13. TRANSFER AND TRANSPORTATION
Before shipment, the pumps are carefully packed inside a cardboard box. During transport and storage of the equipment, pay
attention to the direction indicated on the box. On receipt, check that the packing is not damaged and store the equipment in a
dry place.
Lift the equipment bearing in mind the direction indicated on the box.
The components of the pump can withstand temperatures during storage from -20°C to + 65°C. However, in order to prevent
damage, use must take place when the pump has reached a temperature of +5 °C.
14. PRECAUTIONS FOR USE
The warnings on risks using a lubricant pump implies must be carefully read.
The operator must be familiar with the functionality and clearly understand the dangers connected with pumping greases under
pressure. We therefore recommend:
Checking the chemical compatibility of the pump construction materials with the fluid that you intend to pump (see the table
at the end of Section 14). An incorrect choice could cause, in addition to damage to the pumps and the lines, serious risk to
personnel (leaking of products that are irritants and harmful to the health) and to the environment.
Use only original spare parts.
If you must replace components with others, ensure that they are suitable to function at the pump's maximum operating
pressure.
ATTENTION:
Note: Personnel must use protection equipment, clothing and tools that comply with the prevailing regulations in relation to the
location and the use of the pump both during operation and maintenance.
ATTENTION:
operation through the Operation and Maintenance Manual.
Flammability
The lubricant used in the lubrication circuits is a fluid that is not normally flammable. In any case, all possible measures must be
taken to prevent it coming into contact with very hot parts or naked flames.
Pressure
Before any operation, check for the absence of any residual pressure in all branches of the lubricant circuit, that could cause
spurts of oil in the event that fittings or components are disassembled. After long periods of inactivity, check the seal on all the
parts subject to pressure. Do not subject the fittings, pipes and the parts under pressure to violent impact. A damaged hose or
fitting is DANGEROUS. Replace it. We recommend using only original spare parts.
NOTE:
The pump is designed to work with maximum 220 cST grade lubricants. Use NBR-seal compatible lubricants. The lubricant
used for assembling and testing possibly remaining inside is 32 cSt oil.
15. OPERATING INDICATIONS
The pumps do not have particular contraindications except for the following points:
Operator contact with lubricant via ruptured/open pipes or during reservoir maintenance/filling procedures. Protection
against direct and indirect contact with the fluid must be provided by the user: The operator must be equipped with
appropriate PPE (ClassVIII – 626).
Use of unsuitable lubricant. Main prohibited fluids:
Lubricants with abrasive additives
Lubricants with silicon additives
Petrol – solvents – flammable liquids
Corrosive substances
Food substances
