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-torqueing 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 and fluid temperatures.

See torqueing instructions on page 16.

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 that 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 PSD24 is ⅜” minimum orifice unrestricted at 2 meters lengths or lower, larger

lengths may require a larger diameter for full flow. An adaptor is included for ½” NPT or ½” BSPT with

all pumps, NPT or BSPT is decided on based on the liquid fittings requested. Max air supply for the

PSD24 is 7 Bar (100 PSI).

435.783.6040 888.796.2476

3.2 PSD Installation Advantages

3.3 System and Pump Environment

Clean Dry Supply Air (CDA)

Operation of the point of 5 PSD24 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.

4.3 Configurable Rebuild Ordering Instructions

Pages 12 and 13 list the standard rebuild kits White Knight offers. Use this section for alternate rebuild kits not

found in the previous section.

Air Motor

Air Motors do not need to be removed from the

pump for service. However, complete air motors

with all components (tested and certified) are

available from White Knight. They can be removed

and installed in the pump body as shown in the

figure using the air motor pin wrench tool. (Rotate
