1.5. Technical terms
Various technical terms are used in this operating and
maintenance manual.
Dry run
The product is running at full speed, however, there is no
liquid to be pumped. A dry run is to be strictly avoided. If
necessary, a safety device must be installed.
“wet” installation type
This installation type requires the product to be immersed
in the pumped fluid. It is completely surrounded by the
pumped fluid. Please observe the values for the maximum
submersion depth and the minimum water coverage.
“dry” installation type
In this installation type, the product is installed dry, i.e. the
pumped fluid is delivered to and discharged via a pipeline
system. The product is not immersed in the pumped fluid.
Please note that the surfaces of the product become very
hot!
“transportable” installation type
With this installation type the product is equipped with a
pedestal. It can be installed and operated at any location.
Please observe the values for the maximum submersion
depth and the minimum water coverage, and remember
that the surfaces of the product become very hot.
“S1” operating mode (continuous operation)
At the rated load, a constant temperature is reached that
does not increase even in prolonged operation. The oper-
ating equipment can operate uninterruptedly at the rated
load without exceeding the maximum permissible tem-
perature.
Operating mode “S3” (intermittent operation):
For this operating mode, after the abbreviation, the per-
cent duty cycle is displayed, as well as the cycle duration if
it is greater than 10 minutes. For example S3 40% means
the pump can operate continuously for 40% (24 minutes)
of one hour, and must then pause for 36 minutes.
Low Level Lockout
The low level lockout is designed to automatically shut
down the product if the water level falls below the min-
imum water coverage value of the product. This is made
possible by installing a float switch.
Level control
The level control is designed to switch the product on or
off depending on the water level. This is made possible by
installing a float switch.
