Product Description The D-500 Disperser is a high speed dispersing instrument. It is based on the Rotor/Stator Technology. The shaft and rotor/stator can be disassembled for easy cleaning. You will receive the dispersing tools completely assembled for immediate use with your disperser. Should you dismantle these (e.g. for cleaning) please refer to page 6.
• It is recommended that the operator should be using hearing protection when operating the unit at maximum speed. • Do not operate after the equipment malfunctions or has been damaged in any manner. Return unit to our service center for examination and repair. • • • Switch off the unit before changing the dispersing element. Only suitable dispersing shafts from SCILOGEX may be used. Glass vessels must always be secured with a clamp to prevent them from sliding.
Proper Use The voltage on the name plate must match the main voltage. If it does not, do not operate the instrument. Screw the support rod into the flange of the drive and tighten it. Make sure that the “nylon” washer is between the flange and the nut to avoid scratching and rubbing marks on the flange. Make sure that the unit is switched off when connecting or disconnecting the dispersing shaft into the drive. For correct use the D-500 drive must be secured to a stand with a boss head.
Dispersing Aggregates • Disassembly of the dispersing tool 1. Hold the dispersing tool with a cloth (to avoid cutting of your hand due to sharp edges at the stator). At the same time turn the shaft tube clockwise. Screw the shaft tube of the stator and pull it over the axle and put it aside. 2. Now hold the rotor with a cloth and turn the axle anticlockwise. Slowly screw the axle from the rotor and put it aside.
3. Remove the PTFE bearing from the axle. After this disassembly you should have the following five parts: shaft tube, axle, rotor, stator and PTFE bearing. To assemble the dispersing tool please follow above 3 steps in reverse order (3./2./1.) When assembling the dispersing tool, always make sure that the PTFE bearing is fixed correctly and cooled by the working medium. Otherwise, it may cause serious defects to the whole dispersing tool. Examine the PTFE bearings regularly.
Working with D-500 The optimal immersion depth of the dispersing shaft is approximately 2/3 below the liquid surface and 1/3 above the bottom of the beaker. When inserting the dispersing shaft slightly slanted (approximately at an angle 15 degrees), it improves the efficiency of the disperser. The dispersing shaft should not be immersed more than 30mm below the flange. Working with Speed Control The drive and control are in the same housing.
Overload Protection When the motor overloads and the power supply cuts off, switch off the main switch to O, disconnect the aggregate and re-start the instrument as fast as possible, without the load in order to accelerate cooling by the built-in fan. Maintenance of Motor The motor does not need any maintenance and there are no parts inside which can be repaired by the user. The only parts which are excluded from this are the carbon brushes.
Once this bottom “H” has been fixed, take the double rod and insert into the middle piece of the foot stand. Turn it around and fix it with the other allen key using the smaller screws for it. Turn it around and fix the drive with the support rod at the upper boss head and the strap clamp at the lower boss head. Assembly of the PT plate stand This stand is delivered with a base plate and a rod which is either 600mm, 800mm or 1000mm long.
