SERA FP 2000 [6/44] Fp can be largely dismantled and replaced the motor block

The convince with their compact
and robust construction as well as low energy consumption and
their adjustability. The  FP are being
offered in 7 performance variants. The correct performance
level is available for nano aquariums up to marine tanks.
Due to their plain design, the 
– 2000 can be placed unobtrusively in an aquarium. Their compact
shape also allows placing them in internal lters. The high water
agitation performance ensures constant conditions in an aquarium
and thus contributes to the stabilization of the biological system.
SAFETY PRECAUTION
All electrical units located in the water must be disconnected from
the mains/power supply before conducting work at the aquarium!

The  are particularly well suited
as operational pumps of internal lters in aquariums and as a
feed pump for aquatic systems. All versions with ceramic shaft,
beginning with FP 350, are suited for operation in marine water.

Depending on the version, different hoses (please see “Techni-
cal data”) can be connected via the hose connector (2.3). Push
the end of a hose over the connector. Before doing so, briey
immerse the hose end in hot water in case of hard or stiff hoses.
Now possibly secure the hose with a hose clamp.
The  FP can also be placed in an

The pump should be placed directly on the bottom of an aquar-
ium or at the aquarium glass, and be operated entirely sub-
merged. Make sure the pump does not draw in air.
Operation
Make sure there is no direct or indirect conducting contact to
persons before switching on the pump.
The pump begins to run upon plugging in the plug. The pump
can be adjusted to the desired performance level by turning the
rotary adjustment cap at the intake grid. The water ow through
the pump will be reduced when turning the cap in “–” direction.
The water ow will rise up to the maximum feed performance
when turning the cap in “+” direction.
The pump does not have an additional On/Off switch. The pump
is designed for permanent operation but must not run dry, as
the motor block is cooled by water and the ceramic bearings
are lubricated by water. Turn the pump off again and check
whether nothing is clogged if no water is delivered after a few
seconds. Switch the pump back on only afterwards.
Cleaning
All parts can be cleaned with a brush and a neutral detergent. Make
sure no detergent gets into the aquarium. Carefully rinse all cleaned
parts with clean tap water before reassembling the pump and put-
ting it back in operation in the aquarium. You can immerse the
running unit (2.4) and the motor block (2.1) in a descaler solution
for stainless steel parts if the pump is severely lime encrusted.
Please adhere to the information for use of the descaler solution.

The mechanical components of the 
FP can be largely dismantled and replaced. The motor block
(2.1) is embedded in plastic material for electric isolation and
therefore cannot be repaired.

Take the pump intake grid (2.7) off the motor block (2.1). Turn
the pump chamber cover (2.6) to the left by approximately 90°.
Pull the pump chamber cover straightly out of the motor block,
making sure the shaft (2.4.3) cannot break. In case the shaft
remains stuck in the motor block, pull it out rst before pulling
out the magnetic impeller (2.4.2). Reassembly takes place in
reverse order. Caution! When inserting the rotor into the motor
block it can suddenly rotate and be drawn in.
