Installation
General Information
The Typical Installations in Fig. 2 are only guides for
selecting and installing system components. Contact your
VERDER distributor for assistance in planning a system
to suit your needs.
Always use Genuine VERDER 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 30. 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
Caution
Safe Operating Temperatures
Minimum (all pumps): 40_ F (4_ C)
Maximum
Acetal: 180F (82 C)
Polypropylene: 150F (66 C)
Aluminum, stainless steel, PVDF: 225F (107 C)
These temperatures are based upon mechanical stress only
and may be significantly altered by pumping certain chemicals. Consult engineering guides for chemical compatibilities
and temperature limits, or contact your VERDER distributor.
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.
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.
Fig. 2 shows some installation examples. On all installa-
tions, 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.

Installation
Air Line
Warning
A bleed-type master air valve (B) is required in your system
to relieve air trapped between this valve and the pump.
See Fig. 2. 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.
Caution
The pump exhaust air may contain contaminants. Ventilate
to a remote area if the contaminants could affect your fluid
supply. Read Air Exhaust Ventilation on page 6.
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. The fluid pressure can be controlled in either of two
ways. To control it on the air side, install an air regulator (G). To control it on the fluid side, install a fluid
regulator (J) near the pump fluid outlet (see Fig. 2).
b. Locate one bleed-type master air valve (B) close
to the pump and use it to relieve trapped air. Read
the Warning above. 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 (C)
between the accessories and the 1/4 npt(f) pump air
inlet. Use a minimum 1/4 in. ID air hose. Screw an air
line quick disconnect coupler (D) onto the end of the air
hose (C), and screw the mating fitting into the pump air
inlet snugly. Do not connect the coupler (D) to the fitting
yet.
Installation of Remote Pilot Airlines
1. Connect the air line to the pump as noted above.
2. Connect 1/4 OD tubing to the push type connectors (16)
on the underside of the pump.
NOTE: By replacing the push type connectors, other sizes
or types of fittings may be used. The new fittings will
require 1/8 in. npt threads.
3.
onnect the other end of the tubes to the external air
C
signal, such as Cycleflo (PN 819.9742) or Cycleflo II
(819.9743) controllers.
NOTE: The air pressure at the connectors must be at least
30% of the air pressure to the air motor for the pump
to operate.
Fluid Suction Line
If using a conductive (acetal or polypropylene) pump, use
conductive hoses. If using a non-conductive pump,
ground the fluid system. Read Grounding on page 8.
The fluid inlet port is 1/2 in. or 3/4 in..
At inlet fluid pressures greater than 15 psi; 0.1 MPa
(1 bar), diaphragm life will be shortened.
Fluid Outlet Line
Warning
A fluid drain valve (H) is required in your system to relieve
pressure in the hose if it is plugged. See Fig. 2. 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.
1. Use electrically conductive fluid hoses (K). The pump
fluid outlet is 1/2 in. or 3/4 in. Screw the fluid fitting into
the pump outlet snugly. Do not over–tighten.
2. Install a fluid regulator (J) at the pump fluid outlet to control fluid pressure, if desired (see Fig. 2). See Air Line,
step 1a., for another method of controlling pressure.
3. Install a fluid drain valve (H) near the fluid outlet. Read
the warning above.
819.6900 5
Installation
Fluid Pressure Relief Valve
Caution
Some systems may require installation of a pressure relief
valve at the pump outlet to prevent over–pressurization and
rupture of the pump or hose. See Fig. 1.
Thermal expansion of fluid in the outlet line can cause over–
pressurization. This can occur when using long fluid lines
exposed to sunlight or ambient heat, or when pumping from a
cool to a warm area (for example, from an underground tank).
Over–pressurization can also occur if the VERDERAIR pump
is being used to feed fluid to a piston pump, and the intake
valve of the piston pump does not close, causing fluid to back
up in the outlet line.

Air Exhaust Ventilation
Read Toxic Fluid Hazard on
page 3.
Read Fire and Explosion
Hazard on page 3.
Be sure the system is properly ventilated for your type of
installation. You must vent the exhaust to a safe place,
away from people, animals, food handling areas, and all
sources of ignition when pumping flammable or hazardous
fluids.
Diaphragm failure will cause the fluid being pumped to
exhaust with the air. Place an appropriate container at the
end of the air exhaust line to catch the fluid. See Fig. 2.
The air exhaust port is 3/8 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic
pump operation.
Fig. 1
See Venting Exhaust Air in Fig. 2. Exhaust to a remote
location as follows:
1
2
9073A
1. Remove the muffler (W) from the pump air exhaust port.
2. Install an electrically conductive air exhaust hose (X)
and connect the muffler to the other end of the hose.
The minimum size for the air exhaust hose is 3/8
in.(10 mm) ID. If a hose longer than 15 ft (4.57 m) is
required, use a larger diameter hose. Avoid sharp bends
or kinks in the hose.
3. Place a container (Z) at the end of the air exhaust line to
catch fluid in case a diaphragm ruptures. See Fig. 2.

Grounding
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 Explo-
sion Hazard on page 3.
The acetal and conductive polypropylene
VERDERAIR VA 15 pumps contain a conduc-
tive additive that makes the wetted parts con-
ductive. Attaching the ground wire to the grounding screw
(106) grounds the wetted parts. See grounding screw on
page 25.
T
he metal M60 pumps have a grounding strip connecting
the vee clamps (109). Attach a ground wire to the grounding
strip with the screw, lockwasher, and nut as shown in the
Grounding Detail on page 28.
The non–conductive polypropylene and PVDF VERDERAIR
VA 15 pumps are not conductive.
When pumping conductive flammable fluids, always ground
the entire fluid system by making sure the fluid system has
an electrical path to a true earth ground (see Fig. 3). Never
use a non–conductive polypropylene or PVDF pump 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
ter) 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
Siemans/meter (ohms/me-
12
ohm-centimeters.
Ground all of this equipment:
Pump: The metal pump has a grounding strip in front of
the center housing. The acetal and conductive polypropylene pumps have a grounding screw on the top manifold.
Connect the non-clamp end of the ground wire to the
grounding strip or grounding screw, and connect the
clamp end of the ground wire to a true earth ground. To
order a ground wire and clamp, order Part No. 819.0157.
Air and fluid hoses: Use only electrically conductive
hoses.
Air compressor: Follow the manufacturer’s recommenda-
tions.
Solvent pails used when flushing: Follow the local code.
Use only grounded 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.
