SB Pumps and Valves has released its
highly efficient range of Amarex KRT
submersible motor pumps for han-
dling municipal and industrial waste water
in an effective and cost effective manner.
Taking their cue from previous models,
KSB engineers have further improved the
operating reliability and hydraulic efficien-
cy to squeeze more out of the pump. By
focusing on the typical operating ranges
of waste water pumping stations the de-
velopers have adjusted the impellers’ free
passages to not only comply with the ap-
plicable standard, but also to allow the
pumps to offer as broad a range of appli-
cations as possible.
Available with four different improved impel-
ler types, the submersible motor pumps can
achieve a maximum flow rate of 10 080 m³
per hour and a head of 120 m. With 850 kW
of power on tap, it offers the highest standard
motor power available on the market today.
Despite this, KSB electric drives for these
modern submersible motor pumps are ul-
tra-efficient. Depending on a system’s load
profile, users can choose a highly efficient
motor variant which corresponds to the IE3
efficiency level for standardised motors in
accordance with the IEC-60034-30 stan-
dard. Such motors are particularly interesting
for powerful pumps with a high start-up fre-
quency. Two bi-directional mechanical seals
reliably protect the motor space against in-
gress of water.
A chamber filled with environmentally friend-
ly oil ensures cooling and lubrication of the
mechanical seals even when gas-laden flu-
ids have to be pumped. Generously dimen-
sioned ball bearings sealed for life support
the stainless steel shaft with a special focus
also being placed on the design of the cable
gland. Individual conductors stripped, tinned
and sealed in resin ensure that the cable
gland is absolutely watertight even in the
event of damage to the cable sheath or the
insulation. This also effectively
protects the pump from short
circuits.
To ensure that the pumps
can be easily dismantled
even after years of oper-
ation under tough condi-
tions, all wetted screwed
connections are made
of stainless steel.
For transporting acid
waste water, too, KSB
also supplies pumps
made from high-grade
stainless and acid-re-
sistant duplex
steel.
