Beware of rotating parts!
The moving parts can crush and sever limbs. Never
reach into the pump unit or the moving parts during
operation. Switch off the machine and let the moving
parts come to a rest before maintenance or repair
work!

2.7. Safety and control devices

Our products are equipped with various safety and control
devices. These devices must never be dismantled or
disabled.
Equipment must be checked by an electrician for proper
functioning before start-up (see the "Electrical Connection"
data sheet). Please remember that certain equipment
requires a decoder device or relay to function properly. This
decoder can be obtained from the manufacturer or a
specialist electronics dealer.
Personnel must be informed of the installations used and
how they work.
Caution
Never operate the machine if the safety and monitoring
devices have been removed or damage, or if they do
not work.

2.8. Pumped fluids

Each pumped fluid differs in regard to composition,
corrosiveness, abrasiveness, TS content and many other
aspects. Generally, our products can be used for many
applications. For more precise details, see chapter 3, the
machine data sheet and the order confirmation. It should
be remembered that if the density, viscosity or the general
composition change, this can also alter many parameters
of the product.
Different materials and impeller shapes are required for
different pumped fluids. The more exact your specifications
on your order, the more exactly we can modify our product
to meet your requirements. If the area of application and/or
the pumped fluid change, we will be happy to offer
supportive advice.
When switching the product into another pumped fluid,
observe the following points:

Products which have been operated in
sewage or waste water must be thoroughly
cleaned with pure water or drinking water
before use.

Products which have pumped fluids which are
hazardous to health must always be
decontaminated before changing to a new
fluid. Also clarify whether the product may be
used in a different pumped fluid.

With products which have been operated with
a lubricant or cooling fluid (such as oil), this
can escape into the pumped fluid if the
mechanical shaft seal is defective.
Danger - explosive fluids!
It is absolutely prohibited to pump explosive liquids
(e.g. gasoline, kerosene, etc.). The products are not
designed for these liquids!

2.9. Sound Pressure

Depending on the size and power (kW), the pump has a
sound pressure of about 40dB (A) to 70dB (A) during
operation. However, the actual sound pressure depends on
several factors. These are, for example, the type of
installation and set-up, mounting of accessories, piping,
operating point, immersion depth, and much more.

3. General Description

3.1. Use

The Sekamatik 10 E 8M is used for pumping household
wastewater that is free of faeces. Installation of sinks or
basins, plus an additional drainage object, such as a
shower, bath, dishwasher, or a urinal, in rooms below the
backflow level of the sewer (rooms in the basement or
cellar), or without adequate slope to the next sewage
collection pipe. The Sekamatik 10 E 8M is suitable for
waste disposal for up to two sanitation units. A diameter of
1" is sufficient for the pressure line to the next sewage pipe.
The Sekamatik 10 E 7M is used for pumping household
sewage containing faeces. Installation of toilet, plus sink
and urinal or bidet, or shower in rooms below the backflow
level of the sewer (rooms in the basement or cellar), or
without adequate slope to the next sewage collection pipe.
The Sekamatik 10 E 7M is suitable for waste disposal for
up to three sanitation units. The stainless steel cutting
mechanism of the built-in pump reliably crushes faeces and
toilet paper. Therefore, a diameter of 1" is sufficient for the
pressure line to the next sewage pipe. Direct connection to
the toilet allows installation behind the toilet with minimal
space required.
It is essential to ensure that no sanitary products
such as tampons, sanitary napkins, condoms, etc., as well
as non-cuttable materials such as glass, wood, metal (razor
blades, bottle caps), etc. enter the wastewater, since they
are not crushed by the cutter, will remain in the collection
container and may block the pump under certain
circumstances. Avoid dumping very fatty wastewater into
the lifting system.
The flow rate in the pressure line must be at least
0.7m/s.

3.2. Use types

The sewage lifting systems are designed for intermittent
duty:

Sekamatik 10 E 7M S3 30%

Sekamatik 10 E 8M S3 40%

3.3. Structure

The lifting systems are made of a non-rotting, water, gas
and odour-proof plastic container with a single-stage rotary
pump.
The containers have different connections:
