INSTALLATION
Tighten Fasteners Before Setup
Before using the pump for the rst time,
check and retorque the housing bolts (23).
Also the valve stops of the discharge valves
(09) have to be checked. Also after the rst
day of operation, after periods of important
temperature
uctuations, after transport, after
dismantling of the pump and after periods
when the pump hasn’t been working the
stops, plugs and housing bolts have to be
checked. For the housing bolts please use
the torque values as mentioned on page 22.

Mounting
The pump exhaust air may contain
contaminants. Ventilate to a remote area.
See Air Exhaust Ventilation on page 9.
Never move or lift a pump under
pressure. If dropped, the uid section may
rupture. Always follow the Pressure Relief
Procedure on page 10 before moving or
lifting the pump.
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 ease of operation and service, mount
the pump so air inlet, uid inlet and uid
outlet ports are easy accessible.
Grounding
The equipment must be grounded.
Grounding reduces the risk of static and
electric shock by providing an escape wire
for the electrical current due to static build
up or in event of a short circuit. In the site
housing a grounding connection is included.
Check your system electrical continuity
after the initial installation. Set up a regular
schedule for checking continuity to be sure
proper grounding is maintained.
Follow your local re codes. When pumping
ammable uids, always ground the entire
uid system as described.
Air Line
See recommended installation drawing
on page 7.
1. Install an air regulator and gauge. Set
pressure of the driving air should be
limited to the pressure required to run
the pump on the desired working point.
Setting the pressure too high will cause
higher wear of the pump and will increase
the compressed air consumption. The
uid stall pressure will be the same as the
setting of the air regulator.
2. If the air regulator do not have a bleed off
function to relieve trapped air, or the air
regulator is not placed close to the pump,
locate a bleed-type master air-valve close
to the pump. Be sure the valve is easily
accessible from the pump.
MPa/bar/PSI
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
3. The master air valve will be used to
regulate the ow rate of the air to the
pump. By using a throttle valve, it is
possible to regulate the pump speed even
at the lower end of the curves.
4. Install a grounded, exible air hose
between the accessories and the pump
air inlet. The inner diameter of the hose
have to be the same diameter of the air
connection of the pump or bigger.

VA-C_man rev01-2016_VI_(uk) | 1.02.2017 9
Air Exhaust Ventilation
Do not restrict the air exhaust port.
Excessive exhaust restriction can cause
erratic pump operation. At a diaphragm
rupture, it is possible the pumped liquid will
escape through the mufer. To prevent this
the air exhaust need to be remote to a safe
environment.
Fluid suction line
1. A shut of valve should be installed just
before the pump to isolate the pump
from the system for maintenance and
installation.
2. Always use a exible connection to avoid
vibrations being brought into the piping
system.
3. Use a suction line which can stand
vacuum. By the pumping action, vacuum
will be created at the suction side of the
pump.
4. The inner diameter of the hose should be
equal to the connection diameter of the
pump.
5. If the 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 inefcient pump
operation and is a possible cause of noise.
6. Inlet pressure greater than 1 bar (15
PSI), diaphragm life will be shortened.
Fluid outlet line
1. A shut of valve should be installed just
after the pump to isolate the pump
from the system for maintenance and
installation. A drain valve should be
installed to relief the pressure of the
pump before starting maintenance work
at the pump.
2. Always use a exible connection to avoid
vibrations being brought into the piping
system.
Fluid inlet and outlet ports
VA-C series of pump are having the suction
and discharge connections integrated in the
center block. Suction connection is horizontal
and discharge vertical. Pay attention to this
conguration as this is only valid for correct
pump function.
Installation remarks
1. VA-C pumps must be installed load free
to avoid possible damage of pumps
and/or installation.
2. VA-C pumps will be delivered with blind
plugs to prevent dust or other materials
to enter the pump. Those plugs have to
be removed before installing the pump!
3. As UV – radiation can damage
Polyethyene. This must taken in account
by installing VA-C pumps are made out of
Conductive PE.
4. The air-valves used in VA-C pumps are
manufactured with tight tolerances.
They should be used with clean, dry and
oil-free compressed air. If the quality of
the compressed air at the place where
the pump is installed is not optimal, it is
possible to install a dryer and/or a water
separator. Please contact your distributor
for more detailed information.

