3.4 Operation
The liquid is suctioned with a minimum supply
pressure on the suction side (A). The pump increases
the pressure. The liquid leaves the pump on the
delivery side (B).
A Suction side
B Delivery side
Submersible sewage pumps that have been
equipped with a build-in floater are automatically
switched on and off when reaching a high or low
liquid level respectively.
Solid constituents from the wastewater can pass the
impeller without problems due to the large free
passage opening of the submersible sewage pump.
The performance (capacity and head) of the pump is
determined by the motor power and the impeller type
of the installed submersible sewage pump.
Table 3: Submersible sewage pump version
3.5 Operation of the automatic
level regulation A-series
A-Series switching levels
3.5.1 One pump operation
The pump will randomly start at level S2 or S3 and
will switch itself off at the lowest off switching level
after the initiation phase. The times between the
levels S3, S2 and S1 and the lowest off switching
level are saved in the system memory.
The pump will start at level S2 or S3 during the
following 7 switching cycles. The choice is random.
The off switching moment will be calculated based on
the number of saved starts between the levels S3, S2
and S1 and the lowest off switching level. When the
pump has completed 7 switching cycles based on the
previous calculation, the time measurements and the
detection of the lowest off switching level is repeated
and saved and the newly calculated pumping time is
assigned to the pump. The time will be saved that is
required to reach level S3, S2 or S1 when wastewater
continues to flow in. The period during which the
pump is operational will be adjusted to this.
When the pump has not been operational for a period
of 24 hours, the pump will start until the lowest off
switching level is detected. The test run will be
automatically activated after every 24 hour period
when the water level has not demanded a pump start.

The pump sends coded impulses to report failures.
Special modules can decode these impulses and can
specify the failures through failure lights or optical
contacts.
3.5.2 Two pump operation
The different operational phases of the pump are
combined through an algorithm in two pump
operation which enables the pumps to recognise
each other. The ratio of pumping times between
levels S3, S2, S1 and the lowest off switching level
are saved individually for each of the two pumps. The
pumping time that is calculated is assigned to the
following 7 pump cycles. Volume detection is
performed independently after every eighth pump
cycle.
The pumps can be operational simultaneously or in
sequence because the choice for starting one of the
pumps is random at level S2 or S3. When the water
level drops to below level S1 in relation to a pump that
is not operational, this pump will conclude that a
partner pump is available. The information about
there being a partner pump will be saved in the
memory of both pumps. The pump that has just been
operational, will save level S3 as the on switching
level. The pump that was not operational and which
detected the water level has dropped up to below
level S1, will now save level S2 as the on switching
level.
The two pumps will switch on in turns to on switching
level S2 when the water level drops to below level S1
of the pump that was currently not operational. When
the pumps have detected that there is a partner
pump, they will be switched on in turns when level S2
has been reached.
When sewage continues to flow into the pump sump,
the time is saved that is required to reach level S2
and level S1. The pumping time will be corrected
based on this. The same correction method can be
used for volume detection to compensate in changes
in the required pumping time when a partner pump is
available.
When one pump cannot supply sufficient pumping
capacity to drain away the incoming wastewater, the
second pump will be switched on when level S3 is
reached. You can determine when the pumps should
be switched off depending on the speed at which the
pump sump fills up and the time that is required for it
to be pumped and emptied. This can be determined
by both calculation and detection of the lowest off
switching level.
When one or both pumps have not been in operation
for a period of 24 hours, the pump or pumps will start
until the lowest off switching level has been detected.
The test run will be automatically activated after every
24 hour period when the water level has not
demanded a pump start.
3.5.3 Points of special interest
It is very important that the vent hole of the pump
housing is opened because the pump continues
running until the pump suctions air every eighth cycle.
ATTENTION
When installing a pump with an
automatic level regulation, the pump
must be at least 20 cm from the wall.
ATTENTION
The pump must be installed in such a
way that the inflow of the drain can
never reach the sensors for the level
regulation.
When a pump with automatic level regulation detects
that the water level is still above level S3 after 16
seconds, the pump will stop for a period of 3 seconds
will give a coded report for high water. A pump with
automatic level regulation must, therefore, only be
used in a drain.

4 Transportation
4.1 Transport
WARNING
Lift the pump, if necessary using a hoist
and suitable slings. Attach the slings to
the hoisting eyes on the packaging,
where present.
WARNING
The pump must be hoisted according to
the current hoist guidelines. Only
qualified personnel are allowed to hoist
the pump.
1. Transport the pump in the position as indicated
on the pallet or packaging.
2. Make sure the pump is stable.
3. Observe the instructions on the packaging (if
present).
4.2 Storage
4.2.1 Storage preparation
1. Spray clean the pump and the impeller in the
pump housing well using clean water.
2. Store the pump in a dry and frost-proof location.
4.2.2 Inspection during storage
1. Turn the impeller every three months. This will
prevent sticking of the running seals.
2. Have the pump inspected before putting it into
operation again after a storage period of 6
months or longer.

