PRODUCT DESCRIPTION

Clarification must be sought as to whether the
pump can be used at all with another fluid.

2.7. Sound pressure

The pump has a sound pressure of less than
80 dB (A).
We recommend that the end-user takes an
additional measurement at the workplace once
the pump is running at its duty point and under all
operating conditions.
CAUTION: Wear ear defenders!
According to applicable laws and regula-
tions, ear protection must be worn if the
sound-pressure level is 85 dB(A) or more! The
end-user must make sure that this is complied
with!

2.8. Standards and guidelines used

The pump is subject to various European di-
rectives and harmonised standards. See the EC
declaration of conformity for precise information
about these.
In addition, various standards are used as a basis
for operating, assembling and dismantling the
pump.

2.9. CE marking

The CE marking is attached to the rating plate.
3. Product description
The pump is manufactured with great care and is
subject to constant quality controls. Trouble-free
operation is guaranteed if it is installed and main-
tained correctly.

3.1. Intended use and fields of application

ELECTRICAL hazard
When using the pump in swimming pools or
other basins that can be entered, there is a
risk of electrocution. Note the following:
• Use is strictly forbidden if there are people in
the basin!
• If there are no people in the basin, protec-
tive measures must be taken according to
DIN VDE 0100-702.46 (or the appropriate
national regulations).
DANGER - explosive fluids!
It is strictly prohibited to pump explosive flu-
ids (gasoline, kerosene, etc.). The pumps are
not designed for these fluids!
Rocsan SDL... submersible pumps are suitable for
intermittent and continuous pumping of waste-
water and sewage, as well as sewage containing
faeces, out of pump chambers and tanks in pres-
sure drainage systems.
NOTE
Cleaning cloths and wipes may lead to clogging
and blockages. Avoid such fluids by mechani-
cally cleaning the inflowing fluid beforehand.
Installation and operating instructions Salmson-Rocsan SDL
The submersible pumps must not be used for
pumping:
• Drinking water
• Rainwater, drainage water or other surface water
• Fluids containing hard components such as stone,
wood, metal, sand etc.
• Highly flammable and explosive fluids in pure
form
.
The intended use includes complying with these
instructions. Any other use is considered to be
outside the intended use.
3.1.1. Notes on compliance with DIN EN 12050-1 and
EN 12050-1
According to DIN EN 12050-1 (according to
the German preface) an Ex-rated certificate is
required for sewage pumps.
Based on EN 12050-1, Ex rating is not an explicit
requirement. The local regulations need to be
checked in each case.

3.2. Set-up

Rocsan SDL pumps are submersible sewage
pumps with an upstream macerator. The pumps
can be operated upright in a stationary and port-
able wet well installation.

3.2.1. Hydraulics
Rotodynamic hydraulics with upstream internal
(GUT GL...) or external (SDL GE...) macerator.
The macerator breaks up admixtures suitable for
cutting for transfer in a 1¼" discharge pipeline or
larger. The pressure side connection is designed
as a horizontal flange connection.
The hydraulics are not self-priming, in other
words, the fluid must flow in either automati-
cally or with supply pressure.
CAUTION! The fluid may contain hard compo-
nents!
Hard admixtures like sand/grit, stones, metals,
wood etc. cannot be cut by the macerator.
These admixtures can destroy the macerator
and the hydraulics and therefore lead to a
pump malfunction! Filter these admixtures
beforehand out of the fluid before they enter
the pump.
3.2.2. Motor
In the AC or three-phase current version, glanded
motors are used as the motors. The motor is
cooled by the fluid around it. The waste heat is
transferred directly to the fluid via the motor
housing. The motor may emerge during opera-
tion.
