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.
