Pump and tank
Pump SVH can be ordered in left or right-hand versions depending on the
direction of rotation of the power take off.
The tank must be equipped with oil pipes (1) around the return filter for
optimal de-aeration of the oil. The size of the oil filter (2) must correspond to
4 x the effective pump flow with a degree of purification of 10 μm absolute.
Should the system require cooling for optimal efficiency, a cooler must be
placed on the return line or in a separate circuit. The amount of oil in the tank
should correspond to the maximum pump flow during 2 minutes. A breather
filter (3) of 10μm must be installed so that moisture and contaminants cannot
enter the tank. The air flow at 0.1 bar pressure difference should at least be
equal to the maximum oil flow.
The tank should be positioned close to the pump on a level so that the lowest
oil level does not come below the pump level. Pipes are routed so that air
pockets cannot form to prevent cavitation and noise. Any suction shut-off
valve (4) must have an internal diameter that is not less than the suction line.
There must be a pressure relief valve (5) in the system. It must be installed
close to the pump if there are long pipes to the operating valve.
