3 Pump Warranty
White Knight Fluid Handling follows strict procedures in all phases of manufacturing, assembly,
and testing to ensure reliability of its products. Each pump is individually tested to assure its
functional operation integrity.
White Knight Fluid Handling warrants the PPMC300 pump, subassemblies and components to
be free from defects in materials and workmanship to 6 months from date of start-up, or 8
months from the date of shipment, whichever occurs first. Failures due to misuse, abuse or
any unauthorized disassembly of a White Knightpump will nullify this warranty.
The PPMC300 metering pump is warranted for up to 100 PSI air supply pressures, and 160
PSI discharge pressures. Wearable parts are not covered if used to pump abrasive slurries.
Due to the broad and ever-evolving applications for usage of White Knightpumps we cannot
guarantee the suitability of any pump component or subassembly for any particular or specific
application. White Knight Fluid Handling shall not be liable for any consequential damage or
expense arising from the use or misuse of its products in any application. Responsibility is
limited solely to the replacement or repair of defective White Knightpumps, components or
subassemblies. All options to rebuild or replace aforementioned items shall remain under the
judgment of White Knight Fluid Handling. Decisions as to the cause of failure shall be solely
determined by White Knight Fluid Handling.
Prior written, faxed or emailed approval must be obtained from White Knight Fluid Handling
before returning any pump component or subassembly for warranty consideration.
THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER
WARRANTIES EXPRESSED OR IMPLIED INCLUDING ANY WARRANTIES OF
SUITABILITY FOR ANY PARTICULAR PURPOSE. NO VARIATIONS OF THIS WARRANTY
BY ANYONE OTHER THAN THE PRESIDENT OF WHITE KNIGHT FLUID HANDLING IN A
SELF-SIGNED AGREEMENT SHALL BE HONORED OR CONSIDERED LEGALLY BINDING.

4 Installation and Precautions
4.1 Precautions
Use of Electronically Controlled Dispense Pumps
Electrically controlled dispense pumps do not qualify for use in explosion proof environments.
Handling
DO NOT LIFT PUMP BY LIQUID FITTINGS OR AIR TUBING!
Air Supply
The operation of the PPMC300 requires a minimum of 20PSI air supply pressure, ran through a minimum ⅛” ID
airline. Max air supply pressure is 100 psi. The pump operates with a pressure multiplier; discharge pressure can
exceed supply pressure (100PSI supply equals up to 160PSI discharge)
Dry Priming/Air Purging
For optimal performance of this pump the pump should be primed with liquid until no air is found in the
liquid dispense line. Mounting the pump in a vertical position, with the liquid inlet pointed down, and the
liquid outlet pointed up, is recommended.
Pumping Slurries and Abrasives
This pump is not recommended for pumping slurries or abrasives. Pumping abrasives will shorten the
life of the pump.
Restriction of Liquid Inlet Line
Restricting the liquid supply of the pump forces the pump to work harder than normal and should be
avoided when possible.
Cross Contamination
PTFE and many other plastics are very porous and may retain chemicals in the pores of the material. Record
chemistries used in a pump to avoid cross contamination.
WARNING: Liquids and Gasses Under Pressure
While in a live system, pumps contain pressurized liquids and gasses. All pressure,
liquid and air must be eliminated via shut off valves before the pump may be removed
or detached from the system.
WARNING: Handling of Chemicals
In the event that hazardous chemicals are used in or around the pump, ensure that
appropriate personal protective equipment is used before handling. Reference the
chemistry’s Material Safety Data Sheet (MSDS) for handling instructions or other
information specific to that chemical.
NEMA 5 Applications
The PPMC300 is capable of NEMA 5 classification. However, this requires that the end user route the vent air to a
safe location. The port is located on the front of the pump housing and is assembled and shipped with an orifice
plug to allow for immediate use upon arrival. The exhaust must remain clear of obstruction, or the motor housing
cover will disengage. The exhaust port is ⅛” NPT, recessed in the motor housing.
Liquid Fittings
The liquid fittings on this pump use tongue and groove seals and contain check valves. Over-torque of the fittings
will damage the threads and reduce the performance. Because of this, the fittings are pinned in place. Rotation
after initial assembly will damage the fittings. Always use a backer wrench when applying torque to fittings.
Do not Disassemble These Fittings Without Prior Training From White Knight.

4.2 System and Pump Environment Recommendations/Requirements
4.3 Installation Advantages
Clean Supply Air (CDA)
White Knight high purity pumps require the use of Class 2 air for particles and moisture per ISO 8573-1. (Use 10-
micron filter, maintain -40° C dew point)
Environmental Temperature
This pump is rated to withstand environmental temperatures up to 80°C.
High Discharge Pressure
The PPMC300 is capable of discharging at pressures up to 160 psi. Max air supply is 100 psi.
Mounting Orientation
The PPMC300 can be mounted in any orientation. For optimal air purge, resulting in highest repeatability, the
pump should be mounted such that the fluid flows vertically.

4.4 Installation Instructions
Decide where the pump is to be mounted. For
optimal performance mount the pump such that
the fluid path flows uphill (with air and power
connections pointing down as shown in the
Images to the right).
Drill and tap 3 #6-32 holes using the baseplate
dimensional for positioning the holes.
Insert #6-32 socket head cap screws into location
for the key slot holes. Leave enough room for
base plate to slide under screw cap; about ¼”.
Slide pump into position using the key slot hole to
help hold pump in place.
Insert and tighten the remaining 2 #6-32 socket
head cap screws into position on opposite side of
pump.
Tighten the key slot screws.
The pump is now secured.
Attach liquid fittings inlet on the side with the air
and electrical connections, and the outlet on the
opposite side. Use a backer wrench so that the
fitting is not damaged.
Attach electrical connector to the M12 Turck male
receptacle.
Attach air pressure to the CDA inlet port using 1/8”
FNPT port.

4.5 Connections
The pump has 5 connections:
•Fluid Inlet Port: This port is to be connected to the fluid reservoir that is to be pumped. Standard Flaretek
and Pillar compatible options available. See ordering instructions.
•Fluid Outlet Port: This is the pump outlet and should be connected to where the pump is to pump the
fluid. Standard Flaretek and Pillar compatible options available. See ordering instructions.
•Exhaust Air Port: This port is to vent the exhaust air from the pumping operation. An orifice NPT plug is
connected to this port by default. If the user wants this air to exhaust to a remote location then the orifice
plug can be removed and connected to a tube via the 1/8” FNPT port. Do not plug this port.
•CDA Input: This port is to supply the CDA input pressure. The pump will use this air pressure to
pressurize the discharge liquid. The discharge liquid pressure will be 6 times the CDA input pressure. Air
fitting is a 1/8” FNPT port.
•Power & I/O Port: This is the electrical power port that supplies power to the on-board controller and to
the I/O. More information on the pin out and controls is found in section 6. Connection type male M12 5-
pin receptacle made by TURCK.
