STORAGE
PSD pumps that are not put into operation upon delivery must be stored in an environment where they are
protected from moisture, extreme temperatures, UV radiation, vibration, and should be kept clean. White Knight
recommends an environment of ambient temperature (between 60°F (15°C) and 80°F (25°C)) with a humidity
level below 65%.
Maintenance and Torque Values
Upon installation of the pump, as well as after a few hours of operating the pump, the head and manifold bolts
must be re-torqued. Tie bolts and manifold bolts must be re-torqued to values specified in the table below.
Re-torquing will be required after the pump has set for extended periods of time, run in thermal cycling
applications, been dismantled, or when there is a large difference between environmental temperatures and fluid
temperatures. See torquing instructions on page 17.

3 Installation
3.1 Installation Precautions
Restriction of Liquid Inlet Line
Restricting the liquid supply of the pump forces the pump to work harder than normal and should be
avoided whenever possible, especially when pumping viscous liquids. Attempting to operate the pump
against a closed liquid inlet will cause serious damage to the pump, and will void the warranty. If you
wish to slow or stop your pump this may be done by closing off the liquid outlet.
Supply Pressure Recommendations
The life of your pump may be extended significantly by operating your pump 30%-40% below redline
operating supply pressures. The use of undersized regulators, valves, and supply lines can decrease
pump performance and longevity significantly.
Orientation
White Knight does not recommend installing your pump in any position other than its upright position.
Check valves within White Knight PSD pumps are actuated by gravity and/or flow and perform optimally
in the upright position.
Failure Potential
It is possible that the diaphragm may fail. In such a situation it is possible that chemical could enter the
air side of the pump, and may even escape through the muffler. In such a situation the muffler media
must be replaced and the air side purged. White Knight recommends the implementation of a one way
valve on the air side to protect air lines from contamination in the event of a diaphragm failure.
Muffler
Pump performance may be restricted in the event of a clogged muffler. Regular inspection of air lines
and muffler media is recommended to maintain performance.
Product Testing
Each pump is tested before being packaged for shipment. White Knight recommends the flushing of
each pump before servicing if water can contaminate the process.
Required Air Flow and Operating Pressure
Required Air Flow for the PSD08 is 1/4” minimum orifice unrestricted. An adaptor is included for ¼”NPT
or ¼” BSPT with all pumps, NPT or BSPT is decided on based on the liquid fittings requested. Max air
supply for the PSD08 is 7 Bar (100 PSI).

3.2 PSD Installation Advantages
3.3 System and Pump Environment
Clean Dry Supply Air (CDA)
Operation of the point of 5 PSD08 requires class 4 quality air for particles, moisture, and oils.
(maximum particle size 15 microns, 3° C Dew 5 mg/mᵌ) per ISO8573 –1.
Flammable Solvents
Any system used to pump flammable solvents should be properly grounded. A test from River’s Edge
on using isolative pumps to pump flammable liquids indicated that the liquid itself must be grounded
and that other procedures should be followed. A copy of the test is available upon request from
White Knight.
Pumping Liquids Near Boiling Point
The boiling point of a liquid is reduced under vacuum (suction) conditions. Due to the vacuum caused
by a pump, liquid could boil in the inlet line of the pump when it is not boiling in the tank (or other supply
reservoir). Placing the pump as close as possible to the tank and with as little vertical lift as possible
(the pump being flooded by gravity is ideal) minimizes boiling in the inlet line. Boiling of the liquid in the
inlet line causes a pump to “race” and accelerates the wear of the pump. Boiling liquids may cause
cavitation to occur. Damage to wearable or non-wearable components of the pump caused by cavitation
is not covered under warranty.
Abrasive Slurries
For slurry applications White Knight recommends use of the PSD UH pump.
Passing Solids
All damage caused by passing solids (wafer shards, etc.) is coverable under warranty when your pump
is used in conjunction with a White Knight Catcher™ pre-pump filter.
Running Dry
White Knight PSD pumps are capable of running dry without damage other than normal wear to the
pump. When a pump is run dry it cycles faster than normal, accelerating the rate of normal wear.
Head Pressure / Dead-Head
White Knight PSD pumps may be controlled by opening and closing the outlet of the pump and may be
installed in any head pressure situation up to dead-head. Dead-head occurs when air supply pressure
and the liquid line (head) pressure are equal. Dead-head conditions allow for no flow. Under dead-head
conditions the PSD will cease to cycle (limiting wear) until conditions change allowing for flow.
Running a Submerged Pump
When running the PSD in submerged mode, the exhaust air must be sealed and redirected above the
surface of the media. Take care that all pump parts (air side and wet side) are resistant to the media
being used. It may be necessary to mount the pump to the bottom of the tank. Operating this pump
while submerged requires use of a remote muffler adaptor kit.
Temperature
The PSD may be operated safely in low temperature applications. Take care to avoid freezing or
crystallization of the fluid inside or outside of the pump. Running the pump at temperatures below
freezing may accelerate the wear of the elastomer components within the pump. In applications where
the media or pump temperature varies, torque values (tension) of the manifold and head bolts must be
monitored. TE versions of the PSD Series pumps can be operated at temperatures up to 100°C
(212° F). UH versions of the PSD Series pumps can be operated at temperatures up to 70°C (158°F).

3.4 Control and Monitoring Connections
•PUMP MONITORING: Pump monitoring can be performed by solid state pressure switch monitoring.
This option is described on our website in the accessories section and is available for new orders and
for retrofits in the field.
•Pump Control: Run mode and flow rate are two of the items which the CPT-1 can control/monitor.
Pressure Switch Stroke Detection
Conductivity Leak Detection

Tie bolts (purple) on both sides must be torqued before
manifold bolts (blue) on top and bottom.
Torquing of tie bolts should be done in a crossing fashion
as shown in image. There is no particular order for
torquing manifold bolts other than they must be done after
head blots.
