2.2
Ambient conditions
The Hawk pumps described in this manual have been designed and manufactured to operate in potentially explosive atmospheres.
The working parameters are specified in the ID plate (see fac-simile in sect. 3.8).
Below is a short list of these parameters.
Parameter
Admitted values
Ambient temperature
-10°C to +50°C
Storage temperature
0°C to +50°C
Humidity
20% to 80%
Max. pumped fluid temperature
+65°C
2.3
Vibration
In normal operating conditions, if the installation and assembly procedures described in this document have been followed
correctly, Hawk pumps do not generate vibration such as to pose the related risks. Additionally, no contact with the operator is
envisaged as the pumps are incorporated in an end machine/system.
2.4
Noise emissions
The equipment has been designed and manufactured so as to reduce the level of noise emissions at source, compatibly with its
intended use and operating principle.
The measured noise level is below the min. level prescribed by the existing regulations.
2.5
High temperatures
Mechanical parts are lubricated to prevent overheating due to prolonged friction over time. The lubrication oil, which is specified
later on in this manual, was selected according to its compliance with the ATEX classification of the pumps. Moreover, overheating
does not represent a risk in terms of probability if normal maintenance procedures are implemented.
Wear suitable personal protective equipment, such as gloves and work clothes, as supplied to the operators.
2.6
Stability
Pumps from the series KR-KR ES ATEX are supplied with the necessary instructions for their stable and safe installation in the
machine/system where they are incorporated. The assembler/user shall thoroughly follow and comply with these instructions.
The pumps have been designed and manufactured so that they do not pose any risk in terms of stability when operated normally.
2.7
Fluids under pressure
The pumps described in this manual are manufactured with suitable materials to resist the required working pressures.
Additionally, all components (plugs, valves, pistons, etc.) required for correct operation and fluid recycling have been fitted (see
table in Chapter 2 and lubricant oil table). The transmission lubricant products used in the pump body serve the purpose of keeping
the mechanical components lubricated, thus ensuring correct pump operation.
Le pompe Hawk, oggetto di questo manuale, NON sono state progettate e costruite per lavorare in
presenza di un’atmosfera potenzialmente esplosiva.
Per tale tipologia di Pompe consultare il catalogo del Costruttore o contattarlo.
Additional information is provided in Chapter 5 “Installation”.
