PUMPS
Beside the pumps with a flow rate between
20 and 140m³/h, there is a membrane pump
available which can process sludge with a
solid content of up to 80%.
All pumps are driven by Hatz diesel-engines
with either one or two cylinders which work
reliably even under adverse conditions, it
claimed.
The AP- and AQ-series are for agricultural
use, and the S-series for industrial.
Hatz
said
the
sustainability
and
environmental compatibility of its products
was part of the company philosophy.
All B- and D-series engines are produced
in the specification which meets the strict
emission standards of the EPA (Environmental
Protection Agency) in the US, even if the
standard in the destination country is not
applicable.
Hatz added that the multi-cylinder engines
of the L- and M-series also met all required
emissions standards and
are partially supplied
with
exhaust
gas
recirculation to reduce
nitrous oxides.
From this year, the three-and
four-cylinder engines will be
available with diesel particulate
filters (DPF).
UK firm Selwood said it was
“bringing low emission engines to
the high head pump market” with
the introduction of its H200 pump,
powered by a Stage III/Tier 4
Interim Volvo D16 engine.
The engine uses a DPF and
a diesel oxidation catalyst in
combination with selective
catalytic reduction to conform to the current
emissions regulations, which apply in Europe
and the US.
The H200, with a pumping capacity of more
than 950m³/hr, joins the already launched
H100 and H150 units in the new high head
range.
The H150 is a heavy duty automatic self
priming pump designed for high head
applications, with flow rates up to 460m³/h,
total heads of 124m and solids handling of
38mm.
LONGER LIFE
Pam Meyer, equipment sales manager
at Subaru Industrial Power Products, also
considers that a longer life for pumps is
important, and she pointed out that
performing preventative maintenance helped
prevent pump downtime.
She said that each day should start with a
pump inspection. Among the most important
daily checks is the quality and level of engine
oil.
Oil that’s contaminated can cause serious
problems and decrease the life of an engine,
likewise if there’s an insufficient amount of it.
Change the oil or add if necessary to reach the
level as per manufacturer’s recommendation,
she said.
The fuel level should be checked as well,
while Meyer recommended looking for any
evidence of fuel or oil leaks. If a fluid is
dripping, inspect the area for any parts that
may need to be tightened or replaced.
Cleaning or possibly changing the air filter is
another important practice that can prevent
significant damage down the pipeline, said
Meyer.
Inspecting the condition of the hoses
regularly is another suggestion. In addition
to daily checks, a pump requires other
maintenance checks and services. Meyer said
that while those don’t need to be done daily,
they are crucial to the pump’s life and should
be on a regular schedule. Generally, quality
pump engines can operate up to 2,500 hours,
she said.

New rental models for Poland
Ramirent, a leading European equipment rental company with 325 customer centres in
11 countries, has just purchased 50 Atlas Copco WEDA on-site submersible pumps for its
regional branch in Poland.
The order is part of a total of 400 new pumps that will replace older equipment.
Ramirent’s first order of 50 Atlas Copco WEDA pumps consists of 19 WEDA 10, 19 WEDA 30
and 12 WEDA 40 pumps. Before the end of 2014, Ramirent plans to order a total of 400 new
pumps, normally to be fulfilled by two suppliers, to update its regional fleet of 800 electric
and petrol-driven submersible pumps.
Ramirent in Poland already uses Atlas Copco compressors and generators in its rental fleet.
In 2011, the Slovakian branch placed a significant order of WEDA pumps as well. That proved
a deciding factor in making the switch to WEDA pumps in Poland.
Konrad Murawko, fleet manager at Ramirent, said, “The main advantage of Atlas Copco
equipment is quality. We have been using Atlas Copco pumps in other countries, so we
have first hand experience of the durability and long lifetime of these pumps in harsh
environments.”
Murawko added that Ramirent “prefers to work with reliable and strong suppliers that do
not have their own rental activities”.
Each pump will be delivered with a Storz discharge coupling, built-in float switch and an
additional rope to prevent customers pulling out cables when manoeuvring the pump.
Michal Goral, sales manager Poland with Atlas Copco Portable Energy, said, “Listening to
your customers to understand their needs is key to building a long relationship with them.
With these customisations we are able to deliver the pumping solutions that meet Ramirent’s
exact requirements.”
Murawko added, “We value the professional support from the local and regional Atlas
Copco customer centres and their willingness to co-operate with us. In the end, quality is not
just about the product itself, but also about the organisation behind it.”
