Installation
General Information
The Typical Installation shown in Fig. 2 is only a guide for
selecting and installing system components. Contact your
VERDER Customer Service for assistance in planning a sys-
tem to suit your needs.
Always use Genuine VERDER Parts and Accessories.
Reference numbers and letters in parentheses refer to the
callouts in the figures and the parts lists on pages 25–29.
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 manuals. Read the fluid and
solvent manufacturer’s warnings.
Warning
Grounding
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before operat-
ing the pump, ground the system as ex-
plained at right. Also read the section FIRE
AND EXPLOSION HAZARD on page 3.
The acetal and conductive polypropylene pumps con-
tain a conductive additive that makes the wetted parts
conductive. Attaching the ground wire to the grounding
screw grounds the air motor and the wetted parts. The
non–conductive polypropylene and PVDF pumps are
not conductive. Attaching the ground wire to the
grounding screw grounds only the air motor.
When pumping conductive flammable fluids, always
ground the fluid system by making sure the fluid has an
electrical path to a true earth ground. See Fig. 1.
Never use a non–conductive polypropylene or PVDF
pump 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-centime-
ters.
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equip-
ment.
Warning
Ground all of this equipment:
D
Pump: Connect a ground wire and clamp as shown in
Fig. 1. Loosen the grounding screw (W). Insert one end of
a 1.5 mm
2
minimum ground wire (Y) behind the ground-
ing screw and tighten the screw securely. Connect the
clamp end of the ground wire to a true earth ground. Or-
der Part No. 819.0157 Ground Wire and Clamp.
NOTE: When pumping conductive flammable fluids with a
non–conductive polypropylene or PVDF pump, always
ground the entire fluid system. See the WARNING on left.
Fig. 2. shows a recommended method of grounding flam-
mable fluid containers during filling.

D
Air and fluid hoses: Use only grounded hoses with a
maximum of 150 m combined hose length to ensure
grounding continuity.
D
Air compressor: Follow manufacturer’s recommenda-
tions.
D
All solvent pails used when flushing, according to local
code. Use only grounded metal pails, which are conduc-
tive. Do not place the pail on a non-conductive surface,
such as paper or cardboard, which interrupts the ground-
ing continuity.
D
Fluid supply container: Follow your local code.
Tightening Screws Before First Use
Before using the pump for the first time, check and retorque
all external fasteners. See Torque Sequence, page 30.
After the first day of operation, retorque the fasteners.
Although pump use varies, a general guideline is to retorque
fasteners every two months.
