General Maintenance for CC-2B Series Pumps
Maintenance
The pump is equipped with a Gits-type oiler which permits the occa-
sional lubrication of the Flex-I-Liner interior with Vanton Pump oil or pure
Silicone oil of 2000 centistokes viscosity. If the pump is used in continuous
service, add a small amount of this oil each week (about 7 drops); less
often for less severe service. This servicing is accomplished by stopping
the pump, raising the spring-loaded cover of the Gits oiler and adding the
oil.
CAUTION: Organic oil must not be used. The only recommended oil for the
specified above is Vanton Pump oil or pure Silicone oil.
The Vanton Pump employs ball bearings which have been packed
with grease at the factory and require no further lubrication.
Repair
Usually the repair of the Vanton CC-B Pump is an extremely simple
procedure. After long or severe service, the Flex-I-Liner (item 4) may
become worn or break. Replacement of this part restores the pump to its
original performance. The steps for doing this are as follows:
Note: Refer to Figure A-3 for part item numbers.
(1) Obtain the following items:
• 1 /
2
" open-end wrench, or box wrench, or socket ratchet
• Replacement Flex-I-Liner and Vanton oil
(2) Remove four bolts (14) using the 1 /
2
" wrench or socket.
(3) Remove cover plate (1).
(4) Remove expansion ring from the now exposed Flex-I-Liner (17).
(5) Grasp the body block (2) and pull it away from the bracket (30).
(6) Remove the worn Flex-I-Liner from within the body block.
