GENERAL REFERENCE
(1)
Installation
The direction of rotation of single-rotation pumps
must be the same as that of the drive shaft.
Check that the coupling flange correctly aligns
the transmission shaft and the pump shaft.
Flexible couplings should be used (never rigid
fittings) which will not generate an axial or radial
load on the pump shaft.

Starting up
Check that all circuit connections are tight and
that entire system is completely clean. Insert the
oil in the tank, using a filter. Bleed the circuit
assist on filling. Set the pressure relief valves to
the lowest possible setting. Turn on the system
for a few moments at minimum speed, then
bleed the circuit again and check the level of oil
in the tank. In the difference between pump
temperature and fluid temperature exceeds
10° C, rapidly switch the system on and off to
heat it up gradually. Then gradually increase the
pressure and speed of rotation until the pre-set
operating levels as specified in the catalogue are
attained.

Periodical checks-maintenance
Keep the outside surface clean especially in the
area of the drive shaft seal. In fact, abrasive
power can accelerate wear on the seal and
cause leakage. Replace filters regularly to keep
the fluid clean. The oil level must be checked
and oil replaced periodically depending on the
system's operating conditions.
