WARNING
EXCESSIVE INLET PRESSURE. Can cause explo-
sion resulting in severe injury or death. Do not exceed max-
imum operating pressure of 7500 p.s.i. (517.2 bar) at 150
p.s.i. (10.3 bar) inlet air pressure. Do not run pump without
using a regulator to limit air supply pressure to the pump.
PUMP RATIO X INLET = MAXIMUM PUMP
PRESSURE TO PUMP MOTOR FLUID PRESSURE
Pump ratio is an expression of the relationship between the pump motor area
and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure
is supplied to the motor of a 50:1 ratio pump, it will develop a maximum of 7500
p.s.i. (517 bar) uid pressure (at no ow) - as the uid control is opened, the ow
rate will increase as the motor cycle rate increases to keep up with the demand.
WARNING
EXCESSIVE MATERIAL PRESSURE. Can cause
equipment failure resulting in severe injury or property
damage. Do not exceed the maximum material pressure of
any component in the system.
Thermal expansion hazard. This can occur when the fluid in
the material lines is exposed to elevated temperatures. Ex-
ample: Material lines located in a non-insulated roof area
can warm due to sunlight. Install a pressure relief valve in
the pumping system.
AIR AND LUBE REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the
pump to operate more efficiently and yield longer service life to
moving parts and mechanisms.
Use an air line lter to provide good quality clean and dry air.
Install it up stream from the air regulator.
Use an air regulator on the air supply to control the pump cycle
rate. Install the regulator as close as possible to the pump.
In most installations, lubrication is not required. If the pump
needs to have lubrication, install an air line lubricator between
the pump and the air regulator and supply it with a good grade
of non-detergent oil or other lubricant that is compatible with
Nitrile seals. Set at a rate not to exceed one drop per minute.
INSTALLATION
Assemble the components included in the package as shown in
gure 1 (page 1). NOTE: In rigid plumbing applications, use exible
material and air supply hoses when attaching the pump to prevent
damage by vibration.
Thread the pump bung adapter into the pump cover. Insert the
pump into the bung and then secure with the thumb screws
provided.
Install the outlet adapter, material hose, swivel and gun.
Lay the follower on top of a full bucket of grease. Feed the
lower pump end into the follower and secure the cover with
the thumb screws.
Attach a connector to the pump and a coupler to the air supply
hose.
Connect the material hose to the pump outlet. Tighten all t-
tings. Use caution not to damage threads.

OPERATING AND SAFETY PRECAUTIONS
OPERATION
START-UP
Turn the air regulator to "0" pressure setting. Connect the air
hose.
Prime the pump by cycling slowly, raising the pressure to 20 -
30 p.s.i. (1.4 - 2.1 bar). Cycle the pump until the test grease and
any trapped air has been purged from the system.
Close the dispensing device. Allow the pump to build line
pressure and stall. Check for any leaks and re-torque ttings if
needed. Adjust the air pressure upward as required for the ap-
plication.
NOTICE: If the pump does not prime soon after initial start-up, es-
tablish what the problem is to prevent unnecessary damage to the
pump plunger.
SHUTDOWN
Disconnect the air supply from the pump if it is to be inactive
for a few hours. Open the dispensing device to relieve line pres-
sure.
SERVICE
Refer to the basic pump manual for service instructions which also
cover disassembly and reassembly for installation of the rebuild kit.
TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
Be certain to check for non-pump problems including kinked,
restrictive or plugged inlet / outlet hose or dispensing device.
Depressurize the pump system and clean out any obstructions
in the inlet / outlet material lines.
Check all seals, including track gaskets.
Check direction of "U" cup lips.