Suction

VA-C_man rev01-2016_VI_(uk) | 1.02.2017 10
5. VA-C pumps are dry self-priming. So they
don’t need to be lled before rst use.
The gures of the possible suction heights
can be found in the technical information.
(see page 21).
6. VA-C pumps will building up pressure at
the liquid side up to the pressure set on
the compressed air-inlet of the pump.
If this pressure is higher than the rated
pressure of the discharge line, a pressure
relief valve or another pressure safety
equipment should be installed at the
discharge side of the pump.
7. VA-C pumps can stall against a closed
discharge line without damage. The pump
will stop working when the pressure at
the liquid side of the diaphragms is equal
(or higher) then the compressed air
pressure at the air-side of the diaphragm.
As soon the pressure at the liquid side will
drop below the compressed air pressure,
the pump will restart automatically.
Due to internal losses, occasionally the pump
can make a stroke during stalling.
OPERATION
Pressure relief procedure
MPa/bar/PSI
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the uid drain valve to relieve uid
pressure. Have a container ready to catch
the drainage.
Flushpumpbeforerstuse
The pump was tested before leaving the
factory. Residue of the testing water can be
left in the pump. To avoid contamination,
ush the pump before rst use.
Starting and adjusting the pump
1. Be sure the pump is properly grounded.
See page 8 for proper grounding.
2. Check ttings to be sure they are tight.
Tighten uid inlet and outlet ttings
securely.
3. Place the suction tube (if used) in uid
to be pumped.
NOTE: If uid inlet pressure to the pump is
more than 25% of outlet working pressure,
the ball check valves will not close fast
enough, resulting in inefcient pump
operation.
4. Place the end of the uid hose into an
appropriate container.
5. Close the uid drain valve.
6. Back out the air regulator knob, and open
all bleed-type master air valves.
8. Slowly increase air pressure with the air
regulator 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. Trapped air can cause the
pump to cycle unexpectedly, which could
result in serious injury from splashing.
9. If you are ushing, run the pump long
enough to thoroughly clean the pump
and hoses.
10. Close the bleed-type master air valve.
Pump shutdown
MPa/bar/PSI
At the end of the work shift and before you
check, adjust, clean or repair the system,
follow Pressure Relief Procedure, in the
left column here.

VA-C_man rev01-2016_VI_(uk) | 1.02.2017 11
Special precautions
1. When medium is left in the pump
chambers, this can generate chemical
reactions when pumping another uid.
Always ush pumps with a neutral uid
before changing from medium.
2. Take care liquids left in the pump chamber
can’t freeze, this can damage the pump.
3. It is possible to run the pumps on
nitrogen gas instead of compressed air.
Take care about sufcient ventilation
around the pump as the exhaust of
the pump will put nitrogen gas in the
atmosphere.
4. Using the pump submerged: It is
necessary to connect the air outlet of
the pump to the atmosphere be using
a exible hose, to prevent liquid to
enter the air side of the pump. Take in
consideration , all external parts of the
pump must be 100% resistance to the
medium where the pump is placed in.
Special care have to been taken the pump
is standing 100% vertical and can’t start
to oat in all circumstances.
5. In case of big changes in temperature
while operating, it is necessary to control
the tension on the bolts carefully. Sudden
big temperature shocks can cause over or
under tightening of the pump and will lead
to leaks and/or damage the pump.
MAINTENANCE / REPAIR
Flushing and storage
Flush the pump often enough to prevent
the uid you are pumping from drying
or freezing in the pump and damaging
it. Always ush the pump and follow the
Pressure relief Procedure on page 10
before storing it for any length of time.
Use a compatible ushing agent.
Tightening Threaded connections
Before each use, check all hoses for wear
or damage and replace as necessary. Check
to be sure all threaded connections are tight
and leak-free. Tighten and retorque the
pump if necessary. Use torque values on
page 22
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.
Disassembly
IMPORTANT:
Follow the Pressure Relief Procedure
at page 10 before starting to work at the
pump !
After a diaphragm rupture always make
sure no liquid is left at the air side of the
pump. Especially the mufer (07) have
to be checked before opening the pump.
The uid side of the range of VA-C pumps
are built together the same way. The only
difference are the number of assembly (23)
pins used. VA-C pumps are having different
right and left side housings (02 and 03).
1. The center section has the same built up
for VA-C50 and VA-C130. The air valves
for the VA-C10 and the VA-C20 are not
having an air valve shaft. On those pumps
the diaphragm shaft (19) is also used as
piston shaft. Due to this the VA-C10 and
VA-C20 are not having diaphragm shaft
o-rings and diaphragm shaft bearings (20)
mounted in the center housing.
Every Verderair CONT-EX pump is delivered
with a tool to disassemble the air valve.
