Product Information Pump with magnetic drive A.u.K. Müller Solenoid valves Control valves Special valves and systems A. u. K. Müller GmbH & Co. KG Dresdener Str. 162 D-40595 Düsseldorf/Germany e-mail: [email protected] Internet: www.akmueller.de Characteristics Low running noise Suitable for food and hot water appliances Impeller with PTFE or ceramic sliding ring Suitable for dry run (max. 5 minutes) Basic interference suppression integrated into motor Optional: PTC - Overload protection according to EN 60335-1 The pumps, series 41.008.200/~201/~202 are designed to increase pressure to enable a higher flow rate and improved dispense accuracy. They are ideally suited for applications where a low water level in a boiler causes an insufficient flow rate through traditional boiler dispense valves. Use of the pump allows for flexible siting of dispense valves inside the machine, including up to 3 meter above the water level in the boiler. Hot / cold drink dispensers Increase output pressure on low water level boilers Tank or boiler draining Possible approvals Approved versions available on request: NSF 169 Others on request The pumps body housing is suitable for use with hot water Varying the voltage supplied to the pump will change its speed and thus vary the flow rate output. Typical performance curves 41.008.201 600 The impeller is driven by a non-contact magnetic connection which avoids the use of additional seals preventing potential leak paths. The impeller is supported as a slide bearing on a stationary sealing disc. The pump series distinguish in the material pairing that differ in terms of lifetime, dry running characteristics and mechanical stability. In the series 41.008.200, a stainless steel sealing disc with PTFE sliding ring is applied. The series 41.008.201 is equipped with the ceramic/ceramic material pairing, leading to an improved dry running performance and service life in hot water applications. In the series 41.008.202, the material pairing stainless steel with anti-wear coating/ ceramic exhibits also an improved lifetime next to mechanical stability. © copyright A.u.K.

For this purpose an overcurrent protection should be provided on the system electronics to prevent overheating...

Pump with magnetic drive Pump with thermal motor protection An additional circuit board located on the terminal side of the motor prevented by means of a PTC a temperature critical current of the motor and therefore satisfies the requirements of EN 60335-1. The thermal overload of the motor, caused by a blocked motor for example, will effectively be avoided. The electrical connection of the motor is even more simplified by a RAST 2.5 connector. © copyright A.u.K. Muller, technical changes reserved