5 Installation
5.1 Mechanical installation
WARNING
Remove all cables and hoisting chains
from the pump sump. Prevent thus that
they can be sucked and damaged by
the pump.
WARNING
Never allow the pump to drop from the
feeder cable or delivery pipe. Use a
chain or a sufficiently strong cable that
is attached to the grip of the pump.
WARNING
Do not use the pump in locations where
there is freezing danger.
•Take the pump out of the packaging and check
for any transportation damage.
•Check whether the delivery is complete based
on the included Production Order Combination
List. Contact DP-Pumps if the delivery is
damaged and/or incomplete.
•Position and assemble the pump system on a
suitable surface or suspend the pump using the
grip.
•Position the pump on a paved surface when
there is mud and sand.
•Check whether the pump impeller can turn
freely.
•Make sure that the distance between the bottom
and the supply (A) is at least the same as the
free passage, see the technical information.
•Assemble, if required, a non-return valve in the
delivery pipe to prevent liquid flowing back. The
swing check valve must be installed at least 2 m
from the pump for the “A" version pump.
•Assemble (if possible) a globe valve on the
delivery side.
•Install the highest point of the delivery pipe
above the drain pipes of the street (ground level)
to make sure that a drain return flow is not
possible.
5.2 Electrical installation
WARNING
Only authorised personnel are allowed
to make electrical connections to the
motor in accordance with local
regulations.
Electrical connections:
•Make sure that the motor specifications
correspond with the power supply to which the
pump motor is connected. Consult "Electrical
diagrams" in the annexes for the correct
connection diagram.
•Connect the motor using a motor safety switch.
The setting must be the same as the motor
amperage as listed on the identification label in
relation to a direct start (DOL; Direct On Line).
•Connect the pump in accordance with the
electrical diagram that can be found in the
junction box.
•When the pump is being connected through a
frequency transformer, the motor must be
provided with a suitable “shielded” cable
specially for this situation. The temperature
protection in the pump must also be connected
to the frequency transformer. Range 30-50 Hz

12
5.3 Commissioning
WARNING
The pump must not be switched on
when it does not contain any liquid.
The direction of rotation of the pump is clockwise
seen from the top of the pump (A). The reactive force
will cause a shock movement in the opposite direction
(B) when started up.
ATTENTION
In case of a 3-phase motor the rotating
direction can be changed by
exchanging two of the three phase
wires.
ATTENTION
You are allowed to reduce the
submersible level up to the set point
specified in 9.1 Technical specifications
when operation is intermittent.
ATTENTION
The pump must be completely
submersed when operation is
continuous.
Check whether the submersible sewage pump
switches on and off at the correct liquid levels when
commissioning. Fill the drain up to the on switching
level of the pump. Use the liquid to be pumped or
clean water.
1 Check whether the pump switches on
automatically.
2 Check whether the pump switches off
automatically when reaching the off switching
level.
3 Check whether liquid is not returned from the
delivery pipe in the drain.
ATTENTION
Drill a small hole for venting at the
highest point of the pipe system (just
before the swing check valve) should
air remain enclosed in the pump
housing. Provide the hole with a
stainless steel nipple to ensure it
cannot become rusted up. Remember
that liquid can squirt from the drilled
hole.
ATTENTION
The DRV6/8 and DRS3 have been fitted
with a special bolt that can be removed
when there are problems with air
staying in the pump housing. The bolt
can be found on the other side of the
delivery connection under the motor
cable inlet.

7 Maintenance
7.1 Maintenance
WARNING
Disconnect the power supply to the
system before performing maintenance
work, and protect this disconnection.
WARNING
Remember that the motor can be hot
when it has just been switched off.
WARNING
Clean the pump with clean water before
carrying out maintenance work.
WARNING
Ensure that the guide clamp does not
become jammed on the guide bars if a
tackle is being used to remove the
pump from the drain.
Regular maintenance will promote the permanent
good operation of the installation. DP-Pumps has its
own maintenance department with specialised
engineers. A draft maintenance contract is available
upon request.
7.1.1 Maintenance schedule
The pump must be checked every 4000 operational
hours or at least once a year. We recommend
carrying out an overhaul every 5 years.
The maintenance interval should be adjusted when
operational conditions are heavier.
The bearings of the pump have been lubricated
for life and, therefore, do not require maintenance.
7.1.2 Oil chamber check
ATTENTION
All pumps have a closed, maintenance-
free system. Only the pumps of the DRK
type or in the HT or E version have a
checking option.
Check the oil chamber for any leaks of the seals.
1 Remove the inspection plug of the pump
housing.
2 Position the pump in a horizontal position with
the inspection opening downwards.
Any liquid that may be present in the pump housing
can now low out through the opening. Check the
composition of the liquid to discover any leaks.
Liquid Cause
Clear oil No leaks.
Lightly coloured oil A small quantity of moisture is
allowed.
Water/oil Not allowed; the seal or pump is
leaking1
1. Contact the supplier.
Overpressure Not allowed; seal or motor is
leaking1

15
7.1.3 Checking and cleaning the shredder
device (DRS)
Disassemble the shredder device and suction cover
and clean and perform an inspection. Next, install the
shredder device according to:
1 Position the impeller with the cutter head on the
pump shaft.
2 Secure the impeller.
3 Turn back the adjusting screws of the suction
cover up to the flange to ensure they no longer
protrude.
4 Install the suction cover in the pump housing.
5 Press the suction cover until the flange is on the
impeller everywhere.
6 Tighten the adjusting screws until the impeller is
just turning freely (gap = 0.3mm +/- 0.1mm).
7 Tighten the fastening bolts tightly.
ATTENTION
Again check whether the impeller can
turn freely.
7.2 Taking out of operation for a
long interval
Turn the impeller every three months. This will
prevent seals from sticking.
Protect the pump against freezing if there is a risk of
frost. Proceed as follows:
1. Close all globe valves.
2. Remove the pump from the drain.
3. Make sure the pump is cleaned correctly by
spraying with a powerful water jet.
4. Store the pump in a dry and frost-proof location.
