Spray Area Explosion Hazard—
Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1, Trichloro-
ethane are not chemically com-
patible with the aluminum that
might be used in many system
components. The chemical re-
action caused by these solvents
reacting with aluminum can be-
come violent and lead to an
equipment explosion.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equip-
ment during spraying, flushing, or cleaning. Read
the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating
or cleaning material is compatible, contact your
coating supplier. Any other type of solvent may be
used with aluminum equipment.

GENERAL INFORMATION
The displacement pump (Gear Pump) is used on the RCS and RCS-2 systems. Pumps are
mounting directly to either a resin manifold (for the flushable pump unit) or a catalyst
manifold (for the non-flushable pump). Typical torque applied to the mounting bolts should
not exceed 17 lb-ft (23 N-m). Excessive torque can lead to pump seizure and internal
pump damage. Always follow specified torque settings.

Positive Displacement Pump - Operation
LN-9415-01 10
OPERATION
If the inlet pressure of the pump is too low,
the pump will be starved for material and
will cavitate, resulting in lower flows than
expected. Additionally, if the outbound
pressure is significantly higher than the inlet
pressure, the gears will slip by the material,
also causing the flow to be less than ex-
pected.
On the other hand, if the inlet pressure is
too high (especially at low viscosities),
material can “blow by” the gears in the
meter and the resultant flow will be higher
than expected.
Positive displacement gear pumps are most
accurate when the pressure across the
pump (known as differential pressure) is
minimized. That is, if the inlet pressure can
be maintained at a pressure that is very
close to the outlet pressure, the most
accuracy will be realized. The RCS and
RCS-2 Systems have the ability to control
the inlet pressure automatically based on
the value of the outlet pressure. This,
however, is an optional feature. If you are
interested in enabling this feature on your
RCS or RCS-2 System, contact your
Ransburg representative.
PRINCIPLE OF OPERATION
The external gear pump is a positive dis-
placement (PD) type of pump generally
used for the transfer and metering of liq-
uids. The gear pump is a precision machine
with extremely tight fits and tolerances, and
is capable of working under high differential
pressures.
Typically there is a drive gear driven by a
motor that rotates an idler gear in the
opposite direction. When the gears rotate,
the liquid, which is trapped in the gear teeth
spaces between the housing bore and the
outside of the gears, is transferred from the
inlet side of the pump to the outlet side. The
pumped liquid moves around the outside of
the gears and not between the gears. The
rotating gears continue to deliver a fresh
supply of liquid from the suction (inlet) side
of the pump to the discharge (outlet) side of
the pump, with virtually no pulsations. The
meshing of the gears on the discharge side
of the pump forces the liquid out of the
pump and into the discharge port.
Flow rate through the pump is controlled
simply by varying the RPM of the motor
driving the pump. On RCS and RCS-2
Systems, it is recommended that the RPM
of the pump not be allowed to exceed 150
RPM’s.
The accuracy of the gear pump is directly
affected by both the viscosity of the material
being pumped and the differential pressure
across the pump.
If the material is too thin (e.g. viscosities
less than 30 centipoise), it will not be
properly metered by the pump and inaccu-
rate flow rates will result.

MAINTENANCE
CALIBRATION
The calibration value will vary based on
viscosity, flow rate, temperature, and other
factors. Refer to appropriate associated
equipment for calibration procedure.
TROUBLESHOOTING
Gear Pump problems can be caused by
improperly filtered fluid. Particulates in the
fluid can cause gear binding. Maintain the fluid
filters according to the instructions from the
filter manufacturer. If repeated disassembly
and cleaning for removal of solids and particu-
lates occurs, inspect the entire fluid supply
system and evaluate the system cleaning
cycle.
SERVICING
Depressurize the gear pumps before attempt-
ing to remove from manifold. Remove the gear
pump for service to a suitable clean area to
perform maintenance. Using a hex key
wrench, remove all 4 bolts. See pages 11-15
for teardown and reassembly procedures for
both series of gear pumps.
