to the callouts in the Figures and the parts lists on
pages 28 to 31.
Tightening Threaded Fasteners Before
First Use
After unpacking the pump, and before using it for the
first time, check and retorque all external fasteners.
See the Service section for torque specifications.
After the first day of operation, retorque the fasteners
again. Although the recommended frequency for
retorquing fasteners varies with pump usage, a general
guideline is to retorque fasteners every two months.
WARNING
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can
cause serious injury or death if splashed
in the eyes or on the skin, inhaled, or
swallowed.
1. Read TOXIC FLUID HAZARD on page 3.
2. Use fluids and solvents which are compatible
with the equipment wetted parts. Refer to the
Technical Data section of all equipment manu-
als. Read the fluid and solvent manufacturer’s
warnings.
CAUTION
Safe Operating Temperature
Minimum: 40
_
F (4.4
_
C); Maximum: 150
_
F (66
_
C).
These temperatures are based upon mechanical
stress only and may be significantly altered by
pumping certain chemicals. Consult engineering
guides for chemical compatibilities and temperature
limits, or contact your Graco distributor.
Mountings
D
Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
D
The Husky 715 Pump can be used in a variety of
installations. See Figs. 3 to 5 for some examples.
D
When installed on a drum (see Fig. 4), slide the
pump’s feet securely under the rim of the drum.
D
On all other installations, mount the pump using
screws and nuts.
Pumping High Density or Abrasive Fluids
High density fluids prevent the lightweight PTFE and
buna-N check valve balls from seating properly, which
reduces pump performance significantly. Use stainless
steel balls for such applications (see page 31). Refer
to page 21 to change the balls.
Dual Manifolds
Dual manifold kits are available to enable you to pump
two fluids simultaneously, or to mix two fluids in the
pump. Order Part No. 237–633 for acetal pumps and
Part No. 237–632 for polypropylene pumps.
