5.3 Operating the Pump

With the pump set up, adjust all control settings for the pump motor and start pumping. Figure 5-5 shows fluid flow directions with respect to motor directions.

Extensive testing has shown that the minimum motor speed required to prime the tubing varies significantly with the size of the tubing. These variances are shown in Table 9-1 in Chapter 9. If the tubing will not prime regardless of motor speed, simply press on the stator (refer to Figure 5-3) while the stator is shut and the motor is running. Pressing on the stator enhances the priming action of the pump. Release the pressure after the tubing is primed.

NOTE

Make sure that the stator is fully latched before motor power is turned on. If the motor is turning, and the stator is unlatched for any reason, make sure to keep fingers and clothing away from the moving rotor assembly until the motor is turned off and the rotor assembly comes to a complete stop.
