PUMP SQUEEZE TUBE LUBRICATION
The peristaltic pump squeeze tube should be
lubricated at least once per year, or when the pH
BOSS displays the lubrication reminder message.
You do not need to remove the inlet and outlet hoses
to lubricate the pump squeeze tube.
PUMP SQUEEZE TUBE REPLACEMENT
If the peristaltic pump squeeze tube breaks or loses
its flexibility for pumping, it needs to be replaced.
Remove the old tube and fit a new tube as per the
lubrication procedure on this page. A replacement
Squeeze Tube can be ordered by telephone or online
at www.phboss.com or www.bionizer.com.au.

cover.
Remove the Squeeze
tube. The pump rotor
may come out too, but
can easily be pushed
back into place.
Pull out the pump rotor a little, and place the
squeeze tube between the pump body and the two
rollers.
Push the squeeze tube and rotor into the pump
body. Ensure that the inlet and outlet are seated in
the guides on each side of the pump body.

cover.
Lift up the pump cover
from the bottom side.
Apply a
THIN SMEAR
of Silicon grease to the
squeeze tube and pump rotor shaft as shown
above.
Apply Silicon
grease here.
DO NOT
over-lubricate, as this will attract dirt and
grit, which will cause premature wear of the
squeeze tube and rollers.
WARNING : Use only silicon grease. Petroleum gel
and other oil-based lubricants may cause the
squeeze tube to break down, resulting in corrosive
diluted acid spillage.
Re-fit the pump cover until it clips into place. There
should be no gaps anywhere between the pump
body and cover.
Ensure that the squeeze tube is not pinched on
either side, after the cover is replaced.
