If hot or cold parts can cause risk, they have to be protected against the accidental contact.
The protections against the accidental contact with moving parts must not be removed when
The loosing of dangerous material must be discharged avoiding damages for people and
environment. Respect the laws and the regulation in force.
Warning about safety during the maintenance inspection and mounting phases.
The plant manager must ensure that the maintenance inspection and mounting of the pumps
will be carried out by qualified personnel. Moreover the personnel must be adequately
informed about the functioning of the pump.
All operation on the pump must be carried out with the stopped pump.
The pump must be depressurized and cooled down before any operation.
Transformation and production of spare parts.
The transformation or alteration of the pump is admitted only in case of previous accordance
with the manufacturer. The original spare parts and manufacturer authorised accessories
contribute to a safer functioning and an optimized pump performance.
The use of unauthorised components cancel manufacturer responsibilities for potential
Not admitted functioning modes.
The safe functioning of the pump is warranted only in case of proper use and in accordance
with all national law in force.
Our pumps are projected for predetermine working condition, in no case the reported
exercise conditions can be passed. Use the pump only for the purpose and condition
as it was sold and projected.
If you have intention to modify these condition, please contact Gianneschi Pumps and
Blowers for any assistance. Particularly in case of toxic dangerous or aggressive fluids.
General criteria for a correct pump functioning are:
Compatibility between the pumped fluid and the pump materials.
The correct retain of seals, particularly the shaft’s seal.
The pump components resistance related to the pressure and temperature of the pumped
This type of pump is volumetric type so theoretically it can produce a infinity pressure. In case
of closed delivery pipe (e.g. for an obstruction or accidental valve closure) the delivery
pressure can reach a multiple of the admitted plant pressure. It can cause, for example, a
delivery pipe explosion. On the plant is necessary to install adequate safety equipment as
pressure switch or safety disc with return pipes.
Maintenance and reparation.
During any assistance check the motor against an accidental start.
