WARNING
WARNING: The Lion HP®50:1 pump
(1150-015,-018) develops 7500 psi (517
Bar) maximum working pressure at 150 psi
(10.3 Bar) maximum inlet air pressure and
stall conditions. Be sure that any components
or accessories used in the system are rated to
withstand this pressure. To estimate uid output
pressure at stall conditions, multiply the ratio of
the pump by the air pressure being used.
EXAMPLE: 50:1 Pump Ratio x 100 psi air
pressure = 5000 psi uid pressure at stall.
WARNING
Pressure Relief Procedure:
Follow this procedure whenever you
shut off the pump, when checking or servicing
any part of the system and when installing,
cleaning or changing any part of the system.
1) Disconnect the air to the pump.
2) Point dispensing valve away from yourself
and others.
3) Open dispensing valve until pressure is
relieved.

pumping to distances of up to 300 feet.
The Lion HP® air motor features a precision air valve mechanism with dual valve ports for improved high speed
breathing. It also contains a positive trip detent spool mechanism that eliminates stalling (blowing air) by pre-
venting the pump from stopping between strokes. It has a simple yet durable construction with all internal parts
lubricated at the factory using a life-tested synthetic grease.
The Lion HP®pumping assembly features a stainless pump rod for superior wear and corrosion resistance.
The pump's exterior is constructed from aircraft grade aluminum for an outstanding strength and reliability. The
pump also has high quality seals and is designed for long-term durability and ease of service. It also features a
double action grease pumping assembly, which provides volume delivery on both strokes.

To insure proper performance of your grease pump,
Balcrank®recommends using a follower plate if
mounting the pump to a grease drum.
Using four 3/8"-16 bolts and lock washers, secure
the pump to the drum cover. Slide the follower
plate up the pump tube and attach optional screen
assembly. Insert pump (with follower plate) into drum
and tighten thumb screws.
Tighten one end of outlet hose to pump outlet.
Secure control handle to the other end of the outlet
hose.
Install a coupler or a ball valve into the pump's air
intake port. Attach a F-R-L onto the pump. Fill the
lubricator with 10-20 wt. lubricant - set for 1 drop
every 2 hours. Connect compressed air to F-R-L and
set regulator to no more than 150 psi (10 Bar).
Open control handle into suitable container to
properly prime pump and remove air from system.
Pump Installation
CAUTION: Performance will be affected by
a suction path seal (follower plate) that is not
air tight.
WARNING: Attach a proper ground wire
to the pump grounding lug (item 62) before
starting the pump.

The Lion®grease pump has been designed to operate
dependably with little required maintenance. However,
to ensure pump longevity, the following should be
observed:
Keep the grease free of trash and debris.
Periodically check the pump inlet for foreign
matter and clean when necessary.
Run the pump at the minimum pressure required
to achieve the desired ow rate (less than 125
psi and 150 cyc/min recommended).
Ensure the pump receives clean, moisture free
air. Check and maintain the system's air lter on
a regular basis.
Although the air motor is coated with synthetic
grease upon factory assembly and can run
without lubricated air, Balcrank recommends an
in-line F.R.L. be installed in the pumping system.
Never let the pump run dry of the grease being
pumped.
Preventive Maintenance

Pump Operation
CAUTION: Read all limitations which apply
to selection of grease which may be pumped
by this product. Do not pump a grease which
is not specied to be compatible.
CAUTION: Always read and follow fluid
manufacturers' recommendations regarding
proper use of protective eye wear, clothing
and respirators.
To Start Pump:
1Immerse the pump's suction tube inlet into the grease to be pumped.
2Connect the air coupler to the pump and turn the air regulator to the minimum setting.
3Direct pump outlet hose into an approved waste oil container.
4Slowly adjust the air regulator until the pump is primed and running smoothly. Be sure all air has
been purged from the system. The pump should prime
in less than 30 seconds.
5Use the air regulator to control the pump's speed and cycle rate. Always use the lowest pressure
required to obtain the desired flow rate. This will
increase pump and seal life.
6Never allow a pump to be run dry of the grease being pumped. A dry pump quickly speeds up,
which could damage the air motor and uid seals. If
the pump suddenly speeds up, cut off the air supply as
soon as possible, rell the reservoir with grease and
reprime the pump.
7If the pump will be unattended for any period of time, or to shut off the system at the end of a work
shift, always follow the Pressure Relief Procedure on
page 2 of this manual.

Figure 5
4 If the Lower Body [4], Mufer [17], and Diffuser Plate [16] are attached to the Air Motor subassembly,
NOTE: The air motor is lubricated with a
life-tested synthetic grease (P/N 826733) at
the factory. This grease coats all parts and
repels air line moisture to inhibit corrosion. It
is imperative that any grease removed during
maintenance be replaced afterwards. Contact
your local Balcrank distributor, using the above
part number, for replacement grease.
Pressure Relief Procedure:
Follow this procedure whenever you shut
off the pump, when checking or servicing
any part of the system and when installing,
