7. Maintenance, Service, Spare Parts
Information for maintenance personnel
Before performing any maintenance operations on the
electric pump unit, make sure that the motor is
voltage-free.
Maintenance operations must be performed by skilled
and qualified personnel only. Use suitable equipment
and protection devices. Observe the accident
prevention regulations in force.
If pump must be drained, make sure that the drained
liquid does not cause damage or injuries.
The pump is supplied with a calibrated fork-shaped shim
designed to facilitate the motor coupling and replacement
operations.
7.1 Routine Maintenance
The pump does not require any scheduled routine maintenance.
In general, the checking of the following aspects, or some of
them, at varying intervals depending on the operating conditions
is recommended: pumped liquid leaks, delivery pressure, starts
per hour, noise, triggering of the electrical protections (relays,
fuses,…).
If the user wishes to draw up a maintenance schedule, related
deadlines depend on the type of liquid pumped and on the
operating conditions.
7.2 Extraordinary Maintenance
Extraordinary maintenance may be necessary in order to clean
the liquid end or replace the mechanical seal and other worn
parts.
7.3 Motor/Pump Coupling
The pump may be supplied without the electric motor. In this
case the calibrated fork-shaped shim is already inserted
between the adapter and the transmission coupling in order to
keep the impeller stack in the correct axial position. To prevent
damage during transportation, the pump shaft is held in position
by Styrofoam and two plastic straps. The bolts and nuts needed
to fasten the motor to the adaptor are not included. Refer to the
diagrams in Fig.U, Fig.V.to couple the pump to the motor.
7.3.1 Selecting the Electric Motor
If the pump alone has been bought, without the motor,
the safety of the coupled pump with a motor other
than those described in Lowara’s catalogue must be
guaranteed by the person making the coupling.
Single-phase or three-phase motors whose size and power
comply with the European standards can be used.
Use dynamically balanced motors, with half-
sized key in the shaft extension (IEC 60034-
14) and with normal vibration rate (N).
7.4 Replacing the Motor
Refer to the diagrams in Fig.U, Fig.V.
If the calibrated fork-shaped shim is not available, use a 5 ± 0.1
mm shim.

7.6 Service
Please contact the Sales and Service Department for any
request or information.
7.7 Spare Parts
Always specify the exact pump/electric
pump unit type and identification code when
requesting technical information or spare parts from the Sales
and Service department.
Use only original spare parts to replace any worn or
faulty components. The use of unsuitable spare parts
may cause malfunctions, damage and injuries.
Refer to the diagrams in Fig.Y, W, Z.
8. Disposal
Information for installation and maintenance personnel
