3.3. Functionality
Rest period
The ball (pos. 3) is on the internal membrane (pos. 4) in the
membrane casing (pos. 5). Here the external membrane
(pos. 11) is bent facing outwards and forms an oil cham-
ber with the membrane casing.
Pump is working
The sewage is led through the valve casing (pos. 1) out-
wards into the pump it and the flushing begins. Through
the current into the valve, low pressure is created.
Through this low pressure, the oil moves from the exter-
nal membrane to the internal membrane.
After a set amount of time – through the current restrictor
(pos. 8) – there will be enough oil under the internal mem-
brane in order to life this. Here the ball will be transported
into the current channel. The ball then closes the exit of
the valve and the pump transports the sewage with the
normal power from the pump pit.
At the same time, high pressure is created in the valve,
which presses the oil back to the external membrane. If
the pump is turned off, the ball will fall back to the internal
membrane

4. Package, Transport, Storage
4.1. Delivery
On arrival, the delivered items must be inspected for dam-
age and a check made that all parts are present. If any
parts are damaged or missing, the transport company or
the manufacturer must be informed on the day of delivery.
Any claim made at a later date will be deemed invalid.
Damage to parts must be noted on the delivery or freight
documentation.
4.2. Transport
The product is delivered by the manufacturer/shipping
agency in suitable packaging. This normally precludes the
possibility of damage occurring during transport and stor-
age. The packaging should be stored in a safe place if the
location used is changed frequently.
4.3. Storage
Newly supplied products are prepared that they can be
stored for at 1 year. The product should be cleaned thor-
oughly before interim storage.
The following should be taken into consideration for stor-
age:
• Place the product on a firm surface and secure it
against falling over.
• We recommend a dry, frost-protected room with a
temperature of between 5 °C and 25 °C for storage.
• The machine must be protected from direct sunlight,
heat, dust, and frost.
• If the product has been stored for a long period of
time it should be cleaned of impurities such as dust
and oil deposits before start-up
If these rules are observed, your product can be stored
for a longer period. Please remember that elastomer parts
and coatings become brittle naturally. If the product is
to be stored for longer than 6 months, we recommend
checking these parts and replacing them as necessary.
Please consult the manufacturer.
4.4. Returning to the supplier
Products which are delivered to the plant must be clean
and correctly packaged. In this context, clean means that
impurities have been removed and decontaminated if it
has been used with materials which are hazardous to
health. The packaging must protect the product against
damage. Please contact the manufacturer before return-
ing!
