DANGER: Not for use with uids
that have a ash point below 100°F
(38°C). Examples: gasoline, alcohol.
Sparking could result in an explosion which could result
in death.
WARNING
!
THIS PUMP CONTAINS
ALUMINUM AND ZINC PARTS. DO
NOT use 1-1-1 Trichloroethane, methylene chloride
or other halogenated hydrocarbon solvents or uids
containing such solvents in this pump. Use of these
solvents/uids may result in a violent chemical reaction,
causing serious bodily injury, property damage or
death. All uids used in this pump must be chemically
compatible with the wetted parts materials shown on
page three (3) of this manual. Consult your chemical
supplier to ensure compatibility.
Because this pump can be
incorporated into pressurized
systems, the following safety
precautions should be observed.
Check equipment regularly and repair or replace worn
and damaged parts.
Never alter or modify any parts of this pump, doing so
may cause damage to pump and/or personal injury.
Under no circumstances should the dispensing valve
be aimed at any person at any time. Personal injury
may result.
Release pressures built up in the system before any
service or repair is begun. See the pressure relief
procedure below.
Do not operate this pump above 150 PSI (10.3 BAR) air
inlet pressure or 300 cycles per minute.

recommendations regarding the use of protective
eyewear, clothing and respirators.
IMPORTANT
!
WARNING
!
Pump develops 195 PSI
(13.3 BAR) maximum working
pressure at 150 PSI (10.3 BAR)
maximum inlet air pressure. Be sure that any components
or accessories used in the system are rated to withstand
this pressure. To determine uid outlet pressure, multiply
the ratio of the pump by the air pressure being used.
EX: 1.3 (1.3:1 ratio) x 100 PSI = 130 PSI
uid pressure.
1.3 (1.3:1 ratio) x 6.8 BAR = 8.84 BAR
uid pressure.
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
!
If a check valve is installed at the end of the suction tube,
then an external pressure relief valve must be installed
at the outlet of the pump.

PRODUCT DESCRIPTION
The “Bobcat™ 130” pump family replaces the earlier “Trans-Jet
130”, “131A-CB & 131A-CBL”, “121”, “Econo-Jet” ™ (1.5:1)
and P-160/P-161 food pumps. These pumps are suitable for
petroleum products, chemicals, and USDA applications.
Four versions are currently available, two each in stub and
drum lengths. The 1110-005,1110-006 and 1110-008 are
composed of carbon steel parts with Buna-N seals for long
life. The model 1110-008 includes the model 4411-009 bung
adapter.
The 1160-002, 1160-003 and 1160-006 have all “wetted
parts” made from 304 SS or 316 SS and Viton and are USDA
approved. The model 1160-003 includes the model 4411-017
bung adapter.
All pumps contain a pair of 1 inch Delrin®balls which provide
compatibility for many uids and a smooth ow on both pump
strokes. For uids more viscous than 90W gear lube, carbon
steel or 300-series SS balls may be substituted.
All pumps are composed of a 2-piece body with the upper
section beingAluminum and the lower section beingAluminum
or 316 SS, depending on model number.
The lower section’s anged coupling contains a 4-hole bolt
pattern which allows 360° rotation of the inlet and outlet
ports in 90° degree increments. This feature is useful when
installing a pump on a wall bracket that limits orientation of
the hoses.
All pumps contain a pair of internal exhaust mufers which
provide efcient operation with low noise levels conforming
to OSHA regulations. These mufers also act as lters,
inhibiting air line debris from exiting the pump where cleaner
environments are required.
The 1-piece pump air motor is factory-lubricated with a life-
tested, synthetic grease (Balcrank #826733). This grease
coats all internal parts and repels air line moisture to inhibit
corrosion. Steel components exposed to air line moisture are
surface treated to inhibit corrosion.

TYPICAL INSTALLATIONS
INSTALLATION
Remove pump from carton and attach to cover, bung tting
or other mountings.
Blow out any foreign material from the air supply line before
connecting to pump. An air line lter/regulator is recommended
for all applications; wet and dirty air will shorten the life of the
pump.
NOTE: For severe duty applications, an air line lubricator
is recommended for better performance and longer pump
life. Use an SAE 10 oil and set the lubricator for 2 drops per
hour.
Be sure the air supply is OFF before connecting accessories
and/or pump.
NOTE: DO NOT hang Filters/Regulators/Lubricators or other
equipment of this type directly from pump air inlet. The ttings
are not strong enough to support the weight and may cause
one or more to leak and/or break. A bracket should be used
to support the use of these products.
1. Install an air line regulator to control pump speed and air
pressure for the system.
2. Install an air line lter to remove and trap contaminates
that could cause unwanted wear and tear on pump air
motor.
3. Install a quick disconnect coupler to relieve air pressure
between the pump air motor and regulator for servicing
purposes later.
4. Install uid hose, making note of uid and pressure
compatibility of hose.

