etc. Do not use in flammable
and/or explosive atmospheres. When
pumping hazardous or dangerous materials,
use only in room or area designated for
that purpose.
For your protection, always wear proper
clothing, eye protection, etc. in case of any
malfunction. For proper handling techniques
and cautions, contact your chemical supplier,
insurance company and local agencies (fire
dept., etc.). Failure to comply with this
warning could result in personal injury
and/or property damage.
PIPING
SUCTION
1. Avoid excessive lengths or number of
fittings and bends in the suction line.
2. Attach suction line to suction inlet.
3. It is recommended that same size
pipe as pump ports be used or, in
cases requiring lengthy piping, the
next larger size pipe be used.
4. If suction lift is greater than what is
indicated in the performance chart,
attach a foot valve below liquid
level at end of suction line to ensure
positive priming. Also note: If fluid
specific gravity is greater than 1.4 or
viscosity greater than 500 SSU, a
foot valve is also recommended.
5.
If solid contaminates ar
e suspected
in a liquid, place a filter in the
suction line.
