Installation
General Information
D The Typical Installations in Fig. 2 are only guides
for selecting and installing system components.
Contact your Graco distributor for assistance in
planning a system to suit your needs.
D Always use Genuine Graco Parts and Accessories.
D Use a compatible, liquid thread sealant on all male
threads. Tighten all connections firmly to avoid air
or fluid leaks.
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 29. After the first day of operation,
retorque the fasteners. Although pump use varies, a
general guideline is to retorque fasteners every two
months.
Toxic Fluid Hazard
Read Toxic Fluid Hazard
on page 3.
Use fluids and solvents that 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.
CAUTION
Safe Operating Temperatures
Minimum (all pumps): 40_ F (4_ C)
Maximum
Acetal: 180_ F (82_ C)
Polypropylene: 150_ F (66_ C)
Aluminum, stainless steel, PVDF: 225_ F (107_ C)
These temperatures are based upon mechanical stress
only and may be significantly altered by pumping certain
chemicals. Consult engineering guides for chemical com-
patibilities and temperature limits, or contact your Graco
distributor.
Mountings
D These pumps can be used in a variety of installa-
tions. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
D Fig. 2 shows some installation examples. On all
installations, mount the pump using screws and
nuts.
Pumping High-Density Fluids
High density fluids may prevent the lighter non-metallic
check valve balls from seating properly, which reduces
pump performance significantly. Stainless steel balls
should be used for such applications.
Split Manifolds
Plastic Split Manifold Kits are available to enable you
to pump two fluids simultaneously or to mix two fluids
in the pump. To order a Split Manifold Kit, use the Part
No. from the list below:
241240 polypropylene; split inlet
241241 acetal; split inlet
241242 PVDF; split inlet
241243 polypropylene; split outlet
241244 acetal; split outlet
241245 PVDF; split outlet
