Tailor-made Slurry Pumping Solutions

Thursday, November 23rd, 2017 von admin

After the took over of almost complete solid matter pump programme for abrasive and abrasive/corrosive media from the insolvent company Arthur Habermann the Aurum Pumpen GmbH has set itself the objective of improving both the design and the materials engineering of its pump series. In initial orders for a major customer, newly designed pump solutions have already been developed, implemented and built.

Because the Aurum-Habermann heavy duty pumps are true solids handling pumps in terms of impeller geometry and design, these cannot conform to the lightweight construction of a standardised pump, and are thus individually adapted to requirements. In terms of materials, Aurum supplies the Habermann heat-treated steel qualities that have proven themselves over decades.

Simplified servicing in beneficiation plant

Thursday, November 16th, 2017 von admin

Until January 2017, a copper beneficiation plant in Zambia was using pumps from six different manufacturers, including units from Netzsch. Attributable to the large number of different models, this resulted in a steadily growing inventory of similar spare parts and maintenance procedures. Thereby, the effort and costs for necessary maintenance of the pumps were constantly increasing as a result. Following a thorough review of the reliability and service life of its pumps, the plant operator decided to simplify its spare parts inventory and maintenance – and only use pumps from Netzsch as a single supplier.

The Zambian company replaced 36 pumps for polymer applications and saved 1 million dollars by reducing its spare parts inventory as well.

Improvements and cost reduction of chamber filter press feed

Wednesday, November 15th, 2017 von admin

Coal continues to be an important raw material. Speci­fically in Poland, the majority of energy is generated by converting coal into electricity. Mining operations have to use the most modern technology in order for this process to run as efficiently as possible. The Pniówek Processing Plant operates 9 chamber filter presses with 570 m3 of filtration area each.

Before modernization, 2 centrifugal pumps were used for press feeding which were consuming 560,000 kWh/year of energy. Added to this were repair costs of approxi­mately 27,000 Euros annually. In 2012, the investor decided to change the existing sys­tem and reassess the requirements and objectives of the filter press feeding modernization project, most important of which was to reduce energy consumption and extend intervals between repairs.

Wilden: 13 mm (½”) Clamped Metal Pump

Friday, September 1st, 2017 von admin

This 13 mm (½”) clamped metal AODD pump PS1 is equipped with the energy-efficient Pro-Flo Shift Air Distribution System and its clamped configuration allows for easier maintenance, diaphragm replacement and cleaning.

The footprint of this AODD pump matches that of the Wilden PX1, which enables direct replacement of a PX1 with no repiping necessary. With less components and 7% more efficient than the PX1, the backward capability of the PS1 makes it an easy way to enhance and upgrade existing pump performance.

6ʺ solids handling pump

The dry self-priming pumps of the BA series are now also available in stainless steel 316. These pumps are made for a variety of industrial applications, particularly with corrosive environments such as offshore or mining which demand high performance materials.

The stainless steel casting parts are typically available from stock for the most popular BA models. This allows the stainless steel pumps to be quickly assembled with a diesel or electric motor in a sound attenuated canopy or in an open frame.

Andritz: Dewatering flooded mine tunnels in South Africa

Thursday, July 17th, 2014 von admin

South Africa is currently dealing with the problem of acid water because underneath the old gold mining city of Johannesburg is a lake which contains heavily contaminated water, which spreads horizontally and vertically into the abandoned pits of the former gold mines.  Meanwhile, the water line has reached a critically high level, as determined by the specialists from Andritz Ritz, which was given the first order to drain the mine water in 2010. The execution of the project was delayed by four years however, and it was only in spring 2014 that two powerful submersible motor pumps were installed in the middle of Johannesburg city centre, in the so-called “Central Basin”, with each pump capable of bringing 1,500 m³/h of water to the surface.
