3.2 Operating conditions
pH value
4-10.
Liquid and ambient temperature
34-104 °F (1 °C to +40 °C).
Density and viscosity of pumped liquid
Maximum density: 68.8 lbs/ft
3
.
Maximum kinematic viscosity: 1cSt (1 mm
2
/s).
Operating mode
The pumps are designed for continuous operation or for
intermittent operation. The maximum number of starts allowed
are shown in this table:
In order to avoid overloading the windings, seals and bearings,
the above numbers of starts must not be exceeded.
Enclosure class
IEC IP68.
Sound pressure level
Turbulence optimizer
Turbulence optimization is only possible if the pump is mounted in
the column pipe size that the pump is intended for. Turbulence
optimization is not possible if the pump is mounted in an oversize
column pipe.
4. Identification
4.1 Nameplate
The nameplate is located on the top cover of the pump.
The extra nameplate supplied with the pump should be affixed at
the installation site.

Note
Note
When pumping liquids with a density and/or a
kinematic viscosity higher than the values stated
above, use motors with correspondingly higher
outputs.

Warning
Depending on the installation type, the sound
pressure level of the pump may exceed 70 dB(A).
When working nearby such an installation in
operation, hearing protecting devices must be
used.
