Changes in the Power Units UP100 S309
In order to pursue a continuous improvement and standardisation
policy of its products, Bucher Hydraulics introduces
some changes in the power unit UP100, concerning
the following components: body, filter conveyor, gear pump
and suction group as follows:
- Power unit body
The S309 power unit body UP100 includes a cavity "b" as
seat of the check valve, that is placed 1 mm upward compared
to the S409 UP100 body (picture 1).
In order to facilitate the identification of the S309 UP100
power bodies, we mark on three sides such specific
classification codes. In this way, it is possible to identify
which pump type rigs the power unit, without disassembling
the tank (pictures 2)

- Filter Conveyor
The picture on the left shows the previous filter conveyor.
The new type, on the right, is the same assembled on
power Units UP110.

- Single Gear Pump
Detailed picture of the two S409-S309 different pumps
type.
The picture on the left shows the version AP100 series
S409, and on the right the pump series S309, that is externally
recognizable by the new back cover.
The two pumps are internally different as they have different
balancing plates.
This characteristic doesn’t allow the interchangeability
between series S409 and S309; in the S309 body UP100
it is possible to assemble the new pump series S309,
only.
UP100 S409 UP100 S309
- Suction group
The new back cover of the pump series S309, has the
suction placed exactly in the middle of the power unit
body.
This enable to use the same suction group, by reducing
consequently the model quantities for each different horizontal
assembling positions.
UP100 S409 UP100 S309
The width of pump series S309, as it is shown on the right
of picture below, is 5 mm longer than the series S409.
This increase is a constant for any pump displacement,
because generated by height increase of the back cover.
