Once the pumps have been inserted in the drums and after connecting them to the pipes complete with distribution guns,
they can be started up following the procedures described below.
This procedure requires simple operations which, in designing the machine and, more precisely, the grease and oil transport
line, took into consideration the work execution methods that the operators carry out in the various phases of lubrication
and greasing, oil top-off, etc.
•
Opening the compressed air valve, the pump starts up and the entire oil/grease output pipe pressurises until
reaching the set adjustment value. Once this value has been reached, the pump stops
•
Acting on the oil/grease output gun, the product is delivered and the pressure in the circuit consequently decreases.
The pump starts up until the set pressure value is restored.