CAUTION
If you are not using a low-level cut-off at the pump uid
intake, install a pump runaway valve to shut off the air
to the pump, when the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can be
seriously damaged.
!
WARNING: Attach a proper ground wire to the
Bobcat’s grounding lug (item 40) before starting
the pump.

OPERATION
NOTE: All uids used in this pump must be chemically
compatible with the materials used to manufacture the
“wetted parts”. Consult your chemical supplier to ensure
compatibility.
TO START PUMP:
1. Connect air coupler to pump and turn the air regulator to
the minimum setting.
2. Direct outlet hose into an approved waste oil container.
3. Slowly adjust air regulator until pump is primed and is
running smoothly. Be sure all air has been purged from
system. The pump should only take a few strokes to
prime. However, in a large system, it may take longer.
4. Use the air regulator to control the pump speed and cycle
rate. Always use the lowest pressure needed to obtain
the desired ow rate. This will increase pump and seal
life!
5. Never allow a pump to run dry of the uid being pumped.
A dry pump quickly speeds up and can damage the air
motor. If it speeds up, shut off air supply immediately. Rell
the supply container and prime the pump to eliminate air
in the uid line.
NOTE: To prevent air from being sucked into the pump and
uid lines, if the supply container should run dry, use a low-
level cutoff valve (4411-010) at the pump uid intake.
6. Read and follow the instructions supplied with each
component in your system.
7. If the pump will be unattended for any period of time, or
to shut off the system at the end of the work shift, always
follow the Pressure Relief Procedure.

PUMP SERVICING
NOTE: Air motor is lubricated with a life tested synthetic
grease (Balcrank®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 routine
maintenance be replaced. Contact your local Balcrank®
Distributor, using the above part number, for replacement
grease.
NOTE: The following steps and item numbers pertain to the
stub pumps. Except for a few uid section components (pump
tube, pump rod, uid piston, etc.), stub and drum pumps are
alike. When repairing a drum pump, pay close attention to
different parts that may carry the same item number as their
stub counterparts, such as the pump tube (35).

washers (32) and separating the upper (25) and lower (31)
body sections. Use snap ring pliers to remove the retaining
ring (28). Remove the backup ring (29) and seal (30). Apply
Balcrank lubricating grease (p/n 826733) to the seal area and
install a new seal ared side down. Work carefully to avoid
seal tearing around the snap ring groove. Reassemble in
reverse order.
Lower Spring and Air Motor Replacement: Replace the
spring (23) by sliding off the old spring and sliding on the
new part. The air motor (1 ) is a 1 -piece, staked assembly
that cannot be disassembled for repair of internal o-rings
or upper seal. Replace the entire assembly using Balcrank
Repair Kit 827711.

