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
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.
•Always ground the entire fluid system as
described below.
• Polypropylene pumps are not conductive and are
not for use with flammable fluids.
• Follow your local codes and regulations.
•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.

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.

Installation
8 812.0062
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.
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 Technical Specifications, page 15,
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
grounded.
a. Install an air regulator (C) and air pressure
gauge (V) 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. 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 a conductive, grounded, flexible air supply
line (A) between the accessories and the 3/4 npt(f)
pump air inlet (M).
The pump is very heavy (see Technical
Specifications on page 15 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 (B) 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
812.0062 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 L).
2. Install a fluid drain valve (J) close to the pump fluid
outlet. See FIG. 2.
3. Install a fluid shutoff valve (K) in the fluid outlet line
(L) downstream from the fluid drain valve (J).
NOTE: For best results, always install the pump as
close as possible to the material source. See the
Technical Specifications, page 15, 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 (J) 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.
