15. OPERATING HAZARDS
The warnings about the risks involved in using a pump for lubricants must be read.
The operator must understand its operation and clearly understand the hazards connected to pumping pressurized grease.
Therefore we recommend the following:
Check the chemical compatibility of the material with which the pump is built with the fluid to be pumped (see chap. 4). An
incorrect selection could cause, in addition to damaging the pumps and pipes, serious risks for people (spillage of irritating
products that are harmful to health) and for the environment.
Never exceed the maximum operating pressure permitted for the pump and the components connected to it. In the case of
doubt, refer to the data specified on the machine plate.
Only use original spare parts.
If components must be replaced with others, make sure they are suitable for operating at the pump's maximum operating
pressure.
Note: Personnel must use protective devices, garments and tools in compliance with current standards with regard to the location
and the use of the pump both during work as well as during maintenance operations.
Power supply
Any type of intervention must not be carried out before unplugging the machine from power supply. Make sure that no one can
start it up again during the intervention. All the installed electric and electronic equipment, reservoirs and basic components
must be grounded.
Flammability
The lubricant generally used in lubrication systems is not normally flammable. However, it is advised to avoid contact with
extremely hot substances or naked flames.
Pressure
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause oil sprays
when disassembling components or fittings.
After long periods of inactivity, check the seal of all the parts subject to pressure.
Do not subject the fittings, pipes and pressurized parts to violent impacts.
Damaged flexible pipes or fittings are DANGEROUS and must be replaced.
Only original spare parts should be used.
Noise
Under normal operating conditions, noise emission does not exceed70 dB“A” at a distance of 1 metre (39.3 inches) from the
pump.

The use of the pump with grease with a consistency NLGI000 must be assessed on a case by case basis given the extreme difference in the sliding
properties of the compound, which depends both on the viscosity of the base oil as well as the soaps and additives that are used.

A comparison table is provided between the classification of NLGI lubricants (National Lubricating Grease Institute) and the
ASTM classification (American Society for Testing and Materials) for greases for the values that concern the pump.
For further information about the technical specifications and the safety measures to adopt, refer to the product safety sheet
(Directive 93/112/EEC) relative to the type of lubricant selected and supplied by the manufacturer.
ATTENTION: The warnings about the risks involved in using a pump for lubricants must be read. The user must
understand its operation using the user and maintenance manual.
ATTENTION!
Never try to stop or deviate any leaks with your hands or other body parts.
NOTE:The pump was designed to operate with lubricants with a maximum rating NLGI 000.

Use lubricants that are compatible with NBR gaskets.
Any internal residual lubricant used for assembly and testing purposes is 32 cSt oil
