5.3.12 Pumps

If any of the pumps are not pumping (liquid flow is not observed moving up the tubing), check to see if the motor is turning the pump heads and the motor is not binding. Check for proper power and connections to the pump motor. If the motor has failed (e.g., open windings, etc.), replace motor. For 110 V 2 RPM motor , use P/N ST18002; for 220 V 2 RPM motor use P/N ST18003. For pump motor replacement, refer to Section 5.3.12.1 and Figure 5-14.

If the motor is operating properly, worn tubing is the probable cause for poor or non–existent pumping. Retube pump heads as described in Section 5.3.12.2 and Figure 5-15.

5.3.12.1PUMP MOTOR REPLACEMENT

Note: Masterflex pump heads must be removed for access to Pump Motor Mounting Screws.

1. Turn main power OFF.

2. Remove 4 wing nuts from pump head mounting hardware.
