We see from your search that you're looking for information on the term "Diaphragm Pump",
and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest.
Let me be your guide.
Start with
the news release Rotary membrane pumps have unique operation from
Schwarzer Precision, which we summarised at the time by saying "SP 027 RO's unique operating principle of a wobbling disc connected with two or more diaphragms makes it a very compact pump with an ideal performance for inflation of all kinds of
cuffs or cushions".
A few weeks before,
we featured the news release SP 600 EC miniature diaphragm pump is updated from
Schwarzer Precision: "The new low-noise and low-vibration SP 600 EC works oil- and maintenance-free and has an extremely long service life, and variable fixation options ensure a high flexibility of mounting possibilities".
In February 2007, we covered the news from KNF Flodos
concerning its Liquiport pumps
- take a look at KNF Flodos pumps used for semiconductor technology
which says: "Liquiport pumps from KNF Flodos are being used by a leading provider of lithography systems to develop instruments for the fabrication of state-of-the-art chips and integrated circuits".
Take a look also at the news release from KNF Neuberger, The NMP 850 micro diaphragm pump,
as well as Miniature diaphragm pumps get smaller and better from Hargraves Technology,
and Self-cleaning dry vacuum system is programmable from Welch Rietschle Thomas.
