Installation - Graco Husky 515 D51 Series Instructions Manual

General Information
•
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.
•
Always use Genuine Graco Parts and Accessories.
•
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 Sequence,
page 29. After the first day of operation, retorque the
fasteners. Although pump use varies, a general guide-
line 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 cer-
tain chemicals. Consult engineering guides for chemi-
cal compatibilities and temperature limits, or contact
your Graco distributor.

Installation

Mountings
•
These pumps can be used in a variety of
installations. Be sure the mounting surface can
support the weight of the pump, hoses, and
accessories, as well as the stress caused during
operation.
•
Fig. 2 shows some installation examples. On all
installations, mount the pump using screws and
nuts.
•
Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do
not expose pump or the plastic components to direct
sunlight for prolonged periods.
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.
