Turbelle
Submerged Centrifugal Pumps 2002/4002
®
General aspects
Turbelle
pumps are designed for continuous operation. Switch off
®
periods of 1 sec. will not affect their smooth operation.
The Turbelle
submerged centrifugal pumps may be used indoors
®
only. The temperature of the aquarium water and the ambient air
should not exceed 35° Celsius. The mains cable is firmly sealed
in the motor block and can only be replaced completely with motor.
Installation
The motor housing is screwed on mounting clamp (13) / auxiliary
support bracket (Z1) which provides secure and vibration resist-
ant fastening. Therefore screw down tightly! The nylon handle of
the straining screw can be removed. Subsequently tighten the
screw with a screwdriver.
When installing a Turbelle
®
pump in a lighting box, make sure that
there is plenty of openings to allow sufficient cooling of the pump
motor. Inadequate air supply may cause damage to the bearing,
et cetera.
Turbelle
pumps are designed to operate with the impeller housing
®
immersed (the water level should be a minimum of 2 cm above
the impeller housing (18)). However, the water level must never
be higher than 2 cm below the motor housing because otherwise
there is the danger that water enters the motor.
Never install the mounting clamp (13) and the mounting bracket
(Z1) partially submerged as damage may occur by electrolytic
dissolution at the transition between air and the aquarium water. A
complete submergence is possible without adverse effects.
Attachment on a vertical aquarium edge
Screw the Turbelle
pump with the mounting clamp (13) attached
®
to the aquarium edge (Fig. 2 or 3).
Attachment on a horizontal aquarium edge
Screw the Turbelle
pump with the mounting clamp (13) and
®
additional mounting bracket (Z1) to the aquarium edge (Fig. 4).
The holding force is increased considerably, if about 1-2 mm of
silicone adhesive is applied to the pressure cup and the knobbed
nylon edge of the holder before mounting. After curing the clamp
will no longer slip.
Attachment in the TUNZE SYSTEM (Fig. 5)
When fitting in the TUNZE SYSTEM the TS-Turbelle
is used to attach the Turbelle
®
Attention!
The motor section must not get in touch with water ! Protect your
Turbelle
pump against splash water ! Do not attach a gas
®
discharge unit nearby.
Initial operation
The pumping capacity of all Turbelle
without any problems by constricting the diameter of the outlet by
a regulating screw made of plastic, et cetera, for example.
Before switching on your Turbelle
you are operating it on 220-240 VAC / 50-60 Hz (USA type: 115
VAC / 60 Hz). If you are installing your Turbelle
we recommend that you allow the pump to warm up to room
temperature for about an hour, as very cold bearings may easily
block. To prevent electrical leaks and loose connections, no
switches have been provided on Turbelle
control Turbelle
pumps we recommend the use of Turbelle
®
powertimer 708/7082.
If your Turbelle
pump does not start up properly after an extended
®
down period, soak the impeller housing in lukewarm water for
approx. 5 min. to dissolve any deposits on the pump shaft and the
bearing. If necessary turn the impeller a few times with the index
finger.
Cleaning
From time to time, or at least once a year, you should have an
expert clean the unit, if the motor is covered with a lot of dust. The
impeller housing may get covered with algae and other ooze.
Remove the mains plug for cleaning. Subsequently slide up the
clamping ring on the shaft (9) and pull down the impeller housing
(18) complete with shaft (12). Now remove the screw socket (20)
holder (Z2)
®
. Mounting clamp (13) is not required.

pump, please make sure that

pump in the winter,

pumps. To switch and
®
from the impeller housing. Hold the shaft (12) in one hand and use
the other hand to unscrew the impeller (19) like a wing screw.
Note ! Take care not to loose the washer (16) of impeller
bearing. Make sure that the rounded side of the washer is
down against the impeller bearing (18).
In warm water with a bit of detergent and cleaned with a brush, the
Turbelle
will turn out almost new ! Screw shaft and impeller
®
together again. Use the straining ring (9a) to hand tighten the
impeller housing (18) to the shaft tube (9).
What can you do, if...
...the motor stops working.
If the motor on your Turbelle
thermostat switch disconnects the power supply (at approx. 85°
Celsius motor temperature). After a cooling down period, the
motor switches itself on again. However, disconnect the unit from
the mains supply and try to determine the cause of overload. A
foreign body, for example, may block the pump, the ambient
temperature may exceed 35° Celsius (lighting box without suffi-
cient cooling), or a short circuit may have occurred due to a water
damage.
... the pump starts rattling.
Pull the pump section with shaft off downwards. Check whether
the motor is rattling. In the affirmative, the motor bearings (4) have
to be replaced. In the negative, the source of the fault has to be
looked for and removed on the shaft and pinion (12) or on the
impeller bearing (17). If necessary, these parts have to be re-
placed.
... the motor bearings start rattling.
The motor bearings are designed to run maintenance free for their
whole life time. They must not be oiled. After 3 to 5 years bearing
noises (depending on the operating conditions) may occur. In this
case the motor bearings have to be replaced.
... running noises can be heard from the housing.
This may occur, if excessive dust or dirt is sucked into the motor
so that the intake fan produces noise. Please refer to the chapter
on „Cleaning".
...the pump accidentally falls into the water.
First disconnect the unit from the mains supply! Take Turbelle
of the water. Permit the water to drop off, and let the housing dry.
If the motor noise turns louder during operation, the motor bearings
have to be replaced.
... rust-like deposits form on the high-alloy steel parts (1, 10,
13, 15, Z1).
This rust-like deposit is a deposit of iron (oxides) by the aquarium
water, which is not produced by the corrosion-resisting holding
device. The deposit can be removed with a brush. Rust is
biologically harmless. Never install the mounting clamp (13) and
the mounting bracket (Z1) partially submerged as damage may
occur by electrolytic dissolution at the transition between air and
the aquarium water.
