Problem
No flow out of the outlet tubing
Solution
1. Check to see that the Stator is
snapped shut. If it is, push down on
the Stator while the motor is
running. This action enhances the
self-priming capability of the pump.
2. Make sure the tubing is loaded
properly. The tubing should be
centered in the middle of the
rollers. Reload if necessary.
3. Check to see that the tubing has no
holes or cracks. Replace with new
tubing, if necessary.
4. Check that the inlet tubing is fully
immersed in fluid.
5. Check that the motor is rotating in
the correct direction. Refer to Figure
5-5.
6. Check to see if the tubing is
clogged. Replace with new tubing,
if necessary.
7. Check to see if the pump is properly
mounted to the motor. Refer to
Section 3 for instructions on proper
mounting.
8. Check to see if the Rotor Assembly
is worn or stuck. Check that the
rollers spin freely. Use a high
pressure air hose to blow out
particles from the pump which may
be restricting roller motion.
