7.1. Measures to be taken prior to start-up
The unit may be put into operation by specialized personnel.
Using the pump submerged in fluids or in a particularly aggressive or explosive/flammable
environment is prohibited unless it has been prepared ahead of time by the supplier for this
purpose.
Use gloves and eye protection as required by the lubricant safety data sheet.
DO NOT use lubricants that are aggressive to NBR gaskets. If you are unsure, contact the
Dropsa S.p.A technical office for a detailed list of recommended lubricants.
Never ignore health hazards and always follow sanitary regulations.
Always use suitable piping for the operating pressure.
Check the integrity of the pump.
Ensure that the pump operates at operating temperature and that the pipelines are free of any
air bubbles.
To determine the maximum operating pressure, it is necessary to know the pressure drop of the
pipeline connected to the pump outlet, depending on the length, temperature and type of
lubricant.
Depending on these variables to achieve a proper supply to the delivery point, you must always
ensure that the pipeline pressure loss plus the pressure required at the lubrication point does not
exceed the maximum pressure supplied for pump delivery.
