Note! Probe head must not exceed 82.2°C 180°F.
Consult factory for high temperature applications.
CAUTION: Verify the chemical compatibility of the
process and cleaning fluid to the pump’s component
materials in the Chemical Resistance Guide (see
Wilden publication E-4).
CAUTION: When choosing pump materials, be sure to
check the temperature limits for all components.
CAUTION: Maximum temperature limits are based
upon mechanical stress only. Certain chemicals
will significantly reduce maximum safe operating
temperatures. Consult engineering guide for chemical
compatibility and temperature limits.
WARNING: Prevention of static sparking – If static
sparking occurs, fire or explosion could result. Pump,
piping, and containers must be properly grounded
whenever discharge of static electricity is a hazard.
DO NOT OPERATE PUMP WITHOUT PROPER
GROUND! It is very important that the control panel
is properly grounded for safe and proper operation.
Do not reverse the hot and neutral wire under any
circumstance. Unit may cause severe electric shock if
used or installed improperly.
CAUTION: Disconnect all power sources prior to
opening control panel. Never operate pump without
control panel lid securely closed.
CAUTION: Vibration and shock to the control panel
should be avoided.
CAUTION: Unit is designed to be powered by 110 VAC
or 220 VAC only. The control panel incorporates an
automated transformer that can handle the following
power supply options: 110V AC - 50Hz, 110V AC - 60
Hz, 220V AC - 50 Hz, 220V AC - 60 Hz.
CAUTION: The Saniflo™ VC pump is not submersible.
Mount control panel where it is not directly in the wash
down area.
CAUTION: Always wear safety glasses when operat-
ing pump. If rupture of wetted components occurs,
material being pumped may be forced from pump and
may create a hazardous situation.
CAUTION: Before any maintenance or repair is
attempted, the compressed air line to the pump should
be disconnected and all air pressure allowed to bleed
from pump. Disconnect all intake, discharge and air
lines. Power down the control panel and disconnect it
from electrical source. Drain the pump by disconnecting
the hopper, sanitary tubing, fittings and check valves
allowing any fluid to flow into a suitable container.
CAUTION: Do not exceed 8.6 Bar (125 psig) air supply
pressure. Minimum air supply pressure required for
operation is 1.7 bar (25 psig).
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to the regulator mounted to the con-
trol panel.
CAUTION: Only install pump as per the installation
diagram (see section 5).
CAUTION: Ensure that hopper is not higher than top
of vertical column. When pump is unpowered liquid will
seek its own level and cause damage to controls.
CAUTION:
When connecting the pump to any type of
hopper, never place flex hose into the hopper from the
topside. The hopper should always be connected to the
pump from the bottom using sanitary tubing and fittings .
CAUTION: Tighten all clamp bands at regular intervals
to ensure product containment. Fittings may loosen
due to vibration.
CAUTION: In certain applications the Saniflo™ VC
pump may have to be primed to start the pump.
Applications that may require priming include breast,
thigh meat, tenders and other extremely thick prod-
ucts. The pump can be primed by placing a plastic bag
over the discharge port of the pump.

The Saniflo™ VC pump is an air operated, positive displacement, electrically controlled pump. These drawings show the flow
pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.
FIGURE 1 Once the control panel is
turned on, the compressed air sup-
plied to the panel is directed to the
vacuum generator(s) located within the
control panel. The vacuum generated
by the vacuum generator(s) is applied
to the vertical column of the Saniflo™
VC pump. This vacuum removes atmo-
spheric pressure from the vertical col-
umn drawing the process medium into
the pump past the inlet flap valve and
into the vertical column. The process
medium will continue to rise within the
vertical column of the pump until the
process medium reaches the conductiv-
ity sensor in the pump cap assembly.
FIGURE 2 Once the process medium
reaches the conductivity sensor at the
top of the vertical column, the control
panel senses the process medium and
changes the direction of the air flow.
Now the compressed air supplied to
the controller is switched away from the
internal vacuum generator(s) and directed
into the vertical column of the pump.
Once the compressed air is supplied
to the top of the process medium, the
hydraulic force will discharge the pro-
cess medium from the vertical column.
These same forces will close the inlet
flap valve and open the discharge flap
valve simultaneously causing the pro-
cess medium to move downstream.
FIGURE 3 The discharge stroke length
is controlled by the timer dial located on
the right side of the Saniflo™ VC con-
trol panel. By adjusting the timer dial,
the length of the time the compressed
air is supplied directly to the process
medium within the vertical column can be
adjusted. Once the time has been set,
the compressed air will be directed onto
the process medium for the set time and
then the control panel will redirect the
air to the vacuum generator(s). Once air
is redirected to the vacuum generator(s)
the process medium is once again drawn
up the vertical column towards the con-
ductivity sensor. This constitutes one
complete pumping cycle.

