Changing Squeeze Tube

Squeeze Tube Replacement Procedures
REMOVING THE OLD SQUEEZE TUBE
1. If the chemicals you are pumping are hazardous in any way, you should wear safety
glasses and gloves when changing the squeeze tube. You should also have a rag handy.
2. Disconnect the inlet and outlet supply tubing from the squeeze tube by loosening the
compression nuts.
3. Remove the four (4) screws from the clear faceplate. Remove the faceplate. Make sure
that the faceplate bearing is either on the end of the motor shaft or in the center of the
faceplate.
4. Place a rag over both fittings in the bottom of the squeeze tube and pull the squeeze tube
towards you and work it out of the pump.
INSTALLING THE NEW SQUEEZE TUBE
1. Place the left side tube block in left hand block space – the head of the screw is facing out.
If the end of the screw is facing out, switch blocks so that the screw head is facing out.
Work the tubing into the pump from the 6:30 position clockwise around to the right hand
block.
2. You can turn the roller around in a clockwise direction and get the tube under it or you can
try to press the tube in between the roller and the side of the housing. This is the more
difficult of the two options.
3. Make sure that both, left and right, blocks are in place and seated in the recesses. Put the
faceplate back on the pump. Install the four (4) faceplate screws.
4. Reconnect and tighten the two (2) compression nuts. Make sure that the line from the
bucket is connected on the left and the one going to the machine or injection point is connected to the right.
