PureTec

6.0 TANDEM Dual Channel Pump Head:
The TANDEM peristaltic pump head is specifically designed for use with the
PureTec system. The SciLog TANDEM pump head will provide you with rugged
reliability as long as common sense maintenance and good quality pump tubing are
used. For filtration applications, you should be using either Platinum-Cured Silicone
or PharMed pump tubing in the correct sizes.
The TANDEM pump head is driven by an 8, 160, or 600-RPM, high-torque motor.
The pump motor is optically encoded and servo-controlled, thus the TANDEM pump
head will maintain a constant output over a wide range of filtration conditions.
However, when the pump head requires excessive torque because of pump tube
failure or “freezing” of the pump head, then the PureTec control software will
recognize this condition and go into a stand-by mode, the pump motor is turned off
and the following message is displayed:
CHECK PUMP HEAD
Press Any Key
Before continuing with your pumping application, remove the defective pump head /
tubing and either clean or replace with a functional pump head. This feature
(PumpSense) has been implemented by SciLog to protect your pump motor and
electronics. NOTE: There is nothing wrong with the PureTec controller when
you see this display. The problem lies with the pump head and /or pump
tubing you are using.
When you “Press Any Key” to leave the stand-by mode, you will enter the Main
Menu. After you check and replaced your pump head / tubing, you may re-initialize
your application.
