Visit product website DATA SHEET Type 2505 Socket for 10 mm for Bürkert Solenoid Valves 1000011780 | Standard | EU | en | 201912 | 09 Micro diaphragm pump for continuous pumping
- self-priming
- nearly pulsation free
- for continuous pump applications
- diaphragm pump The Burkert series 7604 is a unique, selfpriming, adjustable, diaphragm pump with a long service life and quiet operation that is ideally qualified for aggr essive media. The pump is perfectly suited for continuous liquid low flow applications. Variations in flow rate are achieved by simply varying the fre- quency input. With a maximum frequency input of about
40 Hz,
free. Perfluorelastomer seals and a PEEK body are the only wett ed parts, allowing the pump to be used for a wide range of aggressive fluids, organic and inorganic solvents and other difficult to handle media. The compact design (only 11 mm wide) allows for ease of mounting with standard bodies designed for surface mount (manifold) or tube connections. The low power consumption allows the device t o be easily incorporated into mobile devices, and virtually eliminates any heat transfer passed from the actuator to the fluid. „Manufactured by Burkert“ ensures the user the same high quality pr oducts and proven reliability they have depended on in today’s innovative market. Product variants described in the data sheet may differ from the product presentation and description. Type descriptionCan be combined with Type 7604 © Christian Bürkert GmbH & Co.