WILDEN PUMP & ENGINEERING CO., LLC WIL-12120-E-01

Section 5
SUGGESTED INSTALLATION
The pipe size should be at least the size of the inlet and
discharge ports of the pump or larger if highly viscous
material is being pumped.The suction hose must be non-
collapsible, reinforced type as the SANIFLO™ VC pump is
capable of pulling a vacuum. It is critical that all fittings
and connections are airtight or a reduction or loss of
pump suction capability will result.
INSTALLATION: Months of careful planning, study
and selection efforts can result in unsatisfactory pump
performance if installation details are left to chance.
Premature failure and long term dissatisfaction can be
avoided if reasonable care is exercised throughout the
installation process.
LOCATION: Noise, safety and other logistical factors
usually dictate where equipment should be situated on
the production floor. Multiple installations with conflicting
requirements can result in congestion of utility areas,
leaving few choices for additional pumps.
Within the framework of these and other existing
conditions, every pump should be located in such a way
that six key factors are balanced against each other to
maximum advantage.
ACCESS: First, the location should be accessible. If it
is easy to reach the pump, maintenance personnel will
have an easier time carrying out routine inspections and
adjustments. Should major repairs become necessary,
ease of access can play a key role in speeding the repair
process and reducing total downtime. Verify that the site
also allows for ease of cleaning and proper drainage
during wash down.
AIR SUPPLY: The HPVC pump is furnished with a one-
half inch (NPT) ball valve as the point of connection for
compressed air. Although air consumption varies with
each application/installation of the HPVC pump; the air
supply should be sized to provide at least 32 CFM @ 75
PSI. Furnished with your pump are an air filter and two
regulatorfilter combinations equipped with automatic
drains. The regulator marked “suction” controls the
amount of pressure available to the vacuum generator.
This pressure should be set at no more than 75 PSI to
ensure maximum efficiency.
The regulator marked “discharge” controls the amount of
pressure used to discharge the product from the pump.
The proper amount of discharge pressure is determined
by several factors including pumping distance, required
flow rate, product viscosity and piping size.
ELECTRICAL : The control panel requires 120/220VAC at
.1 amps.
ELEVATION: Selecting a site that is well within the pump’s
dynamic lift capability will assure that loss-of-prime
troubles will be eliminated. In addition, pump efficiency
can be adversely effected if proper attention is not given
to site location.
PIPING: Final determination of pump site should not be
made until the piping problems of each possible location
have been evaluated. The impact of current installations
should be considered ahead of time to make sure that
inadvertent restrictions are not created for any remaining
sites.
The best choice possible will be a site involving the
shortest and straightest hook-up of suction and discharge
piping. Unnecessary elbows, bends and fittings should
be avoided. Pipe sizes should be selected to keep friction
losses within practical limits. All piping should be
supported independently of the pump. In addition, the
piping should be aligned to avoid placing stresses on the
pump fittings.
If the pump is to be bolted down to a solid location, a
mounting pad placed between the pump stand and the
foundation will assist in minimizing pump vibration.
The proper orientation for this SANIFLO™ VC pump is to
have the vertical column in the vertical position.
SOLIDS PASSAGE CAPABILITIES:
CONNECTING PUMP TO CONTROL PANEL: The control
panel should be connected to the pump as close as
possible without putting the control panel in harms way.
The control panel comes complete with seven feet of hose
to connect the control panel to the pump.The control panel
may be mounted farther from the pump than seven feet,
but this will decrease the capacity of the pump slightly.
Moving the control panel farther away will also increase
the air consumption by approximately five-percent for
every additional ten feet of air tubing. The sanitary cap
which houses the probe and diffuser screen is placed on
top of the vertical tube and secured by a four inch sanitary
clamp.Your pump is now connected to the control panel.
CONNECTING PUMP TO HOPPER: The correct way to
connect the hopper to the pump is from the bottom of
the hopper using sanitary pipe & fittings. NOTE: When
connecting pump to any type of hopper, never place the
flex hose into the hopper from the topside. The hopper
should always be connected to the pump from the bottom
of the hopper.

