BOD-300 Peristaltic Pump 

9 .1 PERISTAlTIC PUMP REPlACEMENT

Empty line from liquid on the pump that needs to be serviced. 

Disconnect inlet and outlet tubing. 

Remove 2 screws that hold the peristaltic pump. 

Replace tube that is inside of the plastic cover. 

Install the 2 screws that holds the peristaltic pump.

Installation is reverse of removal. 

After installing pump, open the software and verify if the pump is working properly. 

Figure 36. Peristaltic Pump.

 After servicing peristaltic pump(s), flow rate calibration need to be performed in software for proper accuracy.
