Installation
General Information
D The Typical Installations in Fig. 4 to Fig. 7 are only
guides for selecting and installing system compo-
nents. Contact your Graco distributor for assistance
in planning a system to suit your needs.
D Always use Genuine Graco Parts and Accessories,
available from your Graco distributor. Refer to the
Product Data Sheet for the pump, Form No.
305528 (acetal pumps) or 305543 (polypropylene
pumps). If you supply your own accessories, be
sure they are adequately sized and pressure rated
for your system.
D Use a compatible, liquid thread sealant or PTFE
tape on all male threads. Tighten all connections
firmly to avoid air or fluid leaks. Do not over-
tighten plastic threads.
D Reference numbers and letters in parentheses refer
to the callouts in the Figures and the parts lists on
pages 28 to 29.
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.
WARNING
Safe Operating Temperature
Minimum: 40_F (4.4_C); Maximum: 150_F (66_C).
Operating outside these temperature limits will
adversely affect the strength of the pump housing.
Certain chemicals may further reduce the operat-
ing temperature range. Consult engineering guides
for chemical compatibilities and temperature limits,
or contact your Graco distributor.
CAUTION
Tightening Threaded Fasteners Before
First Use
Before using the pump for the first time, check and
retorque all external fasteners. See Torque Se-
quence, page 32. After the first day of operation,
retorque the fasteners. Although pump use varies, a
general guideline is to retorque fasteners every two
months.
Mountings
D Be sure the mounting can support the weight of the
pump, hoses, and accessories, as well as the
stress caused during operation.
D The Husky 307 Pump can be used in a variety of
installations, some of which are shown in
Fig. 4 to Fig. 7. Kits are available to adapt your
pump to your system. Refer to the Product Data
Sheet for the pump, Form No. 305528 (acetal
pumps) or 305543 (polypropylene pumps).
D For all other mountings, be sure the pump is ade-
quately secured.
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. 237211 for acetal pumps and
Part No. 237210 for polypropylene pumps.
