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
Read Toxic Fluid Hazard on
page 3.
Use fluids and solvents that are compatible with the equip-
ment 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 certain chemi-
cals. 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.
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 perfor-
mance significantly. Stainless steel balls should be used for
such applications.

819.6900 5
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 un-
expectedly, 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 con-
ductive.
a. The fluid pressure can be controlled in either of two
ways. To control it on the air side, install an air regu-
lator (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. Connect the other end of the tubes to the external air
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 hazard-
ous 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 con-
trol 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.

6 819.6900
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 ex-
haust port. Excessive exhaust restriction can cause erratic
pump operation.
See Venting Exhaust Air in Fig. 2. Exhaust to a remote
location as follows:
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.
The 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 con-
ductivity greater than 50 x 10–12 Siemans/meter (ohms/me-
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 1012 ohm-centimeters.
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.
NOTE: When pumping conductive flammable fluids with a
non–conductive polypropylene or PVDF pump, al-
ways ground the fluid system. See the warning
above. Fig. 3 shows a recommended method of
grounding flammable fluid containers during filling.
Ground all of this equipment:
Pump: The metal pump has a grounding strip in front of
the center housing. The acetal and conductive polypropy-
lene 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 conti-
nuity.
Fluid supply container: Follow the local code.

Operation
Pressure Relief Procedure
Warning
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious injury
from pressurized fluid, accidental spray, or splashing fluid,
follow this procedure whenever you:
Are instructed to relieve pressure;
Stop pumping;
Check, clean or service any system equipment;
Install or clean fluid nozzles.
1. Shut off the air to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve all fluid pressure,
and have a container ready to catch the drainage.
Flush the Pump Before First Use
The pump was tested with water. Prior to first use, flush the
pump thoroughly with a compatible solvent. Follow the steps
under Starting and Adjusting the Pump.
Starting and Adjusting the Pump
1. Read Toxic Fluid Hazard on
page 3.
2. If lifting the pump, follow the Pressure
Relief Procedure above.
3.
Be sure the pump is
properly grounded.
Read Fire and Explo-
sion Hazard on
page 3.
4. Check all fittings to be sure they are tight. Use a compat-
ible liquid thread sealant on all male threads. Tighten the
fluid inlet and outlet fittings snugly. Do not over–tighten
the fittings into the pump.
5. Place the suction tube (if used) in the fluid to be pumped.
NOTE: If the inlet fluid pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in ineffi-
cient pump operation.
6. Place the end of the fluid hose (K) into an appropriate
container.
7. Close the fluid drain valve (H).
8. With the pump air regulator (G) closed, open all bleed-
type master air valves (B, E).
9. If the fluid hose has a dispensing device, hold it open
while continuing with the following step. Slowly open the
air regulator (G) until the pump starts to cycle. Allow the
pump to cycle slowly until all air is pushed out of the lines
and the pump is primed.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air
regulator. Remove the suction tube from the solvent
and place it in the fluid to be pumped.
Operation of Remote Piloted Pumps
1. Follow steps 1–8 above.
2. Open the air regulator (G).
Warning
The pump may cycle once before the external signal is
applied.
3. The pump will operate when air pressure is alternately
applied to the push type connectors (16).
NOTE: Leaving air pressure applied to the air motor for ex-
tended periods when the pump is not running may
shorten the diaphragm life. Using a 3–way solenoid
valve to automatically relieve the pressure on the air
motor when the metering cycle is complete prevents
this from occurring.
Pump Shutdown
At the end of the work shift, relieve the
pressure as described in Pressure Re-
lief Procedure at left.

819.6900 11
Maintenance
Lubrication
The air valve is lubricated at the factory to operate without
additional lubrication. If you want to provide additional lubri-
cation, remove the hose from the pump air inlet and add two
drops of machine oil to the air inlet every 500 hours of opera-
tion or every month.
Caution
Do not over-lubricate the pump. Oil is exhausted through the
muffler, which could contaminate your fluid supply or other
equipment. Excessive lubrication can also cause the pump to
malfunction.
Flushing and Storage
Flush the pump to prevent the fluid you are pumping from
drying or freezing in the pump and damaging it. Use a com-
patible solvent.
Always flush the pump and relieve the pressure before you
store it for any length of time.
Read Pressure Relief Procedure on
page 10.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage and
replace as necessary. Check to be sure all threaded connec-
tions are tight and leak-free.
Check fasteners. Tighten or retorque as necessary. Al-
though pump use varies, a general guideline is to retorque
fasteners every two months. See Torque Sequence, page
30.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based on
the pump’s service history. This is especially important for
prevention of spills or leakage due to diaphragm failure.

12 819.6900
Troubleshooting
Read Pressure Relief Procedure on page 10, and relieve the pressure before you check or service the equip-
ment. Check all possible problems and causes before disassembling the pump.

o-ring (1) into the end of the diaphragm shaft bore of
the center housing (11).
NOTE: Make sure the lips of the u-cup face out of the
center housing.
2. Line up the holes in the gasket (12) with the holes in the
end of the center housing (11), and use six screws (141)
to fasten an air cover (136) to the end of the center
housing (11). Torque the screws to 35 to 45 in-lb (4.0 to
5.1 Nm).
3. Position the exhaust cover (13) and o-ring (4) on the
center housing (11).
