Self-cleaning tank inserts for waste water tanks

Thursday, February 8th, 2018 von admin

At this year’s Ifat trade fair in Munich, KSB is presenting its ready-to-install self-cleaning Amaclean tank insert. Amaclean decreases the amount of stagnant water in the pump sump and reduces the need for maintenance and cleaning.

In combination with select impeller types featuring in the waste water pumps used, this tank insert eliminates the need for flushing valves. Amaclean’s patented design and gel-coated inner surface prevent waste and fibres contained in the waste water from depositing in and at the lower parts of the structure.

Richter expanded RMA series

Thursday, June 29th, 2017 von admin

The RMA series of magnetic drive pumps have been expanded by the new size RMA 4x3x10H. This pump offers increased flow capacity and delivery heights.  The compact pump size with optimized hydraulic system for high flow rates is particularly targeted for North American pump users. The external dimensions per ASME / ANSI and the custom hydraulic system have been developed with interchangeability in mind.  This allows for easy replacement of existing pumps without major installation hassle.

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.

Lewa: Safe pumping of sour crude oil

Thursday, May 7th, 2015 von admin

SauerölpumpeCritical applications of conveying mixtures of acidic hydrocarbon/water to the washing system are a challenge for any pump manufacturer. This was also the case in one recent project Lewa handled in the Emirate of Abu Dhabi. Lewa have designed and supplied 16 pumps to a major construction company in Abu Dhabi specifically designed to handle this critical application. Two processes required to pump

  • liquid hydrocarbons from the flare knock-out drum or the blow-down drum respectively and
  • convey the acidic hydrocarbon/water mixture back into the oil line to the washing system

Since the differences in these two processes are only minor, it was possible to supply 16 mechanically identical pumps of the Ecoflow series, driven by 55 kW electric motors.

Wilden: Stainless steel AODD pump for higher corrosion resistance

Friday, December 19th, 2014 von admin

Wilden_Advanced-FIT_PS830-SSThe new Wilden air-operated double-diaphragm (AODD) pump series 430 and 830 Advanced FIT is produced of 316 stainless steel for higher corrosion resistance in aggressive chemical applications. These sieries have been specifically designed to be direct replacements for existing Wilden 38 mm (1-1/2”) and 51 mm (2”) Advanced pump installations.

“FIT” means

  • bolt-to-bolt and
  • pipe-to-pipe

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.
