Grounding
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
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
operating the pump, ground the system as
explained below. Also, read the section
FIRE AND EXPLOSION HAZARD on
page 5.
Non-Conductive Polypropylene and PVDF
are not conductive.
Attaching the ground wire to the grounding lug will
ground only the air motor. When pumping conductive
flammable fluids, always make sure the fluid has an
electrical path to a true earth ground. Possible
methods of grounding the fluid are through the fluid
containers or piping. Contact your VERDER
Customer Service for assistance in grounding your
system. Never use a non-conductive polypropylene
or a PVDF pump in an explosive atmosphere with
non-conductive flammable fluids as specified by your
local fire protection code. US Code (NFPA 77 Static
Electricity) recommends a conductivity greater than
50 x 10-12 Siemans/meter (ohms/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 1012 ohm-centimeters.

819.4486 7
Installation
Grounding (continued)
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
equipment. Ground all of this equipment.
•Pump: Connect a ground wire and clamp as shown
in FIG. 1 Loosen the grounding screw (W). Insert
one end of a 1.5 mm² minimum ground wire (Y)
behind the grounding screw and tighten the screw
securely. Connect the clamp end of the ground wire
to a true earth ground. Order Part No. 819.0157
Ground Wire and Clamp.
NOTE: When pumping conductive flammable fluids
with a non-conductive polypropylene or a PVDF
pump, always ground the entire fluid system.
See the Warning on page 6.
•Air and Fluid hoses: Use only electrically conductive
hoses.
•Air compressor: Follow the manufacturer's
recommendations.
•All solvent pails used when flushing, according to
local code. Use only metal pails, which are
conductive. Do not place the pail on a
non-conductive surface, such as paper or
cardboard, which interrupts the grounding
continuity.
•Fluid supply container: Follow the local code.

Installation
Air Line
1. Install the air line accessories as shown in FIG. 2
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the
accessories is electrically conductive.
a. Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be the same as the setting of the air regulator.
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. See the Warning at left. Locate the other
master air valve (E) upstream from all air line
accessories and use it to isolate them during
cleaning and repair.
c. The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2. Install an electrically conductive, flexible air hose (A)
between the accessories and the 1/2 npt(f) pump air
inlet (N). See FIG. 2. Use a minimum 13 mm ID air
hose.
3. Screw an air line quick disconnect coupler (D) onto
the end of the air hose (A); be sure the coupler
porting is large enough to not restrict the air flow,
which will affect pump performance. Screw the
mating fitting into the pump air inlet snugly. Do not
connect the coupler (D) to the fitting until you are
ready to operate the pump.
Fig. 2 ______________________________________________________________________________________
Warning
A bleed-type master air valve (B) is required in your
system to relieve air trapped between this valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury,
including splashing in the eyes or on the skin, injury
from moving parts, or contamination from hazardous
fluids. See FIG. 2.

Installation
Mountings
1. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
2. For all mountings, be sure the pump is bolted
directly to the mounting surface.
3. For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet and
outlet ports are easily accessible.
4. Rubber Foot Mounting Kit 819.4333 is available to
reduce noise and pump movement during
operation.
5. 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.
Fluid Suction Line
1. The pump fluid inlet (R) is a 1-1/2 in. raised face
flange. Refer to Flange Connections on page 10.
2. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in
inefficient pump operation.
3. At inlet fluid pressures greater than 1.05 bar,
diaphragm life will be shortened.
4. See the Technical Data on page 33 for maximum
suction lift (wet and dry).
Fluid Outlet Line
1. The pump fluid outlet (S) is a 1-1/2 in. raised face
flange. Refer to Flange Connections on page 10.
2. Install a fluid drain valve (J) near the fluid outlet. See
the Warning above.
Caution
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See Air Exhaust Ventilation
on page 12.
Warning
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the
risk of serious injury, including splashing in the eyes
or on the skin, or contamination from hazardous fluids
when relieving pressure. Install the valve close to the
pump fluid outlet. See FIG. 2.
