PLACING INTO SERVICE
WARNING
EXCESSIVE INLET PRESSURE. Can cause exĆ
plosion resulting in severe injury or death. Do not exceed maxiĆ
mum 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 PRESSURE TO PUMP MOTOR
=
MAXIMUM PUMP
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) fluid pressure (at no flow) − as the fluid control is opened, the flow 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 damĆ
age. Do not exceed the maximum material pressure handling
capability of any component in the system.
Thermal expansion hazard. This can occur when the fluid in the
material line is exposed to elevated temperatures. Example:
Material line located in a nonĆinsulated roof area can warm due
to sunlight. Install a pressure relief valve in the pumping sysĆ
tem if this condition could exist.
AIR AND LUBRICATION REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the pump to opĆ
erate more efficiently and yield longer service life to moving parts and
mechanisms.
• Use an air line filter 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 nonĆdetergent oil
or other lubricant compatible with Nitrile seals. Set at a rate not to
exceed one drop per minute.
INSTALLATION
Assemble components included in the package as shown in figure 1
(page 1). NOTE: In rigid plumbing applications, use flexible material and
air supply hoses when attaching the pump to prevent damage by vibraĆ
tion.
1. Thread the pump bung adapter into the pump cover, insert the pump
into the bung and then secure with the thumb screws provided.
2. Install the outlet adapter, material hose, swivel and gun.
3. 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.
4. Attach a connector to the pump and a coupler to the air supply hose.
5. Connect the material hose to the pump outlet. Tighten all fittings.
Use caution not to damage threads.
OPERATION
STARTĆUP
1. Turn the air regulator to 0" pressure setting. Connect the air hose.
2. Prime the pump by cycling slowly, raising the pressure to 20 Ć 30
p.s.i. Cycle the pump until the test grease and any trapped air has
been purged from the system.
3. Close the dispensing device. Allow the pump to build line pressure
and stall. Check for any leaks and reĆtorque fittings if needed. Adjust
the air pressure upward as required for the application.
NOTICE: If the pump does not prime soon after initial startĆup, establish
what the problem is to prevent unnecessary damage to the pump plungĆ
er.
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 pressure.
SERVICE
Refer to the basic pump manual for service instructions which also covĆ
ers disassembly and reassembly for installation of the rebuild kit.
TROUBLE SHOOTING
If the pump does not cycle or will not deliver material.
• Be certain to check for nonĆpump problems including kinked, restricĆ
tive 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.
