pumping the following liquids:
• large quantities of drainage, surface and storm
water
• domestic wastewater with discharge from toilets
• wastewater with a high content of fibres
(SuperVortex impeller)
• industrial process water
• wastewater with gaseous sludge
• municipal and commercial sewage and
wastewater.
Stainless steel versions
The stainless steel versions are suitable for pumping
the following liquids:
• industrial process water containing chemicals
• aggressive or corrosive drain water and effluent

Approvals
SE1 and SEV pumps have been tested by Dekra /
KEMA. The explosion-proof version hold two
examination certificates:
• ATEX(EU): KEMA 04ATEX2201X
• IECEx: IECEx DEK 21.0017X.
Both certificates have been issued by Dekra. The
standard versions of SE1 and SEV pumps are tested
by VDE.
Approval standards
The standard variants are approved by TÜV
Rheinland (LGA) notified body under the Construction
Products Directive according to EN 12050-1 or EN
12050-2 as specified on the nameplate.
Explanation of the Ex approval
The SE1 and SEV pumps have the following
explosion protection classifications:
• CE 0344 II 2 GD Ex db eb h mb IIB T4, T3 Gb;
Ex h mb tb IIIC T135 °C, T200 °C Db.
Directive or

Potentially explosive environments
Use explosion-proof pumps for applications in
potentially explosive environments.
SE1 and SEV pumps
must under no circum-
stances pump combusti-
ble liquids.
The classification of the
installation site must be
defined by the owner.
Special conditions for
safe use of explosion-
proof pumps:
1. Make sure the mois-
ture switch and ther-
mal switches are
connected in the
same circuit, but
have separate alarm
outputs (motor stop)
in case of high hu-
midity or high tem-
perature in the mo-
tor.
2. Bolts used for re-
placement must be
class A2-70 or better
according to EN/ISO
3506-1.
3. Contact the manu-
facturer for informa-
tion on the dimen-
sions of the
flameproof joints.
4. The level of the pum-
ped liquid must be
controlled by level
switches connected
to the motor control
circuit. The minimum
level depends on the
installation type and
is specified in these
installation and oper-
ating instructions.
5. Make sure the per-
manently attached
cable is suitably me-
chanically protected
and terminated in a
suitable terminal
board placed outside
the potentially explo-
sive area.
6. The pumps have an
ambient temperature
range of -20 to +40
°C and a maximum
process temperature
9
English (GB)

of +40 °C. The mini-
mum ambient tem-
perature for a pump
with a water-in-oil
(WIO) sensor is 0 °C.
7. The thermal protec-
tor in the stator wind-
ings has a rated
switch temperature
of 150 °C and must
guarantee the dis-
connection of the
power supply. The
power supply must
be reset manually.
8. The control unit must
protect the WIO sen-
sor against short cir-
cuit current. The
maximum current
from the control unit
must be limited to
350 mA.
9. For painted pumps,
minimise the risk of
electrostatic dis-
charge by:
• Earthing (mandato-
ry).
• In dry installations,
keep a safety dis-
tance between
pumps and walking
paths.
• Use wet cloths for
cleaning.
10. The WIO sensor
must be used only
with a galvanically
isolated circuit.
11. The lock nut of the
cable connector
must only be re-
placed with an identi-
cal one.
Transporting the product
The pump may be transported and stored in a vertical
or horizontal position.
CAUTION
Crushing hazard
Minor or moderate per-
sonal injury
‐Make sure the pump
cannot roll or fall
over.
