WILO will be showing an extensive product range for water supply as well as sewage disposal and purification at the IFAT ENTSORGA 2010, the leading world-wide trade fair for the water, sewage, waste and raw material industry in Munich this September.
The company is one of the leading manufacturers of pumps and pumping systems for heating, cooling and air-conditioning technology, for water supply and drainage and sewage. Wilo is represented by almost 70 subsidiaries all over the world and employs more than 6,000 people worldwide.
A sewage pump with a new impeller shape will be the centre of attention of the Wilo exhibits at the show. This new development takes into account that the higher the amount of the solids in sewage, that sewage becomes more and more aggressive. To address this, the impeller is designed for use in untreated sewage and combines a lack of susceptibility to clogging - similar to vortex impellers - with high efficiency which corresponds approximately to that of single-channel impellers.
A key characteristic of the construction of the new impeller is the flow optimised design that prevents pointed geometries to which solids can stick or where they can settle. In addition, flow grooves have installed in the suction range to provide slight turbulences, that counteract possible deposit build up. The new pump series is available with the nominal diameters DN100 to DN350. Volume flows of more than 600 l/s or delivery heads up to 60 m Hmax can be realised.
"Sewage pumps equipped with the new impeller can achieve a hydraulic efficiency of up to 81 % and set a new standard for energy-efficiency and efficient sewage disposal," said the manufacturer. "The symmetric construction and feed channels and flow grooves arranged in the suction opening, prevent vibrations. This is a further advantage because weight and fluid flow are homogenously distributed and the fluid is led in the discharge channels. In addition, the impeller is particularly vibration-free due to its symmetric and cylindrical construction."
In addition, WILO will be exhibiting highly innovative slow running submersible mixers with highly power saving, asynchronous motors which comply with the new European energy efficiency class IE3 for not immersed asynchronous motors. The power consumption decreases by around 90% when compared to standard units.
Taking into consideration the fact that submersible mixers operate for up to 24 hours every day in wastewater treatment plants, being one of the largest energy consumers, it's easy to see how significant cost savings can be achieved. Wastewater treatment plant technology from Wilo offers huge potential for power saving and are amongst the most efficient systems on the market due to the 'wing' shape of the mixers and highly efficient gearing which is optimised to minimise the use of energy. It is also possible to retrofit existing mixers with IE3 motors.
Wilo has also been informed that "Wilo-Ceram CT" coating which is used for submersible-motor pumps for potable water abstraction, has now been KTW approved. The surfaces of pump and motor housings, as well as impellers, which are equipped with this highly effective two-component-coating have significantly longer service lives. The efficiency of the pumps can be increased by approximately 2% so that entire life cycle costs can now be reduced.
