Fault Possible causes Remedies
Dry dirt or rubber particles have de-
posited:
between the guides of the chamber
bottom and annular piston or
- between annular piston and bowl
bottom or
- between sliding piston and bowl
bottom.
Clean bowl parts.
Renew damaged gaskets.
Grease guides (see 4.2.4 - lubrica-
tion schedule).
The closing chamber is dirty. Dismantle bowl.
Clean closing chamber.
The bowl does not open or
not properly (cont.)
Gasket 2 of polyamide has a loose fit
in the groove of the bowl top.
Product seeps into the gasket groove
and presses the gasket out of the
groove while the sliding piston moves
downwards, so that there is no gap
for solids ejection.
Replace polyamide gasket (see
4.3.8).
The bowl does not empty
completely. Solids remain in
the bowl. The operating water capacity is too
low. Check line pressure and increase if
necessary.
Operating water data:
– Pressure 2 - 3 bar (with open
valve)
– Volume flow min. 1 800 l/h (gauge
the capacity by litres)
≅
1.0 l in 2 sec
Gasket 2 in the bowl top
wears too quickly. The product contains abrasive solids. Remove the abrasive solids by in-
stalling a strainer.
The operating water in the closing
chamber has diminished during a
long separating time (evaporation
etc.). Set the operating water pulse and
time (see manual of the control sys-
tem). The bowl opens during se-
paration.
Time pulse for the operating water in-
jection is too long. Set the operating water pulse (see
manual of the control system).
