Installation
General Information
• A typical installation is shown in FIG. 2. It is only a
guide 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.
• Reference numbers and letters in parentheses refer
to the callouts in the figures.
Tighten Clamps Before First Use
After you unpack the pump, and before you use it for the
first time, check all clamps, and tighten as necessary.
Grounding
•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 (12 AWG) or thicker ground
wire (X) behind the grounding screw and tighten the
screw securely. Connect the clamp end of the
ground wire to a true earth ground. To order a
ground wire and clamp, order part number
819.0157.
X
WTI4736A
FIG. 1: Ground Wire Connection
•Air and fluid lines: Use only conductive lines with a
maximum of 150 m (500 ft) combined line length to
ensure grounding continuity. Check electrical
resistance of lines. If total resistance to ground
exceeds 29 megohms, replace line immediately.
•Fluid supply container: Follow the local codes and
regulations.
•Pails for solvents and sanitizing solution used when
flushing: Follow local codes and regulations. Use
only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which
interrupts grounding continuity.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

Installation
8 812.0061
Stand and Mounting
For pumps that are provided with a stand, the pump
must be mounted to the stand before securing the pump
to the mounting surface. Ensure that the pump is
securely mounted to the stand.

Horizontal flapper 812.0002 40.00 cm x 35.56 cm
(15.75 in. x 14.0 in.)
1. Ensure that the mounting surface is level and can
support the weight of the pump, lines, and
accessories, as well as the stress caused during
operation.
2. Mount the pump and stand assembly on a level
surface and secure the assembly to the mounting
surface. See Pump Dimensions, pages 15–25, for
dimensions of the mounting holes for your pump.
NOTE: For ease of operation and service, mount
the pump so the air valve cover, air inlet, and fluid
inlet and outlet ports are easily accessible.
Air Line
1. Install the air line accessories as shown in FIG. 2.
Verify that the air line supplying the accessories is
properly grounded.
a. Install an air regulator (B) and air pressure
gauge (T) to control the air pressure. Reducing
the supplied air pressure will reduce the pump’s
fluid outlet pressure.
b. Locate one bleed-type master air valve (C)
close to the pump and use it to relieve trapped
air. Locate the other master air valve (A)
upstream from all air line accessories and use it
to isolate them during cleaning and repair.
c. The air line filter (R) removes harmful dirt and
moisture from the compressed air supply.
2. Install a conductive, flexible air line (D) between the
accessories and the 1/2 npt(f) pump air inlet (F).
Use a minimum 9.5 mm (3/8 in.) ID air line. If
necessary, install an air line coupler (E) between the
air line (D) and the pump air inlet (F), and tighten
until snug.
The pump may be very heavy (see Technical Data
for specific weights). If the pump must be moved,
follow the Pressure Relief Procedure on page 12
and have two people lift the pump by grasping the
outlet manifold securely, or use appropriate lifting
equipment. Never have one person move or lift the
pump.
A bleed-type master air valve (C) is required in the
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. See
FIG. 2.

Installation
812.0061 9
Fluid Suction and Outlet Lines
For best sealing results, use a standard tri-clamp or DIN
style sanitary gasket of a flexible material such as
EPDM, Buna-N, fluoroelastomer, or silicone.
NOTE: Compliance with 3A sanitary standards requires
DIN connections to use certain gaskets. See CCE
Coordination Bulletin Number 2011-3.
1. Install flexible, conductive fluid lines (G and H).
2. Install a fluid drain valve (K) close to the pump fluid
outlet. See FIG. 2.
3. Install a fluid shutoff valve (J) in the fluid outlet line
(G) downstream from the fluid drain valve (K).
NOTE: For best results, always install the pump as
close as possible to the material source. See the
Technical Data for maximum suction lift (wet and dry).
Tips to Reduce Cavitation
Cavitation in a diaphragm pump is the formation and
collapse of bubbles in the pumped liquid. Frequent or
excessive cavitation can cause serious damage,
including pitting and early wear of fluid chambers, balls,
and seats. It may result in reduced efficiency of the
pump. Cavitation damage and reduced efficiency both
result in increased operating costs.
Cavitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any of
these factors.
1. Reduce vapor pressure: Decrease the temperature
of the pumped liquid.
2. Increase suction pressure:
a. Lower the installed position of the pump relative
to the liquid level in the supply.
b. Reduce the friction length of the suction lines.
Remember that fittings add friction length to the
lines. Reduce the number of fittings to reduce
the friction length.
c. Increase the diameter of the suction lines.
d. Ensure the inlet fluid pressure does not exceed
25% of the outlet working pressure.
3. Reduce liquid velocity: Slow the cyclic rate of the
pump.
Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce cavitation.
Viscous liquids are more difficult to pump and more
prone to cavitation.
Verder recommends taking all of the above factors into
account in system design. To maintain pump efficiency,
supply only enough air to the pump to achieve the
required flow.
Verder distributors can supply site-specific suggestions
to improve pump performance and reduce operating
costs.
A fluid drain valve (K) is required to relieve pressure
in the fluid outlet line if it is plugged. The drain valve
reduces the risk of serious injury, including splashing
in the eyes or on the skin, when relieving pressure.
NOTICE
The pump can be damaged if flexible fluid lines are
not used. If hard-plumbed fluid lines are used in the
system, use a short length of flexible, conductive fluid
line to connect to the pump.

