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
(1)
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.

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.
15. OPERATING HAZARDS
Compliance with the essential safety requirements and the provisions specified in the machine directive was checked by filling
out prepared check lists that are contained in the technical file.
Two types of lists were used:
Risk assessment (UNI EN ISO 14121-1).
Compliance with the essential safety requirements Machine Directive –EC 06/42).
The risks that were not completely eliminated, but considered acceptable, are specified below:
Electrocution: this can only occur in the case of serious user incompetence.
Use of unsuitable lubricant: the types of fluids that are not compatible with correct pump operation are listed below. *
Contact with harmful fluids.
Lubricants with abrasive additives
Lubricants with silicone additives
Petrol – solvents – inflammable liquids
Corrosive products
Water
Food substances
* For more detailed information regarding product compatibility with particular fluids, contact the Dropsa S.p.A. technical
office
