In addition, pumps were designed and made in accordance with these standards:
UNI EN 809: 2009 – Pumps and liquid pumping units – General safety requirements.
UNI EN ISO 12100-1: 2005 – Machine safety. Basic principles, general design
principles. Part 1: Basic terminology, methodology.
UNI EN ISO 12100-2: 2005 – Machine safety. Basic principles, general design
principles. Part 2: technical principles.
CEI EN 60204-1: 2005 – Machine safety. Electric wiring. General rules.
1.4 Fields of application
Progressing cavity pumps are used to pump fluid as requested in the order concerned.
Any pump must not be used for fluid whose chemical and physical properties differ from
the ones set out in the order.
The max. pressure required must be lower than the max. pressure a pump can reach,
adequately reduced to take into account any leakage from delivery piping.
Unless otherwise stated, the pump must not be used in places where potentially-
explosive atmospheres may occur.
1.5 Noise
The average noise level A emitted by the pump must not be higher than 80dB(A).
1.6 Safety warning
1.6.1 Overpressure
The progressing cavity pump must be installed within a plant. The delivery pressure of
these pumps is only limited by the power of machines.
DANGER!
In case delivery of pump is intercepted, pressure rises until piping breaks or the pump is
damaged, which may cause leakage of fluid under pressure.
The plant must therefore be equipped with proper safety devices such as manostats
and fracture disks with return piping as shown in § 4.6.
