During operation the handle of the pump must be pushed-in. In order
to avoid an electrostatic charge at the handle of the pump and other
surfaces made from plastic, it should only be cleaned using a moist
piece of cloth.
7
Dust layers must be avoided to prevent a hazardous warming up of
the pump‘s surfaces.
Classification and Marking of the Pump
The TRIVAC D16 B Ex is assigned to different equipment-categories regard-
ing the pump’s outside and the process gas side’s interior parts.
The process gas side of the pump was specifically designed and constructed
to comply with the safety requirements of equipment-group II, category 1
IAW Directive 2014/34/EC (“ATEX Guidelines”) on the conforming utilization of
equipment and protection facilities in explosion hazardous areas.
The pump’s outside fulfills the requirements of equipment-group II,
category 2.
The utilization of the pump must be verified by the operating company
against corresponding equipment-categories, temperature classifications and
gas groups as specified in the explosion protection document drawn up.
Pumps where the inside and the outside of the pump fulfil the basic safety
requirements of the Directive, are supplied with an ATEX certified motor and
have been marked as follows:
P/N 140 091
II (inside) 1G IIB3 T4 X (50 Hz)
II (outside) 2G IIB T4 X (50 Hz) (12 °C < Ta < 40 °C)

General Explanation of the Symbols
II
Equipment-group II applies to all equipment for use in areas which can be
endangered by an explosive atmosphere except in underground mining
operations and their related above ground systems which can be endan-
gered by mine gas and/or combustible dust.
(inside) / (outside)
Specifies the category/conditions according to which
the inside (i.e. sections of the equipment in contact with the process gas
flow) and the outside of the equipment are classified provided these differ.
1
Equipment-category 1 applies to all devices for use in areas in which
explosive atmospheres caused by mixtures of air and gases, vapours,
mists or air/dusts mixtures are
highly likely
to occur and are present
continuously, for long periods of time or frequently.
