Pump Repair/Servicing
Replacing the Pump Rod Seals:
Remove
foot valve (16) from fluid tube (13). Remove fluid
tube (13) from adapter (9) and slide off. With a
7/16" wrench, remove the 4 nuts (10). Slide the
adapter down about 2 inches and unhook the
rod (18) from the piston (37). Remove the fluid
rod (18) from the adapter (9). Now seals (8,
12,15, and 21) are accessible. Inspect balls (14
and 19) ; change as required. Reassemble in
reverse order. Apply grease (P/N 826733) to
seals (8 and 21) to ease assembly.
Footvalve:
With a pipe wrench, clamp to the
tube (13). Now remove foot valve (16). Remove
and inspect pin (17) for wear, straightness, etc.
Replace if required. Remove foot valve ball (14)
and seal (15), inspect, and replace if required.
Reassemble in reverse order.
CAUTION:
Before servicing, reduce
fluid pressure to zero. For safe
handling, use the recommended
Pressure Relief Procedure.
Pressure Relief Procedure:
To reduce the risk of serious bodily injury,
including fluid injection or splashing into the
eyes and/or onto the skin, follow the procedure
below before maintaining or repairing the pump,
the solenoid, or any part of the system.
1. Disconnect the air supply from the pump.
2. Open the dispensing valve into an
approved waste container to relieve pres-
sure on the system.
3. Leave any bleed-type drain valves open
until you are ready to use the system
again.
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.
It is
imperative
to maintain pump concentricity
when reassembling the Panther pump.
This can be achieved by reassembling the
pump ONLY in a vertical position; preferably
cap-down on a work bench.
