Possible Solution
When “Check Pump Head”
error occurs with your
peristaltic head.
Does “Check Pump Head”
occur with no tubing in the
head?
If it occurs with no tubing in the
head, call Parker. You may
need a new motor.
Confirm the tubing sizes
you are using.
If no, make sure you are using
the correct size tubing. Thick
walled tubing in a thin wall
pump head will cause this, and
may break the head
When peristaltic pump
head turns, but no fluid
flows.
Check the tubing size and
pump head type, as you
may be using the wrong
size for that head.
Tandem 1081 is for thin-walled
tubing, and 1082 is for thick-
walled tubing. Thin-walled
tubing in a thick walled head
won’t produce much flow. Use
the correct size tubing.
Tubing Size is ok
The pump head may be
cracked from being forced
closed with the tubing
crosswise or the wrong size
tubing. Contact Parker for repair
or replacement parts.
When the pump head turns
ok with no tubing installed,
won’t turn when you put
tubing in, and you don’t get
a “Check Pump Head”
error.
The coupler is loose or
broken.