The PLC is the center of the HPVC control panel. The PLC
interprets the signal from the probe, sets the timing of the
pumping sequence, monitors for common problems, and
provides diagnostic feedback to an operator the ensure
maximum reliability and up-time. Very little physical
interaction with the PLC is required as most common
adjustments to the pump are made from the exterior of the
control panel. During normal operation; the PLC display
will display the discharge timer value, probe value, and
pump status.
The discharge timer value is the amount of time (in
seconds) that the pump will spend in discharge mode
after receiving the signal from the probe. The discharge
timer value can be easily adjusted with the potentiometer
located on the right side of the control panel. The
discharge timer has a maximum value of 10 seconds and
a minimum value of 1/10th of a second.
The probe value is a measure of continuity of the product
being pumped, measured between the tip of the probe
and the reservoir tube. The range has a maximum value
of 1024 and a minimum value of 0. Typically, a very low
number indicates that the probe is not in contact with
the product being pumped (reservoir tube is empty).
Typically, a high number would indicate that product is in
contact with the probe (reservoir tube is full). In the above
figure a value of 2 is being displayed meaning that the
pump is empty of product.
The pump status alerts the operator to the current status of
the pump. The status will change from “off” to “suction”
or “discharge” depending on the position of the run/purge
switch (located on the right side of the control panel) and
the pumps current position in the pumping sequence.The
status will indicate “waiting” when downstream control
of the pump is used and product is no longer needed
from the pump.
THE ADJUSTABLE PROBE
During operation, certain products can coat the sensor
probe creating false inputs to the control panel and
causing poor performance. Periodic cleaning of the sensor
probe may be required in certain applications to maintain
reliability. To decrease the frequency of cleanings, the
HPVC control panel has an adjustable probe set point. This
set point can be changed on the fly to offset the effects of
product build-up on the sensor probe during operation.
To adjust the probe set point, follow these steps:
Write down the probe value (displayed on the PLC)1.
when the reservoir tube of the pump is empty. Use the
manual discharge switch to ensure the pump is empty.
This value should be close to zero. A reading higher than
0 (ex. 100) indicates that the probe has some fouling
and that the set point can be adjusted to compensate.
An extremely high reading while the pump is empty
(ex. 500) indicates that the probe is heavily fouled and
should be cleaned before proceeding. After recording
this value proceed to step 2.
Write down the probe value when the reservoir tube2.
of the pump is full and the probe is in contact with the
product. To accomplish this, watch the PCL display, use
the run switch to jog the pump until the probe value
jumps significantly (ex. 600). This indicates the probe
has made contact with the product being pumped.
Record this number and proceed to step 3.
Using the two numbers you’ve written down, subtract3.
the low value from the high value and divide the
remainder by two. The quotient is our new probe set
point. Record this number and proceed to step 4.
From the PLC display, press the info button and release.4.
A new screen will be displayed requiring a password
to proceed. Enter the password “3433” then press the
enter button and release.

The next screen contains the probe set point value.5.
Using the numeric keys, enter the new value you
calculated in step 3 and press the enter button and
release. You have now changed the probe set point.
**note** The pumping cycle is toggled only after
the probe value has risen above the set point value;
therefore, the set point value must always lie between
the maximum and minimum readings from steps 1
and 2. If a set point value is calculated that is greater
than the maximum or less than the minimum values
from steps 1 and 2, repeat all steps.
THE DELAY TIMERS:
After changing the probe set point the following screen
will automatically be displayed.
This screen allows the operator to change the suction and
discharge delay timer values. These delay timers will put
slight pauses in the pumping sequence which can result
in a better pumping action. If there is no specific reason
to utilize these timers, it is suggested that they be left at a
value of zero. In order to change these values simply use
the enter key and the numeric keys to enter the required
values. Timers are in increments of seconds. If you do
not need to change these values and wish to return to the
main screen, Press the enter key three times.
THE ALARMS:
An alarm screen will be displayed if conditions exist that
would stop normal operation of the pump.The pump will
remain stopped and the alarm will be displayed until the
condition is corrected and the pump control is reset. This
screen alerts the operator to the nature of the problem
and provides instructions to solve the problem and restart
the pump.
This screen indicates that product has been in contact
with the probe for a period of time that was unexpectedly
long. To identify the cause, the operator should make
sure that:
Air shut-off valve is in the open position6.
Discharge pressure is set high enough to move product7.
(try 2.8 bar (40 PSI)
Probe is clean8.
Air supply is adequate9.
No blockage exist in the discharge piping10.
After correcting the condition, to restart the pump simply
cycle the run switch to the off position and return it to the
run position. If the alarm condition has been corrected,
the pump will return to normal operation. If the alarm
screen is displayed again contact maintenance personnel
for a thorough evaluation including calculation of the
probe set point value.
BASIC ADJUSTMENTS:
The HPVC pump has four basic adjustments that are as
follows:
Discharge timer (adjustment on side of panel)11.
Vacuum pressure (regulator marked suction)12.
Discharge pressure (regulator marked discharge)13.
Sensor probe set point (set via the PLC)14.
A good starting point for most applications is to set the
pressure at the suction regulator to 5 bar (75 PSI) and the
pressure at the discharge regulator to 2.8 bar (40 PSI). The
timer should be set at two seconds. The probe set point
should be set to 500. Adjust as necessary.

Section 5
TROUBLESHOOTING
Thick products or high pumping volumes may require
you to increase the discharge pressure. The discharge
pressure will control the velocity of the product coming
out of the pump and should be adjusted according to the
desired product flow. The time value on the controller
is the interval that the pump is in the discharge mode.
A pump set to a short time interval will discharge small
amounts of product and cycle too quickly. A pump set
to a long time interval will force too much product out of
the tube and air lock the check valves. Please note that on
very fragile products like tenders or fillets, a longer stroke
is more advantageous because the check valves will come
in contact with fewer pieces of product.
• Please note that in certain applications the HPVC pump
may have to be primed to start the pump. Applications
that may require priming include breast, thigh meat,
tenders and other extremely thick products. The pump
can be primed by placing either your hand or other
object (i.e. plastic bag) over the exit end of the pipe
connected to the pump. Once the pump cycles twice
nothing else will be required.
