5 Limitations for use in ATEX
Environment
(continued)
5.10 Lubricant Limitation
The following lubricants are approved for use on Verder
ATEX Dura pumps:
Verderlube blue
Verderlube clear
Danger of explosion due to incompatible liquids
Verderlube is glycerine based lubricant and therefore cannot be
used in applications that involve strong oxidizers.
u
It is incompatible with hydrogen peroxide, potassium
permanganate, nitric acid + sulfuric acid, perchloric acid
+ lead oxide, acetic anhydride, aniline + nitrobenzene,
Ca(OCl)2, CrO3, F2 + PbO, KMnO4, K2O2, AgClO4 and
NaH.
u
It reacts with acetic acid, potassium peroxide, sodium per
-
oxide, hydrochloric acid, (HClO4 + PbO) and Na2O2. Con
-
tact with potassium chlorate may be explosive.
Ensure Verderlube is not used as lubricant in applications that
involve the above chemicals to avoid accidental mixture with
pumped media in case of accidental hose burst.
The following lubricant
cannot
be used on ATEX
pumps:
Verdersil
6 Installation of Associated
Components
Before installing the pump, always check the identifica
-
tion plate of the pump.
The ATEX classification must correspond with the conditions
of the working environment.
6.1 Installing the Motor
1. Make sure the motor is suitable for use in a potentially
explosive environment.
2. Make sure that the motor is properly connected to the
power supply. Refer to the motor manual for the appropri-
ate instructions.
Earth connection
u
The power supply must include an earth connection.
6.2 Installing the Gearbox
1. Make sure the gearbox is suitable for use in a potentially
explosive environment.
2. Refer to the documentation of the gearbox for specific
product information about operating in a potentially explo
-
sive environment.
6.3 Hose Burst Detection Kit
It is essential to use ATEX rated hose burst detection sen-
sors to detect a potentially dangerous situation in time.
Use similar of higher ATEX rated devices with pump
u
Only use sensors that are approved by ATEX standards!
The classification should be similar or higher than that of
the pump.
6.4 Non-Standard Pump Orientations
There may be cases where the lubricant level cannot be
visually monitored through the inspection window such as
when the pump is fitted with metal inspection windows.
In these cases the customer should ensure that the pumps
are installed with appropriated ATEX rated hose burst de-
tection kit for additional protection (
g
refer to section 6.3).
6.5 Grounding the Pump
The pump should be grounded before operation. This can
be done either through motor earth wiring or alternately by
grounding through the base frame.
