ABEL's electromechanical diaphragm pump has just received a European patent.
tively with the EM. The traditional low overall efficiency and c o r r e s p o n d i n g l y high e n e r g y input performance of air-operated m e m b r a n e p u m p s has been improved greatly by a factor of up to seven times. By installing an electric drive, ABEl, has revealed a potential savings in some cases of DM75 000.
In the EM, the n u m b e r of wear parts has b e e n reduced significantly to approximately 5% of the p u m p value. This is a clear advantage over eccentric screw pumps, w h e r e the figure is nearer 70%, i n d u c i n g high and u n p r e d i c t a b l e o p e r a t i n g costs. A further important benefit of the EM is its run dry capability.
D e v e l o p m e n t of the EM range will continue in logical stages. In the first haft of this year, a CIP/SIP-cleanable p u m p will be introduced. Flap valves will be offered as an option to allow the smooth and obstruction-free transfer of non-homogeneous media.
All the classic advantages of diaphragm p u m p t e c h n o l o g y can be found in the EM pumps: high volumetric efficiency, good m e d i u m compatibility due to the wide choice of materials available, the use of frequency converters for easy control and high abrasion resistance.
