Changing of the tube without disassembly of rotor
WARNING!
Read the material safety data sheet (MSDS) of the process fluid and obey the described
safety measures!
IMPORTANT!
Use original Lutz-Jesco pump tube only! The use of different tubes may damage the
drive.
Never grease the tube!
CAUTION!
Before changing the tube always ensure, that the tubes don’t contain residue of the
process fluid: Acids and lyes may cause dangerous injuries to your eyes and to your
skin. Wear safety equipment (i.e. goggles, gloves, apron, etc.). If necessary, protect
the environment from escaping chemical/process fluid.
WARNING!
The turning rotor can cause harmful contusions!
Ensure, that the pump is always disconnected from the power supply, while exchanging
the tube
(switch off power supply of the chemical feed system!)
The pump housing is a wearing part and must be changed after reasonable periods of
time according to the following description:
Take off front cover (12) as shown in AIII. Remove cover of pump housing and rotor
cap. Pull out tube retainer with old pump tube while turning the rotor by hand. If the
pump housing is wet or dirty, due to escaping process fluid, the rotor must be dismantled
and the inside of the pump housing must be cleaned and dried carefully. Remove old
pump tube from tube retainer and install a new tube without twisting it. Use the tube
fixings. Insert tube retainer with new tube into pump housing. Insert tube into the track
inside pump housing by turning the rotor by hand. Fasten cover of pump housing.
