Warning
Prior to installation, read these
installation and operating instructions.
Installation and operation must comply
with local regulations and accepted
codes of good practice.

Warning
If these safety instructions are not
observed, it may result in personal
injury!
Warning
If these instructions are not observed,
it may lead to electric shock with
consequent risk of serious personal
injury or death.
Warning
These instructions must be observed
for explosion-proof pumps. It is
advisable also to follow these
instructions for standard pumps.
If these safety instructions are not
observed, it may result in malfunction
or damage to the equipment!

easier and ensure safe operation.
2. General description
The electronic Grundfos DP and EF pumps
incorporate a controller and motor-protective
functions. They only need to be connected to the
mains supply.
The controller offers the following benefits:
• Built-in level and dry-running sensors.
• Built-in motor protection.
• Pump alternation.
If several pumps are installed in the same tank,
the control logic incorporated in the pump will
ensure that the load is distributed evenly among
the pumps over time.
8
• Alarm relay output.
The pump incorporates an alarm relay output.
NC and NO are available and can be used as
required, for example for acoustic or visual
alarms.
• Anti-seizing system.
The anti-seizing system starts the pump at
programmed intervals to prevent the impeller
from seizing up.
• Random start delay.
This function ensures an even mains load when
several pumps are started at the same time after
an unintentional power cut.
The DP and EF pumps are portable and designed for
pumping domestic and industrial wastewater.
Two types of pumps are available:
• DP 10.50 and DP 10.65 drainage pumps
• EF 30.50 effluent pumps.
The pumps are designed for free-standing
installation.
DP 10.65.26 pumps can be installed on an autocoupling system.
Warning
Special conditions for safe use of
DP and EF explosion-proof pumps:
• Bolts used for replacement must be
class A2-70 or better according to
EN/ISO 3506-1.
• The thermal switch in the stator
windings with a nominal switch
temperature of 150 °C shall
guarantee the disconnection of the
supply; the resetting of the supply
shall be manually.

2.1 Applications
DP 10 pumps are designed for pumping
• drainage and surface water
• groundwater
• industrial process water without solids or fibres.
EF 30 pumps are designed for pumping
• drainage and surface water with sm all impur ities
• wastewater with fibres, e.g. from laundries
• wastewater without discharge from toilets
• wastewater from commercial buildings without
discharge from toilets.
The compact design makes the pumps suitable for
both temporary and permanent installation.
The pumps are designed for free-standing
installation.
DP 10.65.26 pumps can be installed on an autocoupling system.
2.1.1 Potentially explosive environments
Use explosion-proof pumps for applications in
potentially explosive environments.
Warning
The explosion protection classification
of the pump is CE II 2 G, Ex bcd IIB
T4 Gb.
The classification of the installation
site must in each individual case be
approved by the local fire-fighting
authorities.
Warning
The pumps must under no
circumstances pump combustible
liquids.
3. Operating conditions
The pumps are designed for intermittent operation
(S3). When completely submerged, the pumps can
also operate continuously (S1). See section
11.2 Operating modes.
The EF pumps are suitable for pumping effluent and
other liquids with solids up to 30 mm.
3.1 Installation depth
Maximum 10 metres below liquid level.
3.2 Operating pressure
Maximum 6 bar.
3.3 Operation
Maximum number of starts per hour, see WebCAPS
on www.grundfos.com.
3.4 pH value
Pumps in permanent installations can be used for
pumping liquids with a pH value between 4 and 10.
3.5 Liquid temperature
0 °C to +40 °C.
For short periods (maximum 15 minutes) a
temperature of up to +60 °C is allowed (standard
versions only).
Warning
Explosion-proof pumps must never
pump liquids with a temperature higher
than 40 °C.
3.6 Density of pumped liquid
Maximum 1000 kg/m3.
In the case of higher values, see WebCAPS on
www.grundfos.com, or contact Grundfos.

4. Approvals
The standard versions of the DP and EF pumps have
been tested by VDE.
The explosion-proof versions have been approved
by KEMA according to the ATEX directive.
4.1 Approval standards
All versions have been approved by LGA (notified
body under the Construction Products directive)
according to EN 12050-1 and EN 12050-2.
