501RL pumphead
The 501RL pumphead has two spring-loaded working rollers, which automatically compensate for minor variations in tubing wall thickness,
giving extended tube life. The 501RL is set during manufacture to accept tubing with wall thicknesses of between 1.6mm and 2.0mm, and
internal diameters of up to 8.0mm. It is equipped with a “tool lockable” guard for increased safety. This should be locked shut whilst the pump
is in use.
The pumphead can be run clockwise for extended tube life, or anti-clockwise to operate against higher pressures.
Flow rates
Flow rates for the 504Du/RL were obtained using silicone tubing with the pumphead rotating clockwise, pumping water at 20C with zero
suction and delivery pressures. For critical applications determine flow rates under operating conditions.
501RL installation
Fit the track in any one of three orientations, over the drive shaft and locating boss. Secure the track with the locating screw. Ensure the drive
shaft is degreased before locating the rotor onto the shaft via the split collet. Tighten the rotor screw to a torque of 3Nm to prevent the collet
slipping during operation.
To reposition the track, swing out the crank handle to expose the rotor retaining screw. Turn the screw anticlockwise one turn to release the
collet, and withdraw the rotor from the shaft. Loosen the track locating screw, and pull the track clear. Rotate the track to its new position and
tighten the track locating screw. Use this method of removal and fitting in case cleaning is required.
