OPERATING AND MAINTENANCE MANUAL
MD SERIES DIESEL FUEL PUMP
The temperature, density and viscosity of the liquid to be pumped, as well as the altitude
of the place of installation can affect the performance of the pump. The table below
shows the recommended temperatures of the liquid to be pumped in relation to the pump
materials.
Hydraulic pump
T(Cº)
The electric surface pumps can be used both for domestic and commercial uses (shops,
light industry and agriculture). Special attention must be paid to the number of machine
starts during normal operation. The instructions to be followed regarding the number of
starts / hour are shown in the following table
No. Starts
kW
The higher the power of the machine, the lower will be the maximum permissible number
of starts. To regulate the number of pump starts / hour if there are pressurisation
units, adjust the pressure switch settings to increase the differential pressure "ΔP" (see
relative section), or increase the capacity of the tank (add additional ones identical to
the existing one or replace it with a larger one). Pay particular attention to the operation
of the electric pumps with "press control" and / or "pressure-flow regulator"systems: a
minimal and imperceptible leak in the system can cause the electric pump to start-stop
a high number of times and affect its service life. We recommend that you install these
devices together with an autoclave tank, even a small capacity one (0.5 - 1 litres). The
electric pumps referred to will be able to withstand a maximum working pressure (equal
to suction pressure + head pressure with the delivery valve closed) of:
