Product Usage Instructions

1. Installation

Before installing your White Knight product, please carefully
review the product manual. Follow the instructions below for proper
installation:

Choose a suitable location for the pump.
Ensure that the pump is placed on a stable and level
surface.
Connect the necessary hoses and fittings as per the provided
diagrams.
Check all connections for leaks and tighten if necessary.

2. Setup

Once the pump is installed, follow the steps below to set it
up:

Ensure that the air supply is connected and the pressure is
within the specified limits (30 psi to 100 psi).
Adjust the air pressure regulator to the desired operating
pressure.
Prime the pump by filling the suction line with the liquid
being pumped.
Turn on the power and activate the pump.

3. Operation

To operate the White Knight PSD16 Pump, follow these
guidelines:

Monitor the flow rate and adjust the air pressure as needed to
achieve the desired flow.
Regularly check the pump for any signs of leaks or abnormal
noises.
Ensure that the maximum size of passible solids (6 mm or 0.24
in) is not exceeded to prevent damage to the pump.
Operate the pump within the specified temperature range to
maintain optimal performance.

4. Maintenance

To keep your White Knight product in good working condition,
perform regular maintenance tasks:

Clean the pump and its components regularly to remove any dirt
or debris.

Refer to the product manual for detailed maintenance
instructions and recommended maintenance schedule.

FAQ

Q: Can I operate the pump with a different air supply

pressure?

A: It is recommended to operate the pump within the specified
air supply pressure limits of 30 psi to 100 psi. Operating outside
of this range may affect performance and could potentially damage
the pump.

Q: What should I do if I notice a leak?

A: If you notice a leak, first ensure that all connections are
tight. If the leak persists, shut off the pump and inspect the
affected area for any damaged parts or worn-out seals. Replace any
faulty components as necessary.

Q: How often should I perform maintenance on the pump?

A: Regular maintenance is important to ensure optimal
performance and longevity of the pump. Refer to the product manual
for detailed maintenance instructions and recommended maintenance
schedule.

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 and fluid temperatures. See torquing instructions on page 17.

3 Installation
3.1 Installation Precautions
Required Air Flow and Operating Pressure Required Air Flow for the PSD16 is 3/8″ 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 PSD16 is 7 Bar (100 PSI).
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.

3.2 PSD Installation Advantages
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.
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 CatcherTM 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.
3.3 System and Pump Environment
Clean Dry Supply Air (CDA) Operation of the point of 5 PSD16 requires class 4 quality air for particles, moisture, and oils. (maximum particle size 15 microns, 3° C Dew 5 mg/m) 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.

Abrasive Slurries For slurry applications White Knight recommends use of the PSD UH pump.
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.
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).

4.5 Torque Instructions

Tie Bolts

Crossover Bolts

Tie bolts (purple) on both sides must be torqued before manifold bolts (blue) on top and bottom.

Torquing of head bolts should be done in a crossing fashion such as: 1, 6, 8, 3, 5, 10, 2, 7, 4, 9.

Torquing of manifold bolts should be done in a crossing fashion such as 13, 11, 12, 14, 17, 15, 18, 16.
Apply Loctite Antiseize Lubricant LB 8012 (or equivalent) to all bolts. This procedure must be followed for assembly and also re-torquing of bolts.
