Operation Without Fluid; Maximum Surface Temperature; Maximum Surface Temperature - Exothermic Reactions; Connection Pipes - WAGNER ZIP52 Finishing Operating Manual

VERSION 12 / 2012
OPERATING MANUAL
Cleaning
If there are deposits on the surfaces, the unit may form electrostatic charges. Flames or
sparks can form during discharge.
Remove deposits from the surfaces to maintain conductivity.
Use only a damp cloth to clean the unit.
4.3.2

OPERATION WITHOUT FLUID

Avoid running the pump sucking air, without fl uid inside. The air, combined with the
vapour of fl ammable fl uids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working regularly, paying special attention to the
presence of air in the pumped fl uid, which may be caused by a breakage in the pump.
Avoid operating the pump with damaged diaphragms.
4.3.3

MAXIMUM SURFACE TEMPERATURE

The maximum surface temperature of the pump depends on the temperature of the
pumped fl uid, that must not exceed the values indicated in the section "Technical Data".
4.3.4

MAXIMUM SURFACE TEMPERATURE - EXOTHERMIC REACTIONS

Fluids incompatible with the pump's materials or particularly reactive mixtures of products
with several components may cause exothermic reactions and develop dangerous
temperatures or pressure.
4.3.5

CONNECTION PIPES

Connection pipes must be made of conductive material and properly grounded.
4.3.6

PUMP PROTECTION

Pumping fl uids can contain solid particles, which could damage the internal parts of the
pump. The suction fi lter prevents solid bodies which are too large from entering the pump.
Refer to the paragraph Technical Data to verify the maximum size of solids that can be
pumped.
Keep metal surfaces clean. Electric conductivity of the surfaces is essential for explosion
protection.
Frequently clean the equipment so as to prevent insulating substance residue from
accumulating.
Do not use rusted parts or metal tools that may cause sparks of a mechanical origin inside
the explosion hazard area.
