2. Installation
2.1 Precautions
Handling
Do NOT lift pump by proximity cables,
quick exhaust valves nor air tubing.

Installation Orientation
PXA140B pumps must be installed in an
upright position. The check valves are
actuated by gravity and/or flow, and they
will not seat if the pump is not upright.

Timer Mode
PXA140B pumps require an end of stroke
detection mechanism (pressure switch)
to prevent over stroking in timer mode.
Operating a PXA140B in timer mode without
stroke detection will void the pump warranty.

Required Air Flow (Shuttle Valve)
PXA140B pumps require 3/8 in minimum
orifice with unrestricted air flow.

Required Air Flow (Solenoid Valve)
PXA140B pumps require a 3 Cv solenoid.
Using a reduced Cv will reduce flow rates.
Using a valve with more than 20% greater
Cv will change operating parameters, reduce
pump life and void the warranty.

Under Supply of Air
PXA140B pumps operate erratically or stall
when air supply is insufficient. Ensure use
of air supply pressures higher than averaged
air consumption lines in performance charts.
Air supply lines and fittings must meet
minimal inner diameter requirements
shown in the installation instructions.

Air Supply Pressure
Operating PXA140B pumps ~35% below max
air pressure may significantly extend pump
life. PXA140B pumps require 20 psi minimum
air pressure. Operation above 7 Bar (100 psi)
may damage the pump and void the warranty.

PXA140B Owner’s Manual

Using Proximity Sensors
Pumps using a proximity sensor are not
intrinsically safe and do not qualify for
use in explosion-proof environments.

Suction Lift
PXA140B pumps have initial suction lift
of 3 ft. For best results minimize suction
lift.

Liquid Inlet/Outlet Connections
PXA140B liquid ports are not NPT nor
any other standard. Use of connectors
other than those supplied by White
Knight will damage the pump and void
the warranty.

Liquid Line Restriction
PXA140B pumps may be controlled
by closing liquid outlet lines. However,
restricting liquid supply lines increases
wear and should be avoided. Do NOT
pump against a closed liquid inlet. It will
damage the pump and void the warranty.

Running Dry
PXA140B pumps use the pumped liquid
to lubricate their shafts. The pumps will
cycle faster and wear more than normal
when run dry, which may cause damage
and loss of self-prime abilities. PXA140B
pumps should not be run dry after startup and are not warrantied under dry run
conditions.

Pulse Dampener with Shuttle Valve
Air supply pressure to PXA140B pumps
should be at least ten psi higher than
the liquid line pressure when using a
pulsation dampener. Failure to do so
may cause erratic operation.

Cross Contamination
PXA140B pumps use porous
material that may retain chemicals.
Take precautions to avoid cross
contamination.

2.2 Warnings
Pressurized Material
Pumps in use contain
pressurized materials.
Eliminate liquid and air
pressure via shut off valves
before pump is serviced or
removed from the system.

High Temperature
Heat may transfer to exterior
surfaces when pumps operate
with high temperature fluids.
Avoid direct contact with the
pump when high temperature
fluids are present.

Hazardous Chemical
Use appropriate personal
protective equipment when
handling pump. Reference
Material Safety Data Sheet
(MSDS) for information
specific to your chemicals.

Loud Noise
Pump exhaust air contributes
to work area noise levels. Only
operate pumps with approved
muffler media, and use ear
protection in noisy conditions.

2.3 Advantages
Head Pressure / Dead-Head
PXA140B pumps can be controlled by
adjusting their liquid outlet pressures and
can be installed with head pressures up
to dead-head (e.g. equal liquid and air
pressures) with no damage to the pump.

Thermal Cycling
PXA140B pumps require no maintenance
when operated within their performance
range, even in thermal cycling applications.

PXA140B Owner’s Manual

2.4 Environment & System
Oversized Inlet Line
Pumps operate optimally with liquid inlet
lines larger than the liquid outlet lines. This
reduces strain on the bellows and may
reduce pulsation in the pump outlet.

Clean Supply Air (CDA)
PXA140B pumps require use of Class 2 air
for particles and moisture per ISO 8573-1.
Use 10 micron filter; maintain -40°C dew
point. A point-of-use filter is recommended
during first six months of operation in new
fabs/systems due to high risks of debris
that can damage pumps and void warranty.

Flammable Solvents
PXA140B pumps are not constructed from
conductive materials. System that pump
flammable solvents should be properly
grounded to avoid ignition by static charge.
A River’s Edge test of isolative pumps with
flammable liquids indicated that liquids
must be grounded and other procedures
should be followed. Copy of test available.

Pumping Liquids Near Boiling Point
Minimizing suction lift reduces pulsation
and the potential for boiling or outgassing
of liquid in the inlet of the pump. Although
reciprocating pumps can pull suction lift,
pump performance and life increase when
suction lift is minimized or eliminated.

Abrasive Slurry
Pumping abrasive slurry may accelerate
wear of components. PXA140B pumps are
warrantied when used with slurry. However,
normal wear is not covered by warranty.

Environmental Temperature
PXA140B pumps are rated for 0°C (32°F) 50°C (122°F) environmental temperatures.
Do not freeze fluid in pump. Operation
below 0°C may accelerate wear. Normal
wear is not covered by warranty.

3.2 Shift Logic for Proximity Pumps
Pump
Startup

Air must be sent to
either side at startup
to initiate movement.

Send air
to left side
of pump

During pump operation, the timing
of the solenoid valve should be
dependent on sensors with no time
delays. There should be no delay
between reading the sensor signal
and actuating the solenoid valve.

Logic

Check
Sensors

Only left
sensor is true

Send air
to right side
of pump

Only right
sensor is true

Air remains on either side
if both sensors are true or false

Proximity End Stroke Operation

* The proximity sensors on the pump can both be seen in the middle of the stroke;
thus it is required that the solenoid not be switched until just one sensor is seen.
* Vertical line denotes when the solenoid was switched.

assembly.

Replace NPT plug in “L”
port with probe. Hand
Tighten. Attach cable to
signal translator (e.g. PLC).

3.

Remove leak adapter and
leak detect probe from
fiber optic assembly.

For straight out configuration
replace NPT plug in “L” port
with the probe. Hand-tighten.

Insert the fiber optic
cable until it contacts
the bottom of the probe.

5.

Lower ferrule and gripper until
snug against the probe. Hand
tighten female gripper nut.

Open the top and slide the front face of the D10 up.
Press the fiber optic ends into the holes on its front.
Slide the face down to lock cables in place.
