Installation
General Information
D The Typical Installations in Fig. 5 to Fig. 7 are only
guides for selecting and installing system components.
Contact your Graymills distributor for assistance in
planning a system to suit your needs.
D Always use Genuine Graymills Parts and Accessories,
available from your Graymills distributor. 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 Teflonr 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 lists on pages 27 to 28.
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 HAZARDOUS FLUIDS on page 2.
2. Use fluids and solvents which are compatible with
the equipment wetted parts. Refer to the Technical
Data section of all equipment manuals. 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 operating
temperature range. Consult engineering guides for
chemical compatibilities and temperature limits, or
contact your Graymills distributor.
CAUTION
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 fasten-
ers 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 pump can be used in a variety of installations, some
of which are shown in Fig. 5 to Fig. 7.
D For all other mountings, be sure the pump is adequately
secured.
Dual Manifolds
Dual manifold kits are available to enable you to pump two
fluids simultaneously, or to mix two fluids in the pump.
