is made of ultra-hard silicon carbide.The pump is designed for
longevity andTsurumi said it could run all day, and is protected
by a continuously cooled and lubricated mechanical seal by a
patentedoil-lifter and a thermal overload switch.
The company launched itsnewKTDpumps earlier this year
– including the KTD22.0 and KTD33.0models.The KTD

Per Rehn,
“Reliability is
the key thing.”
The Tsurumi
GPN415 has a
15kWmotor.
The newmodel is available in seven variants from 1.5 to 3.7
kW at 400V.They pump430 to1,440 litres/minute, depending
on the model, and create a maximum lifting head of 36.5 m.
The discharge of the pump canbe adjusted either horizontally or
vertically.Tsurumi said thishelped tokeep thepump standing
in the direction of discharge, although the pump can run in
any position.
It said that, in contrast to other models on the market,
electrodes determined the level of control in the pump,
increasing reliabilitywithnomoving parts.
This is said to be an advantage on a construction site if the
ground is not flat, and the company said electrode
type sensors were more reliable and long lasting,
reducing the potential for damage.
The automatic pump can be left unattended,
saidTsurumi, saving substantial operating costs.
The pump starts when the sensor identifies
the correct water level and stops as soon as the
water level drops below a certain point. The user
can manually adjust the level required in order to
maintain the amount of water desired.
Tsurumi is a universal contractor pump manufacturer for
dirty water solutions such as rain water, sandy water and
groundwater.
Water contaminated with granular solids up to 8.5mm in
diameter canbe pumped away using theKTZE, it said.
The pump’s housing is made of cast iron and is said to be
resilient, with the semi-open vortex impellermade of chromium
