Get­ting the right fil­ter noz­zles can be chal­leng­ing

DEMM Engineering & Manufacturing - - MAINTENANCE MATTERS -

For main­te­nance en­gi­neers keep­ing wa­ter fil­tra­tion sys­tems in good work­ing or­der can be dif­fi­cult, par­tic­u­larly in the case of older sys­tems. Not only is there a wide di­ver­sity of fil­tra­tion sys­tems in use, there is also sub­stan­tial vari­a­tions in the types of fil­ter noz­zles used.

“In our work we come across mas­sive dif­fer­ences in the types of fil­ter noz­zles in use,” said Graeme Cooper, Man­ag­ing Direc­tor of Tecpro Australia. “There are many vari­a­tions in slot widths, thread and stem sizes as well as the ma­te­rial the noz­zles are made from. When you’re re­plac­ing them, it’s vi­tal to have a close match for their di­men­sions and also to en­sure the fab­ri­ca­tion is suit­able for lo­cal con­di­tions.”

Cooper said the ma­te­ri­als used in the con­struc­tion of fil­ter noz­zles af­fect how well they per­form in dif­fer­ent op­er­at­ing tem­per­a­tures, and how well they with­stand chem­i­cals and gen­eral wear and tear.

“Our range in­cludes fil­ter noz­zles con­structed from stain­less steel and stan­dard polypropy­lene, as well as dif­fer­ent spe­cialised for­mu­la­tions to of­fer in­creased strength, dura­bil­ity and chem­i­cal re­sis­tance. Th­ese in­clude glass-filled polypropy­lene, min­eral-filled polypropy­lene and polyvinyli­dene­flouride, or PVDF as it’s known,” said Cooper.

“The ILMAP fil­ter noz­zles are pre­ci­sion­made and are highly re­garded for the re­li­able di­men­sional ac­cu­racy of their slot sizes, which pre­vents the pas­sage of par­ti­cles,” said Cooper. “Of course get­ting the best out­come starts with hav­ing ex­pert ad­vice to help you choose the model that will ca­pa­bly deal with the de­mands placed on your sys­tem.” www.demm.co.nz/reader en­quiry #150530a.