Air Exhaust Ventilation
NOTE: The pump exhaust air may contain
contaminants. Ventilate to a remote area if the exhaust
could contaminate your fluid supply.
NOTE: The air exhaust port is 3/4 npt(f). Do not restrict
the air exhaust port. Excessive exhaust restriction can
reduce pump performance.
To provide a remote exhaust:
1. Remove the muffler (M) from the pump air exhaust
port. See FIG. 3.
2. Install a conductive, grounded air exhaust line (N)
and connect the muffler (M) to the other end of the
line. The minimum size for the air exhaust line is
19 mm (3/4 in.) ID. If a line longer than 4.57 m (15 ft)
is required, use a larger diameter line. Avoid sharp
bends or kinks in the line.
3. Place a conductive, grounded container (P) at the
end of the air exhaust line to catch fluid in case of a
diaphragm rupture. See FIG. 3.
FIG. 3: Venting Exhaust Air
Be sure the system is properly ventilated for your type
of installation. You must vent the pump air exhaust to
a safe place, away from people, animals, food
handling areas, and all sources of ignition when
pumping flammable or hazardous fluids. Diaphragm
rupture can cause the fluid being pumped to exhaust
with the air. Place a grounded container at the end of
the air exhaust line to catch the fluid. See FIG. 3.

Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure when-
ever you see this symbol.
1. Close the master air valve (A) to shut off the air to
the pump.
2. Open outbound fluid valve to relieve fluid pressure
from the pump.
a. For simple transfer applications, open either
the fluid shutoff valve (J) or the fluid drain valve
(K).
b. For circulating applications, ensure that the
fluid shutoff valve (J) is closed and open the
fluid drain valve (K).
Sanitize the Pump Before First
Use
NOTE: The pump was built and tested using a food
grade lubricant.
Properly sanitize the pump before first use. The user
must determine whether to disassemble and clean
individual parts or simply flush the pump with a
sanitizing solution.
To simply flush the pump with a sanitizing solution,
follow the steps under Start and Adjust the Pump,
page 13, and Flushing and Storage, page 14. To
disassemble and clean individual parts, refer to the
appropriate Repair manual.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid, follow the
Pressure Relief Procedure when you stop dispensing
and before cleaning, checking, or servicing the
equipment.

Operation
812.0061 13
Start and Adjust the Pump
1. Confirm that the pump is properly grounded. See
Grounding, page 7.
2. Check and tighten all pump clamps and fluid
connections before operating the equipment.
Replace worn or damaged parts as necessary.
3. Connect a flexible fluid suction line (H) from the fluid
to be pumped to the pump fluid inlet port.
4. Connect the flexible fluid outlet line (G) to the pump
fluid outlet port and route the line to the end
container.
5. Close the fluid drain valve (K).
6. Turn the air regulator (B) knob to the lowest air
pressure setting and open the bleed-type master air
valve (C).
7. If the fluid outlet line (G) has a dispensing device,
hold it open while continuing with the following step.
8. To prime the pump, slowly increase air pressure
with the air regulator (B) until the pump starts to
cycle. Do not exceed the maximum operating air
pressure as listed in the Technical Data, pages 17
and 30. Allow the pump to cycle slowly until all air is
pushed out of the fluid lines and fluid exits the outlet
line (G).
NOTE: 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. Inlet fluid pressure higher than 25% of
the outlet working pressure will also shorten diaphragm
life. Approximately 0.21-0.34 bar (0.02-0.03 MPA,
3-5 psi) fluid inlet pressure should be adequate for most
materials.
Pump Shutdown
At the end of each work shift, perform the Pressure
Relief Procedure, page 12.
Flush the pump if necessary. See Flushing and
Storage, page 14.

Maintenance
14 812.0061
Maintenance
Lubrication
The pump is lubricated at the factory. It is designed to
require no further lubrication for the life of the pump.
There is no need to add an inline lubricator under
normal operating conditions.
The air valve is designed to operate unlubricated. If
lubrication is desired, every 500 hours of operation (or
monthly), remove the line from the pump air inlet and
add two drops of machine oil to the air inlet.
Flushing and Storage
• Flush before fluid can dry or freeze in the
equipment, at the end of the day, before storing,
and before repairing equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a sanitizing solution that is compatible
with the fluid being dispensed and the equipment
wetted parts.
• Flushing schedule will vary based on particular
uses.
• Always cycle the pump during the entire flushing
process.
Always perform the Pressure Relief Procedure, page
12, and flush the pump before storing it for any length of
time.
1. Insert the suction tube into sanitizing solution.
2. Open air regulator (B) to supply low pressure air to
the pump.
3. Run the pump for enough time to thoroughly clean
the pump and lines.
4. Close the air regulator.
5. Remove the suction line from the sanitizing solution
and drain pump.
Routine Cleaning of Product
Contact Section of Pump
NOTE: The pump and the system should be cleaned in
accordance with applicable sanitary standard codes and
local regulations.
1. Flush the system. See Flushing and Storage
above.
2. Follow the Pressure Relief Procedure, page 12.
3. If disassembly of the pump is required for cleaning,
refer to the appropriate repair manual.
4. Using a brush or other C.O.P. methods, wash all
product contact pump parts with a sanitizing
solution at the manufacturer’s recommended
temperature and concentration.
5. Rinse these parts again with water and allow parts
to completely dry.
6. Inspect the parts and re-clean any soiled parts.
7. Immerse all product contact parts in an approved
sanitizer before assembly. Leave the parts in the
sanitizer, taking them out only one-by-one as
needed for assembly.
8. Lubricate the clamps, clamping surfaces, and
gaskets with waterproof sanitary lubricant.
9. Circulate the sanitizing solution through the pump
and the system prior to use. Cycle the pump as the
sanitizing solution is circulated.
Tighten Connections
Before each use, check and tighten all pump clamps
and fluid connections before operating the equipment.
Replace worn or damaged parts as necessary.
NOTICE
Do not over-lubricate the pump. Lubricant is
exhausted through the muffler and could contaminate
your fluid supply or other equipment. Excessive
lubrication can also cause the pump to malfunction.
