New coating for aseptic geared motors is corrosion and scratch resistant

17 January 2018

SEW Eurodrive has launched a new innovative coating for aseptic geared motors that provides protection against chipping, flaking, scratching and corrosion.

The new XCO package is an alternative to stainless steel and is designed for use in industries where chipping or flaking paint on drive components poses a contamination risk to end products.

The XCO drive package is SEW’s new eXtreme Corrosion Option and is a tin-nickel surface coating that has the appearance of stainless steel. Due to its hardness, of approximately 645HV, the surface is scratch resistant and will not come off as a result of wear, flaking or chipping, a potential problem with conventionally painted units.

Designed for use in industries where equipment may be subject to frequent wash-downs, the XCO drive package is approved for short-time contact with food according to 1935/2004/EC. Also, in addition to the surface protection with high corrosion resistance and a scratch resistant surface, the XCO package includes, stainless steel screws, IS plug connectors, stainless steel nameplate and a pressure compensation membrane.

The new XCO drive package has been designed for use in industries such as food manufacture, bakeries, confectionary, cheese and dairy products, drink manufacture, bottling plants, fish and meat processing and pharmaceuticals.

Currently available with the XCO drive package are the R and RF series helical gear units up to 450Nm and the S, SF, SA, SAF, SH, SHF and ST series helical worm gear units up to 295Nm. Additional gear unit types will be added shortly to expand customer options even further.
