Fig. 2: Sectional drawing
1 Discharge nozzle 2 Suction nozzle
3 Shaft 4 Shaft seal
5 Impeller
The pump is designed with a horizontal fluid inlet and a vertical outlet. The hydraulic
system runs in common bearings and is connected to the motor via a shaft.
The fluid enters the pump via a suction nozzle (2) and is accelerated outwards by the
rotating impeller (7). In the flow passage of the pump casing the kinetic energy of
the fluid is converted into pressure energy. The fluid is pumped to the discharge
nozzle (1), where it leaves the pump. At the rear side of the impeller, the shaft (3)
enters the casing via the casing wall. The shaft passage through the cover is sealed
towards the atmosphere with a shaft seal (4). The shaft runs in a rolling element
bearing.
The pump is sealed by a mechanical seal with rotating torque-transmitting elements.

3.
Fit the joint ring on the transparent filter lid.
4. Screw the filter lid down until it touches the casing.
5. Fully open all connections.
6. Start up the pump.
⇨ After a few minutes, the pump should be primed and start to deliver fluid. If this
is not the case, re-fill the pump.
5.7 Checking the direction of rotation
WARNING
Temperature increase caused by rotating parts
Risk of injuries! Damage to the pump set!
▷ Never check the direction of rotation by starting up the unfilled pump set.
CAUTION
Drive and pump running in the wrong direction of rotation
Damage to the pump!
▷ Refer to the arrow indicating the direction of rotation on the pump.
▷ Check the direction of rotation. If required, check the electrical connection and
correct the direction of rotation.
The correct direction of rotation of the motor and pump is clockwise (seen from the
motor end).
1. Start the motor and stop it again immediately to determine the motor's
direction of rotation.
2.
Check the direction of rotation.
The motor's direction of rotation must match the arrow indicating the direction
of rotation on the pump.
3. If the motor runs in the wrong direction of rotation, check the electrical
connection of the motor and the control system, if applicable.

8 Trouble-shooting
Table 7: Trouble-shooting
Fault/Malfunction Causes
Remedy
1)
Motor does not start. Motor protection switch defective or
not calibrated properly
Check.
Correct mains voltage but insufficient
voltage at the motor terminals
Replace the power cable of the pump
set; make sure core cross-sections are
large enough.
Incorrect motor connection Observe the wiring diagram.
Pump does not prime. Suction lift is too high. Reduce the suction lift.
Pump casing and suction line not filled
completely
Fill completely.
Air ingress at the transparent lid Check that the joint ring is fitted
properly and provides tight sealing.
Air ingress at the suction line Check that the suction line is sealed
properly and has been laid with a
continuously falling slope (to prevent air
pocket formation).
Wrong direction of rotation (3-phase
motor)
Check electrical connections.
Discharge-side and suction-side shutoff elements fully or partly closed
Fully open the shut-off elements.
Specified performance data are
not achieved.
Wrong direction of rotation (3-phase
motor)
Check electrical connections.
Total head smaller than expected Use pump set with larger head/flow rate
or reduce head losses.
Filter fully or partly clogged Clean the filter basket.
Excessive pressure losses in the piping Reduce head losses (use pipelines with
larger diameters, reduce the number of
pipe elbows).
Air ingress on the suction side Check the suction line for tightness.
Mechanical seal leakage Defective mechanical seal Check all parts of the mechanical seal;
replace them if required.
Motor protection device has
tripped
Pump blocked. Check whether the pump can be rotated
by hand.
Pump not running Check that the room is sufficiently
vented.
Motor is running on two phases only
(three-phase motor)
Check electrical connections.
Wrong direction of rotation (3-phase
motor)
Check electrical connections.
Impermissible voltage drop Increase the voltage or increase the core
cross-sections.
1)
Pump pressure must be released before attempting to remedy faults on parts which are subjected to pressure. Disconnect
the pump from the power supply and allow it to cool down.
