PERISTALTIC PUMP HEAD AND MOTOR
The pump stand utilizes a variable speed pump motor and special norprene pump
tubing for liquid metering. Each pump comes equipped with 1 peristaltic pump head.
Liquid will only come into contact with the inside diameter of the pump tubing and not
the pump. This allows for easy cleanup and less maintenance of the pump.
To open the pump head, rotate the lever to the left. Place the pump tubing inside the
pump head so it fits inside the notches and above the rollers (bottom, left). Rotate the
lever back to the right and close the pump head, clamping the hose inside the head
(bottom, right). Wear or fatiguing of the tubing within the pump head due to
compression is normal. When tubing becomes worn or chemical rates begin to slow
down, open the pump head and move the tubing to a different position. If the entire
piece of tubing becomes worn, simply replace with a new section. When not using the
pump stand for several days or when storing, open the pump head and remove the
tubing to prevent any extra compression.
