GENERAL ASSEMBLY INSTRUCTIONS
Keep to recommended torque.
Grease thread lightly.
Do not use PTFE tape or hemp.
Components not supplied by us must be so dimensioned as to correspond to the given
dimensions of the diaphragm pump. - Note manufacturer's instructions.
Observe manufacturer's assembly instructions when using cutting rings or double conical
rings.
If liquids are to be pumped which contain chlorinated hydrocarbons (carbon hydrides), e.g.
trichloroethane or dichloromethane, the parts in contact with the material in the suction and
pressure system must not be made of aluminium or have a zinc-plated surface.
- there can be metal organic reactions which are explosive and extremely caustic.
COMMISSIONING
FLUSHING DIAPHRAGM PUMP
As every diaphragm pump is tested in the works after assembly using an anti-corrosion liquid it is
necessary to thoroughly flush out the rest of this liquid (and any other contaminants which have
entered during installation) with detergent (flushing agent).
- please see "Commissioning diaphragm pump/plant" ,
The detergent should be subsequently removed as completely as possible from the system. This
can be accomplished with air suction.
Set air inlet pressure < 0.5 bar.
Any detergent used must be compatible with materials to be used later; we recommend
consulting your material supplier.
COMMISSIONING DIAPHRAGM PUMP / PLANT
As the diaphragm pump works automatically with back pressure it can only be commissioned
(material transport) if material is extracted / let out of the pressure system.
Open compressed air supply to pressure control valve.
- Open stop cock in compressed air line.
stop cock handle parallel to compressed air pipe
