compatibility.
WARNING
!
WARNING: The Panther®50:1
grease pump develops up to 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 determine 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
!
DANGER: Not for use with
fluids that have a flash point
below 100°F (38°C). Examples:
gasoline, alcohol. Sparking could
result in an explosion which could result in
death.
In the presence of explosive
vapors, take action to prevent
static sparking. Failure to
ground the pump, piping, valves, containers, or
other miscellaneous equipment can result in re or
explosion. A green grounding lug is provided on the
pump.
WARNING
!
WARNING
!
Use 3241-002 Pump Over-Run
control valve on pump air inlet for remotely

Product Description
The 50:1 ratio Panther®pump is suitable for grease distribution to multiple dispensing points or for
dispensing distances of up to 300 feet. Because of its superior ow rate and rugged design, it is ideal
for a wide variety of applications and installations.
The Panther's proven air motor features a precision air reversing 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) when the pump is caught between strokes.
The lower end is tted with Balcrank's exclusive, patent-pending intake system that dramatically
improves the pump's output by maintaining a high inlet vacuum. By creating such a high intake
vacuum, the chance of producing "voids" in the grease is practically eliminated.
It has a simple yet durable construction with all internal parts lubricated at the factory using a
life-tested synthetic grease (Balcrank P/N 826733). This grease coats all internal parts and repels
air line moisture to inhibit corrosion.
The Panther pump's exterior is constructed from aircraft grade extruded aluminum for an outstanding
strength-to weight ratio. The pump also has high quality Buna-N and urethane seals. It is a pump
that has proven to be reliable, yet easy to service and maintain.

CAUTION: Performance will be
affected by a suction path seal (follower
plate) that is not air tight.
To insure proper performance of your grease
pump, Balcrank recommends using a follower
plate if mounting the pump to a grease pail
or drum.
Refer to the following illustrations depicting a
typical drum-mounted installation.
Pump Installation
After removing the pump from its shipping
carton, attach to a suitable drum cover with the
mounting ring supplied with the pump.
STEP 1:
Using four 1/4-28 bolts and lock washers,
secure the pump to the drum cover.
STEP 2:
From underneath, tighten the holster.
STEP 3:
Slide the follower plate up the pump
tube as shown.
STEP 4:
Insert pump (with follower plate) into drum and
tighten thumb screws.
STEP 5:
Tighten one end of outlet hose to pump outlet.
STEP 6:
Secure control handle to the other end
of the outlet hose.
STEP 7:
Install a coupler or a ball valve into the pump's
air intake port. **Insure the valve is closed**
!

5
STEP 8:
Install a F-R-L onto the pump. Fill the lubrica-
tor with 10-20 wt. lubricant - set for 1 drop
every 2 hour.
STEP 9:
Connect compressed air to F-R-L.
STEP 10:
Set regulator to no more than 150 psi (10 bar)
STEP 12:
Open control handle into suitable
container to properly prime pump
and remove air from system.
Set-up complete (optional equipment shown)
25/35 LB. Installation:
Loosen set screw on mounting collar and
remove from pump. Install collar on cover and
complete step 1 and 2. Place cover on pail and
insert pump. Raise pump one inch from bottom
of pail and tighten set screw. Proceed with step
3 and rest of installation instructions.
Note: If your pail measures 16-1/2" or greater,
remove the mounting ring from the collar and attach
the mounting ring to the pump's outlet housing (item
19 on page 11 with the snap ring provided (item 26
on page 11).

CAUTION: Always read and follow
grease manufacturers' recommendations
regarding proper use of protective eye
wear, clothing and respirators.
CAUTION: Read all limitations which
apply to selection of greases which may
be pumped by this product. Do not pump
a grease which is not specied to be
compatible.
To Start Pump:
1. Immerse the pump's suction tube inlet into
the grease to be pumped (refer to "Pump
Installation" for more detail).
2. Connect the air coupler to the pump and
turn the air regulator to the minimum set-
ting.
3. Direct pump outlet hose into an approved
waste container.
4. Slowly 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.
5. Use 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.
6. Never 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 fluid 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 system.
7. Read and follow the instructions for each
component in your system.
8. If 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 pages 2 or
8 of this manual.
Pump Operation
The Panther®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 re-
quired to achieve the desired flow rate
(less than 125 psi and 150 cyc/min recom-
mended).
 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 syn-
thetic 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.
