SureFire II Lubricator
Quick Start Manual
PDI Operation
The SureFire II PDI Lubricator has a motor-driven pump that
pulls lubricant in from the reservoir and delivers pressurised
lubricant to the distribution network through the outlet(s) in
the top plate. Pressurising the distribution network forces all
of the positive displacement injectors (PDIs) in the system to
fi re, discharging the lubricant that was stored in each of their
discharge chambers during the last pump cycle.
The pressure in the main line continues to rise activating the
pressure switch until relief pressure is reached, at which
stage, the relief valve opens and discharges the pressurised
lubricant back into the reservoir. The pressure switch can be
used to stop the motor, and momentary pressure in the main
line becomes greater than the pressure at the outlet side of
the gear pump. This pressure differential actuates a quick
dump valve which relieves the main line pressure back into
the reservoir.
SLR Operation
The SureFire II SLR Lubricator has a motor-driven pump that
pulls oil in from the reservoir and delivers pressurized oil to
the distribution network through the outlet(s) in the top
plate. Pressurizing the distribution network forces all of the
resistance fi ttings in the system to discharge the oil in
proportioned quantities to the friction points. The resistance
fi ttings continue to fl ow and the pump builds pressure until
pressure relief valve setting is reached (75 psi/5 bar). Once
the motor is shut off, pressure in the distribution network
returns to near 0 psi via a quick dump valve.
Installation and Commissioning
Install the SureFire II Lubricator in the
horizontal position ONLY. Attach the lubricator in the desired
location and to the desired equipment by means of an
appropriately sized bolt through each of the (2) mounting
holes in the top plate. (2L & 3L=M6, 6L=M8) The lubricator
should be installed in a location that is easy to access, for
purposes of viewing the front panels, for ease of
reservoir-fi lling, for ease of service and for ease of
attachment to the distribution network plumbing.
Remember the SureFire II lubricator allows attachment of
distribution plumbing to either (or both) sides of the top
plate. If only one side is used, be sure to plug the unused
outlet with a G1/4 BSPP plug (two plugs are included with
each lubricator).
Two liquid tight fi ttings are supplied with the lubricator. Use
the liquid tight fi ttings to secure the electrical wiring for the
lubricator and to prevent ingress of fl uids or dirt getting into
the motor compartment. Typically one of the fi ttings is used
to bring “power” into the motor compartment and the other
fi tting is used to bring “signal” into or out of the motor
compartment.
All tubing, fl exible hoses and fi ttings must be compatible with
the lubricant, operating pressure and surrounding
environment. In general, try to install the lubricator in the
lowest position (vertically) with relation to the rest of the

All safety and/or warning labels affi xed to the SureFire II

distribution network and do not allow the tubing to rise and
fall when avoiding obstacles. This is in case air enters the
distribution lines, the bubbles will tend to rise towards the
end of the distribution lines and not get caught anywhere
along the way. Any air bubbles trapped in the distribution
network plumbing may prevent the PDI injectors from
working properly.
All electrical connections are
to be made by a qualifi ed technician and all local electrical
codes are to be followed. When electrical connections are
being made, do so before the power leads are connected and
before the power is supplied.
Consult the wiring diagram (located under the motor cover)
for the correct wiring for your SureFire II lubricator.
The installation should provide
a means of disconnecting the power supply for servicing.
Such means shall allow for switching off the power during
normal operation and/or in an emergency. Also, a residual
current device is required to automatically disconnect the
power supply in the event of a failure in basic insulation.
This emergency disconnecting switch should be located in
close proximity to the equipment and within easy reach. The
switch should be marked as the disconnecting device of the
equipment and have ON/OFF positions clearly identifi ed. It
should also meet the requirements of IEC60947-1 or
IEC60947-3.
Be sure that all plumbing distribution lines are clean, are not
kinked and are free from any chips or any other impurities.
Fill the reservoir through the fi ll cap and/or
fi ll cap strainer with clean lubricant specifi ed by the Original
Equipment Manufacturer and that meets all of the lubricant
specifi cations to the right.
Do not overfi ll the reservoir. Never fi ll past
the “MAX” level as noted on the reservoir. Overfi lling could
cause damage to the electrical components located under
the motor cover.
Pump Priming
Filling the reservoir and turning on the lubricator is usually
enough to prime the pump. However, in the case of a very
thick lubricant, sometimes it’s necessary to assist priming
the pump. Upon initial start-up, if no lubricant is being
delivered to the pump outlet, make sure the pump is primed.
Avoid all kinds of impurities as dirt particles are the most
common cause of gear pump failure. If you wish to determine
whether the lubricant you plan on using is approved for use
with Bijur Lubricating Systems, you can consult the Customer
Service Department.
To prime the distribution network, plumb the entire system
(mainline tubing, manifolds, junctions, air/oil blocks, injectors,
injector outlet tubing to bearing points, meter units etc.).
Then, remove a plug or injector at the point furthest away
from the pump. Now, run the pump until bubble-free lubricant
fl ows from this point. Replace the plug or last injector.
Lubrication Specifi cations:
Standard Oil version:
20 to 1500 cSt @ operating temperature
Light Oil version:
5-40 cSt @ operating temperature
Grease version (PDI only):
NLGI grade 000 - 00 (40,000 cSt max)
Motor Duty Cycle:
100/115VAC and 200/230VAC motors: S3, 20%, 15 Min.
This means that the maximum continuous “on time” for
any cycle is 3 minutes, and if the motor continuous “on
time” for a cycle is X, the required minimum “off time”
for that same cycle is at least 4X. Each motor has an
internal high temperature cut-off switch.
24 VDC motor: S1, Continuous Duty
