Flow rates
Flow rates for the 605Di/R &605Di/L were obtained pumping water at 20C with negligible suction and delivery pressures (unless
otherwise stated). Where an application is critical, the flow rate should be determined under operating conditions. The important
factors are suction and delivery pressures, temperature and fluid viscosity.
603R pumphead
The 603R has two spring loaded rollers, which automatically compensate for minor variations in tubing wall thickness, giving
extended tube life.
The 603R is set during manufacture to accept a nominal tubing wall thickness of 3.2mm and bore sizes of between 4.8mm and
15.9mm.
The pumphead can be run clockwise for extended tube life or anti-clockwise to operate against higher pressures.
603R/605L guard wiring
Remove the top half casing from the drive. Pass the switched guard wires through the front panel of the drive and connect to the
terminal blocks as shown below. Replace horizontal, front and back panel case gaskets to ensure the IP55 ingress protection
standard is not compromised. Replace top half casing.

Fit the track over the drive shaft and locating boss. Secure the track with the retaining screws. Ensure the drive shaft has been
completely degreased before locating the rotor onto the shaft via a split collet. Tighten the rotor bolt to a torque of 13Nm to prevent
the collet slipping during operation.
• Pump shown in track loading pictures is the 603S/R
To remove the track, remove any tubing from the pumphead. Loosen the rotor securing bolt and give the rotor/bolt a sharp tap to
free the collet. Release the collet, and withdraw the rotor from the shaft. Loosen the two track securing screws and pull the
