SAFETY AND HANDLING
4
WARNING! The design and configuration of the PH Series
Proportioner does not allow its use in potentially explosive
atmospheres, or the pressure and temperature limits
described in the technical specifications of this manual to be
exceeded.
Always use liquids and solvents that are compatible with the unit. If in doubt, consult your PMC
Distributor.
When working with the PH Series Proportioner, it is recommended that the operator wear
suitable clothing and elements of personal protection, including, without limitation, gloves,
protective goggles, safety footwear, and face masks. Use breathing equipment when working
with the PH Series Proportioner in enclosed spaces or in areas with insufficient ventilation. The
introduction and follow-up of safety measures must not be limited to those described in this
manual. Before starting up the PH Series Proportioner, a comprehensive analysis must be
made of the risks derived from the products to be dispensed, the type of application, and the
working environment.
To prevent possible injury caused by incorrect handling of the raw
materials and solvents used in the process, carefully read the
Material Safety Data Sheet (MSDS) provided by your supplier.
Deal with the waste caused according to current regulations.
To avoid damage caused by the impact of pressurized fluids, do
not open any connection or perform maintenance work on
components subject to pressure until the pressure has been
completely eliminated.
Use suitable protection when operating, maintaining or being
present in the area where the equipment is functioning. This
includes, but is not limited to, the use of protective goggles,
gloves, shoes and safety clothing and breathing equipment.

CHARACTERISTICS
The Classic PH Series Proportioner has been designed and built for the application of
polyurea chemical systems, polyurethane foam chemical systems, and some specific two-
component epoxy systems.
PRINCIPAL HEATING SYSTEM
The Proportioners consist of two (2) independent Material Heaters without internal seals. Each
heater for the PH(X)-25 Proportioner has four (4) Heating Elements rated at 1,000, 1,250 or
1,500 watts, each giving the Proportioner a total heat of 8,000, 10,000, or 12,000 watts. Each
heater for the PH(X)-40 Proportioner has six (6) Heating Elements rated at 1,250 1,500 or 1,750
watts each, giving the Proportioner a total heat of 15,000, 18,000 or 21,000 watts. The Material
Heater systems for all PH Series Proportioners contain the necessary control and safety
components for their precise operation. The Material Heater design allows a temperature
differential (ΔT) of 90ºF (32ºC) and material application temperatures of up to 190ºF (88ºC)
under normal ambient temperatures.
HOSE HEATING SYSTEM
The PH(X)-25 Proportioner is designed with a 3 KVA (90 V) Isolation Transformer that enables
effective heating of up to a total hose length of 310 feet (94 meters). The PH(X)-40 Proportioner
is designed with a 5 KVA (120 V) Isolation Transformer that enables effective heating of up to a
total hose length of 410 feet (123 meters). Both systems include an innovative hose heating
concept in which the continuous braid tinned-copper jacket is distributed evenly around the
circumference of the hose providing a uniform heating watt density and precise control of the
material application temperature. This hose heating element design is extremely resistant to
fatigue failure.
100% circumferential coverage produces the most
uniform distribution of heat available.
DOUBLE ACTING OPPOSED PISTON METERING PUMPS
The opposed double acting Pump Line is driven by a dual rod Hydraulic Cylinder. The in-line
pump system with opposed piston pumps provides a constant volume and guarantees uniform
pressures in both directions of pump movement. Different sized pumps allow for various
volumetric ratios to be achieved (1:4 to 1:1 to 4:1) between the chemical components used in
the process.

CHARACTERISTICS
6
PRESSURE BALANCE CONTROL SYSTEM
The Pressure Balance Control (PBC) system provides better control over a chemical pressure
imbalance. When the system is turned off, the Proportioner will perform as if there is no PBC
system and will continue pumping material. When the system is turned on, it will continually
monitor the pressure between the two chemicals (known as the pressure differential). If the
pressure differential becomes equal to or greater than the maximum allowable pressure
differential, the pumps will be shut off.
The Pressure Balance Control system can be simplified into a logic box diagram with inputs and
outputs. There are five inputs: the power supply from the main console, the pressure readings
from each chemical, the maximum pressure, and the maximum allowable pressure differential.
Inside the logic box, the actual pressure differential of the chemicals is compared to the
maximum allowable pressure differential. Depending on the circumstances of all five inputs,
there are only two possible outputs: either the pumps will continue to pressurize and move
material, or the pumps will shut off and flow will be lost.
