Safety Devices; Intended Use - Comet BPS TANDEM Instrucciones Para El Ensamblaje Y El Mantenimiento

WARNING
• The machine integrating the pump must always feature at least the safety devices mentioned below.
• In case of repeated tripping of the safety valve, stop using the machine in which the pump is integrated
immediately and have it inspected by a Skilled Technician.
Pressure unloader/regulation valve.
This is standard for certain versions and is available as an optional accessory for others
This valve, suitably set by the Manufacturer, allows regulating the operating pressure and permits the
pumped fluid to flow back towards the bypass duct, thus preventing the accumulation of dangerous
pressures when the delivery line is closed or when attempts are made to set pressure values above
the maximum ones allowed. If a pressure limit/adjustment valve has devices to intercept/distribute
the pumped liquid (e.g. taps), it is usually called a PUMP CONTROL UNIT. To keep things simple, in
the manuals the term CONTROL UNIT will be used both for the pressure unloader/regulation valve
and for the pump control unit.
Safety valve.
This is standard for certain versions and is available as an optional accessory for others
This valve is suitably calibrated by the Manufacturer. It releases any overpressures in case of a fault
occurring in the pressure adjustment system.
Pump shaft protection.
This is standard for certain versions and is available as an optional accessory for others.
It is to prevent the operator from coming into contact with the moving parts of the pump shaft
WARNING
• The pressure unloader/regulation valve and the safety valve are calibrated either by the pump
Manufacturer of by the Manufacturer of the machine in which the pump is integrated. Never alter the
calibration of the pressure unloader/regulation valve: only ever operate on this by means of the
relative knob. Never alter the calibration of the safety valve.
• Any drainage from the safety valve must not leak into the environment.
• Should the protection of the pump shaft break or be damaged, the machine which incorporates the
pump must not be used until it has been tested by a Skilled Technician.
• Do not place hands or feet on the pump shaft protection
WARNING
• The pump must not be run by itself. It is only meant to be integrated in a machine.
• The pump must only be integrated in machines used for the following purposes:
- treating crops in agricultural and gardening applications;
- pumping water-based detergents and dyes;
- pumping water which is not for human consumption.
• The pump must not be integrated in machines for pumping:
- water based solutions whose density and viscosity is greater than those of water;
- solutions of chemical products if it is not known that they are compatible with the construction materials
of the pump
- seawater or water with high salt concentration;
- fuels and lubricants of all kinds and types;
- inflammable liquids or liquefied gases;
- edible liquids;
- solvents and thinners of all kinds and types;
- all paints;
