Accumulator
Pressure losses may occur in the piping
downstream of the pressure booster system as a
result of losses due to leakage. The accumulator
serves to compensate for pressure losses and
minimises the frequency of starts of the pressure
booster system.
Certificate of decontamination
A certificate of decontamination is enclosed by
the customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Dry running protection
Dry running protection devices prevent the pump
from being operated without the fluid to be
handled, which would result in pump damage.
Energy-saving mode
Setting designed to avoid the energetically
inefficient operation of a pump at minimum water
consumption.
Filling the accumulator
Function to fill a (discharge-side) accumulator; it
prevents pump sets from starting if only a very
small amount of water (e.g. caused by leakage)
is required.
IE3
Efficiency class to IEC 60034-30: 3 = Premium
Efficiency (IE = International Efficiency)
Manual mode
Direct operation on the power supply network,
independently of the control unit.
Switchgear and controlgear assembly
Control cabinet with one or several control units /
switchgears and electrical equipment.