Wrap the upper pump rod (2) with protective material or use
wood/plastic blocks to grip it in a vise. Use a wrench to remove
the air motor assembly at the hex adaptor (1) pump rod (2)
joint. Note: If the upper pump rod needs replacement, do so
before the new air motor is installed (refer to Replacing the
Upper Pump Rod). Apply thread adhesive to the air motor
before installation.
Upper Spring and Flat Seal Replacement:
Unscrew cap (17) from air piston tube (22). Remove screw
(21), spring retainer (20) and spring (19) and lift out upper
gasket (18). Reassemble in reverse order.
Replace the lower gasket (18) while the tube is off the body
(25). Be sure the new gasket is at against the body before
assembling the tube
Replacing Parts in the Footvalve: Grip pump tube (35)
and footvalve (37) with separate strap wrenches. Unscrew
the footvalve, drive out retainer pin (38) with a 1/8” diameter
punch, remove lower ball (14) and/or o-ring (36) as necessary.
When reassembling the pump tube to the lower pump body, be
sure to check the upper o-ring (34) for damage and replace as
necessary. Apply grease to the footvalve threads and o-rings
(34,36) and reassemble.
Replacing the Upper Pump Rod: Grip only the upper rod in
a vise. Use a 1/8” spanner wrench to remove the oating joint
adapter (5) and air motor assembly (1) from the upper rod.
Wrap the replacement upper rod in protective material before
placing in the vise. Apply thread adhesive to both internal
threads of the pump rod and reassemble the connecting
parts.
Replacing the Lower Pump Rod: Grip only the lower rod
in a vise. Use a 1/8” spanner wrench to remove the oating
joint adapter (5) from the upper rod (2). Wrap the upper rod
and air motor assembly and set aside.
Use an adjustable wrench to remove lock nut (3). Slide off
washer (4) and adapter (5). Remove connecting rod (6) with
a pipe wrench. Wrap replacement lower rod in protective
material before placing in the vise. Apply thread adhesive to
the connecting rod (6) and reassemble with the short thread
length into the rod. Replace the washer (4), adapter (5) and
nut (3). Tighten nut completely then back off 1/4-tum to allow
free movement of adapter. Apply thread adhesive to the
adapter and reassemble.
Pump Reassembly: Apply grease to the lower pump rod end,
wiper seal (30) and o-ring (24). Slide the lower spring (23) over
the upper pump rod and then slide the entire upper rod/lower
rod/air motor assembly through the pump. Some resistance
will be encountered as the lower rod passes through the wiper
seal (30). Reinstall the upper ball (14) and piston (15). Insert
a 1/4” diameter rod through the pump rod and tighten the
uid piston with a wrench. File off any burrs or raised areas
created during the repair process.
Grease o-rings (16,34) and pump tube (35) threads before
reassembling to the body. Tighten with a strap wrench.
Grease the air motor assembly and inside the tube (22),
reassemble and tighten with a strap wrench.

Balcrank Lubrication Equipment Warranty Statement
All Balcrank equipment sold by authorized Balcrank distributors is warranted to their original customer to be free from defects in materi-
als and workmanship for a period of one year from the date of sale to that customer. Selected Balcrank equipment carries warranty terms
for a more extended period as dened in the Balcrank Lubrication Equipment & Accessories User Price List, wherein a “lifetime” warranty
represents a warranty period of thirty years. Within the initial one-year warranty period, Balcrank will repair or replace all Balcrank equip-
ment determined by Balcrank to have defective materials or workmanship. For equipment carrying more extended warranties, Balcrank
will repair or replace the product including parts and labor during the rst full year and will provide parts only for the remainder of the war-
ranty period.
This warranty applies only to equipment installed and operated according to applicable Balcrank Service Bulletins and Installation Instruc-
tions.
Any equipment claimed to be defective must be returned, freight prepaid, to an Authorized Balcrank Service Center (ASC). Upon receiv-
ing candidate warranty equipment from a customer, ASC will: 1) diagnose to determine the warrantable condition of the equipment, 2)
submit, prior to repair or replacement, a request to Balcrank for warranty authorization, then 3) in cooperation with Balcrank, proceed with
repair locally or forward the equipment to Balcrank and obtain replacement. If the part(s) or equipment items are found defective upon
inspection by Balcrank, they will be repaired or replaced, and then will be returned to the ASC. If Balcrank nds the claimed part(s) or
equipment not to be defective, the ASC will receive written authorization from the original customer, and then repair them for a reasonable
charge to the customer, which will include all applicable parts, labor, and return transportation costs.
Optionally, the customer may submit certain eligible products directly to Balcrank for warranty return by using Balcrank Lubrication Equip-
ment Direct Service Warranty Procedure. Eligible products are dened in the Balcrank Lubrication Equipment & Accessories User Price

Any equipment returned to Balcrank must have the Warranty Service Claim number (WSC#) clearly marked on the outside of the carton.
Balcrank’s sole responsibility is for defects in material and workmanship, and Buyer’s sole and exclusive remedy hereunder, shall be
limited to repair or replacement of the defective part or equipment.
This warranty does not cover, nor shall Balcrank be liable for repair or replacement of parts or equipment resulting from general wear and
tear through use, or damage or failure caused by improper installation, abuse, misapplication, abrasion, corrosion, insufcient or improper
maintenance, negligence, accident, alteration, or substitution of non-Balcrank parts.
Furthermore, the Warranty for Lubrication Equipment and Accessories does not cover the following specic conditions:
