TUBING INSTALLATION/PUMP HEAD ASSEMBLY
Inspect all tubing regularly and replace if any sign of deterioration
occurs. Always wear safety glasses and protective clothing when
working with chemicals. (See Illustrations on page 5)
1 . Disconnect power to the pump.
2. Disconnect the suction and discharge tubing from the pump tubing.
(if the product pumped is not caustic, tubing may be removed by
running pump and pulling on the discharge tube until tubing is
removed. In this case skip steps 4-5)
3. Remove (2) screws (E) to release pump head assembly.
4. Remove tube housing (D) by gently rocking side to side while
pulling off. (in most cases roller bracket should stay on shaft. In the
event that it is removed with the housing, line up flat on shaft with
flat on inside of bracket and push back into place. There is also a
tubing cover ring (A) that should be on up against the motor case.
This is free floating until the tube housing is replaced.)
5. Remove tubing from roller bracket.
6. Clean roller race inside of tube housing, removing any particles that
could damage tubing. Be sure all cleaning solvents are removed prior
to installing new tube.
7. To reassemble, rotate roller bracket assembly so that the rollers are in
the 10:00, 2:00 and 6:00 positions (See Illustration I -I). Lay the tube
over the top rollers and hold the ends together at the 6:00 position.
Put the tube housing (with tube inlet and outlet restraints down)
over the roller assembly and the tube, locating the ends of the tubing
into the tube inlet and outlet restraints.
8. Press tube housing onto shaft while gently pulling down to align
shaft into tube housing bearing. Press tube housing flush to motor
case and replace screws.
Be sure not to twist or leave the tubing pinched while
installing, as this will affect your flow and tubing life.
