Pump Operation
Caution:
Always read and follow
fluid manufacturers’
recommendations regarding proper
use of protective eye wear, clothing
and respirators.
Caution:
Read all limitations
which apply to selection of fluids
which may be pumped by this
product. Do not pump a fluid which
is not specified to be compatible.
To Start Pump:
1.
Connect the pump’s fluid inlet to a fluid
supply.
2.
Connect the air coupler to the pump and
turn the air regulator to the minimum setting.
3.
Direct pump outlet hose into an approved
waste oil 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 1 to 2 minutes.
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 fluid being pumped. A dry pump quickly
speeds up, which could damage the air motor.
If the pump suddenly speeds up, cut off the
air supply as soon as possible and refill the
reservoir with fluid 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 page 2 of this manual.
Pump Repair/Servicing
Warning:
Before beginning pump
repair, all internal pressure must be
relieved. To reduce risk of personal
injury, follow the
Pressure Relief
Procedure
shown on page 2.
Model #1130-008 & 1130-023
Pump Disassembly / Reassembly:
Using a
soft jaw vise or a suitable fixture, clamp the
pump horizontally on the small diameter of the
housing (10). Refer to illustrations on pages 9
and 10 to aid in servicing the pump.
Removing the Air Motor:
Remove nut (3)
and u-washer (5) from cap (7). Remove cap
(7) from housing (10). Remove foot valve (24)
from pump tube (21). Remove pump tube
(21) from adapter (17) and slide off. Remove
six socket head cap screws (19) from housing
(10). Slide plate (18) off over rod (30). Grip
rod (30) on knurl, then use a spanner wrench
to remove fluid piston nut (32). Grip rod (30),
pull air motor assembly downward until the rod
can be slid out of the “saddle” stem (26) (See
graphic at bottom of page 6). Reach into the
top of the housing and remove the air motor.
The air motor and the housing o-ring (11)
can now be serviced. Reassemble in reverse
order,
being sure to use grease (Balcrank p/n
826733) on all seals and o-rings.
Replacing the Air Motor Seals:
Place air
motor on clean work surface with the air
valve mechanism up. Remove eight screws
(45), four posts (51) and the rest of tripping
assembly (48, 49, 50, and 52).
Take care not
to lose small parts.
Unscrew flange nuts (40)
and remove. Remove plastic washers (37) and
valve bar (42), replace plastic washers (37) as
needed. Replace o-rings (43) on valve stems
(39 and 46) as needed. To remove top spring
(35), remove plastic washer (54) and rod (36)
will slide out of valve bar (42). Snap lower
spring (35) off sleeve (55) and slide off rod (36).
Reassemble in reverse order,
being sure to use
grease (Balcrank p/n 826733) on all seals and
o-rings.
