4.0 ™ Dual Channel Peristaltic Pump Head
The peristaltic pump head is specifically designed for use with the LabTec™ system.
The Parker pump heads (models 1082 & 1081) will provide you with rugged reliabili-
ty as long as
common sense maintenance and good quality pump tubing are used. For most dispens-
ing
applications, you should be using the 1082 (P/N: 080-1082) together with either #24 or #15(thick-
walled) silicone pump tubing.
For most dispensing application in the 10 mL to 500 mL range the 1082 (P/N: 080-1082) together with
thick-walled, #24 silicone tubing is the most appropriate and useful pump head / tubing combination.
Use #15 thick-walled silicone pump tubing for dispensing applications in the 2.5 to 10 mL range.
For dispensing applications below 2.5 mL, the 1081 (P/N: 080-108) together with thin-walled tube
sizes (#13, 14, 16) is the most appropriate pump head / tubing combination.
The pump head is typically driven by a 600 RPM, high-torque motor. The pump motor is
optically encoded and servo-controlled, thus the pump head will maintain a constant output over a
wide range of dispensing conditions.
However, when the pump head requires excessive torque because of pump tube failure or
“freezing” of the pump head, then the LabTec™ 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:
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
Parker to protect your pump motor and electronics.
CHECK PUMP HEAD
Press Any Key
Note: There is nothing wrong with the LabTec™ 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 return to the previous Menu. After you check and replaced your pump
head / tubing, you may re-initialize your application.
