Rev­o­lu­tion­ary air-op­er­ated dou­ble di­aphragm pumps

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

The air-op­er­ated dou­ble di­aphragm (AODD) pump is one of most ver­sa­tile and com­monly used pumps in the world.

These pumps are gen­er­ally sim­ple to op­er­ate and of­fer good f lex­i­bil­ity for a wide range of in­dus­trial ap­pli­ca­tions.

How­ever, they also have a rep­u­ta­tion for high air/en­ergy con­sump­tion, high main­te­nance costs, down­time, high noise, as well as com­plex­ity when it comes to ser­vic­ing or or­der­ing re­place­ment parts.

Al­bin, a leading French man­u­fac­turer of hose, gear and lobe pumps, has de­vel­oped a rev­o­lu­tion­ary AODD pump that – com­pared to generic brands – of­fers up to 70 per cent lower pul­sa­tion, lower en­ergy con­sump­tion/bet­ter ef­fi­cien­cies, lower noise out­put, and three to five times longer oper­a­tion time be­tween ser­vice in­ter­vals.

All of these im­prove­ments re­sult in sig­nif­i­cant op­er­a­tional and main­te­nance cost sav­ings to the end user.

With the Al­bin AD pump, en­ergy use is re­duced by means of a re­duc­tion of fric­tion and cur­rent losses through a cen­tral f low path and unique air valve de­sign. The re­sults are lower costs through heav­ily re­duced en­ergy con­sump­tion and, as a con­se­quence, lower en­vi­ron­men­tal im­pact.

The re­duced fric­tion and cur­rent losses also re­duce pul­sa­tion. In­de­pen­dent tests at the Tech­ni­cal Univer­sity of Stock­holm in Swe­den have shown that AODD pump users can re­duce their com­pressed air con­sump­tion by 30-45 per cent. The pumps are de­signed with a min­i­mum of mov­ing parts and all main parts can be changed with­out dis­con­nect­ing the pump. The patented di­aphragm sus­pen­sion and air valve de­sign of the pump has proven though tri­als that di­aphragm life is gen­er­ally in­creased up to five times.

The com­pact outer mea­sure­ments and ca­pa­bil­ity to in­stall the pump upside down, side­ways or ver­ti­cally pro­vides ex­cel­lent f lex­i­bil­ity dur­ing in­stal­la­tion and set up.­quiry #D131205
