Installation
General Information
1.
The Typical Installation shown in F
. 2 is only a guide
for selecting and installing system components. Contact
your VERDER Customer Service for assistance
in planning a system to suit your needs.
2.
Always use Genuine VERDER Parts and Accessories.
Be sure all accessories are adequately sized and
pressure-rated to meet the system’s requirements.
3.
Reference numbers and letters in parentheses refer to
the callouts in the figures and the parts lists on pages
28–29.
4.
Variations in color between the plastic components of
this pump are normal. Color variation does not affect the
performance of the pump.
Tightening Screws Before First Use
Before using the pump for the first time, check and retorque
all external fasteners. See Diaphragm Kits, 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.
Grounding
The non–conductive polypropylene and PVDF pumps are
not conductive. Attaching the ground wire to the grounding
strip grounds only the air motor.
When pumping conductive flammable fluids, always ground
the entire fluid system by making sure the fluid has an
electrical path to a true earth ground. See F
Never use a non–conductive polypropylene or PVDF pump
in an explosive atmosphere or with non-conductive
flammable fluids as specified by your local fire protection
code.
U.S. Code (NFPA 77 Static Electricity) recommends a
conductivity greater than 50 x 10
–12
Siemans/meter
(mhos/meter) over your operating temperature range to
reduce the hazard of fire. Consult your fluid supplier to
determine the conductivity or resistivity of your fluid. The
resistivity must be less than 2 x 10
12
ohm-centimeters.
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 5.
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
