Part 3: 603R pumphead
Tube loading
Switch off the pump and isolate it from the mains supply before loading
tubing. If the pump is not switched off before the pumphead guard is
raised, a switch on the guard will cut off power to the motor. This
switched guard is a safety back-up system and must not be used as the
primary on/off switch for the pump.
The 603S/R is fitted with a spring loaded twin roller pumphead designed for
tubing with a nominal wall thickness of 3.2mm (1/8") and bore sizes of
between 4.8mm (3/16") and 15.9mm (5/8"). A length of 410mm (16") of tubing
is needed for the pumphead.
Open the pumphead guard and fit one end of the tube into the bottom
adjustable clamp. Tighten the lower knurled adjustment wheel. Then, whilst
rotating the rotor clockwise (a spanner is provided for this purpose), feed the
tube between the rollers and the track, ensuring that the tubing is not twisted
or stretched. This is particularly important for the larger bore sizes of tubing.
Fit the other end of the tube into the top adjustable clamp, ensuring that the
tube is not slack in the pumphead. Clamp the tube very firmly by turning the
upper knurled adjustment wheel. Remove the spanner and close the guard.
Tubing range
Pump performance depends upon the accuracy and consistency of the
tubing. All Watson-Marlow tubing is specifically formulated for peristaltic
pumping, and is manufactured and quality controlled to our own
specifications. We recommend Marprene tubing whenever it is chemically
suitable. The Product Codes for each of the available tubing types are listed
below.
