3.6 Risidual risks

Danger due to moving

mechanical components

Hazard oIgetting caught and drawn into machine pinch points by loose clothing that

become entangled. Pinch points are represented by all rotating or reYolYing parts

and by power transmission apparatus. )ollow lockout procedure beIore serYicing. Do

not operate without proper protectiYe guards. Stay clear oIthe machine area while

chine.We recommend to mount a disconnecting switch upstream in order to insulate

the power supplyto ensure saIety maintenance operations

Danger due to thermal

hazard

Thermal hazards on this type oImachine are concentrated determinated areas. While

6.2 Installation

The machines described in this manual can be driYen by electric motor or thermic engine through elastic coupling. When the pumps are coupled

with electric motorthe motor is in compliance with ³I(C 34-7I(C 72”- standards.

to ensure the correct engine cooling.

In order to reduce head losses the suction pipe should be oIlimited length ma[8 ÷ 10 mand with a diameter larger than the pump inlet.

Distance between pump and water leYel shouldn’t be more than 4 ÷ 6 m when using pump at the best eI¿ciency point. The Yalue oIthe suction

not be subject to stress during pump operation.

Ensure in suction that:

- NPSH

aYailable is 1 meter appro[. higher than the NPSH reTuested by the pump and that Iriction losses in suction pipebendsIoot YalYe and

¿lter do not e[ceed 1 meter.

- Suction pipe has a diameter larger than the inlet oIpump and that the horizontal section oIthe suction pipe does not e[ceed a gradient oI2.

- All Moints are perIectly airtight.

- Anchorages and supports to preYent damages and possible breakage oIsuction Àange are properly secured.

- The suction pipe has not narrow bends and diameter Yariations.

Ensure in delivery that:

- All pipes and ¿ttings are adeTuately dimensioned to reduce pressure losses and to withstand the ma[imum operating pressure oIthe pump.

- A gate YalYe is ¿tted to regulate deliYery Àow.
