Force is the heavier weight class model
of the two pumps produced by Paclite, and
the company said that it was big enough
to allow larger stones and aggregates to be
dewatered.
Gorsun said it was a pump with high output
and a capacity of 72m
3
/h. It has a cast steel
impeller, a 6m flexible shaft and solid size
capacity of 19mm.
The standard delivery with discharge hose
is 10m and there is a 75mm fireman’s quick
release coupling.
Gorsun described the Force model pump
as autonomous, portable and lightweight,
so that it could be used in “a multitude of
applications”.
Meanwhile, Tsurumi’s latest diesel driven
pump, the 4TBA82D135 which was launched
earlier this year, is one of the company’s
biggest models.
Designed to work in the most demanding
dewatering and sewage applications, it offers
a maximum flow of 2,250 litres/m and a
maximum head of 18m.
Described as rugged and fuel efficient, the
pump is said to be suitable for almost any
application, and will be sold in Tsurumi’s
direct sales network in Germany, France,
Spain and Sweden.
Having selected the right pump for the job
in hand, it is important to keep it running so
that when it is needed, it can be put to use
immediately.
With this in mind, Tsurumi has also launched
a life-extending kit.
This is a set of parts for Tsurumi’s KTV and
KTVE range of light-weight aluminiumpumps.
It claimed that after rigorous testing, the new
pump casing, wear ring and protection plate
could give a pump three times longer life.
The company added that the kit was
particularly aimed at tunnel construction
projects where pumps worked in severe
conditions to ensure that on-site water levels
were safe.
Hatz is offering a new line up of clear- and
trash-water, and industrial pumps. All of these
are based on the company's own air-cooled
diesel engines.
Whether for construction sites, disaster
relief or for industrial use, Hatz claimed to
offer a broad spectrum of engine-powered
pumps.
Mainly known for its tailor-made diesel
engine solutions, Hatz now has pumps for all
kinds of use.
It said the basis for the pump systems was
the German-based company’s “robust and
resilient” air-cooled diesel engines, with a
power range from 1.5kW up to 56kW.
The line-up ranges from small and
lightweight one-cylinder engine powered
trash water pumps with a capacity of 20m³/h,
up to clear water pumps with a capacity of
830m³/h powered by a powerful four-cylinder
diesel engine.
Depending on customer requirements, the
pumps can be equipped with a trolley, closed
tubular frame or base frame. Additionally,
there are a variety of other standardised
options available.
The C-series for construction sites is carefully
designed for use in rough conditions.
Solids with a size of up to 40mm can be
processed thanks to robust pump parts and
a pump housing made of aluminium or grey
cast.
Radioactive pumping solution
A Tsurumi pump is being attached to a remotely-operated vehicle (ROV) used in a radioactive
waste clearing project at the specialised Areva reprocessing plant at La Hague in northern
France.
The pump will help to transport radioactive sludge from special silos as part of an eight-
year recovery project.
The La Hague reprocessing plant has the capacity to reprocess almost half the world’s light
reactor spent fuel. The plant is embarking on a major new project to recover and condition
radioactive sludge resulting from the chemical process of spent fuel recycling. This sludge is
contained in several silos.
The project presents a number of technical
challenges. Getting to the sludge itself is
among the hardest as this can only be
attempted through existing openings on
the top of each vessel, and these measure
just 1m across.
To cope with the size restrictions and
yet ensure that every corner of the silo is
reached, a Tsurumi pump connected to an
ROV will travel around the silo pumping
sludge to a downstream treatment unit.
Once lowered into the silo, the ROV will
scour the entire silo and pump out the
sludge to transfer it to the next stage of the
treatment process. Because of the size of
each silo – the largest measures 14m long,
13m wide and 10m deep – the pump is
expected to take two years to complete its
part of the project.
A remote controlled mini-submarine with
the blue Tsurumi pump attached is being
used to remove radioactive sludge from silos
at a nuclear reactor recycling plant in France
Downtime can be avoided by
preventative maintenance,
