General description of the performance ranges, motors and materials for all ranges of construction
    |
All ranges of construction are chemical resistant and are especially suited for the transmission of highly pure and corrosive media in the following performance range: Volume flow rates up to 500 l/min [30 m3/h] [132 US-Gal/min] for discharge heads up to 40 m [131 ft]. Various designs comply with the European Union ATEX directives for application in explosive atmospheres. Drive motors: High-quality electric motors made in Germany. Pumps are generally equipped with three-phase motors with a performance range of 0.12 to 5.5 kW. Alternating current, explosion proof and pressure-tight encased motors can be supplied on request. Motor details: Standard Motors (stock items): - Three-phase motors: 230/400 V 3ph, 50 Hz, IP 55, insulation-class F or 277/480 V 60 Hz also with PTC thermistor - Alternating current motors: 230 V 1ph, 50/60 Hz, IP 55, insulation-class F - Three-phase motors, spark arrested for for use in potentially explosive atmosphere: EEx e II T3 Special design models (available): - Three-phase motors, spark arrested for for use in potentially explosive atmospheres, flameproof enclosure, EEx de II CT4 - Special voltages and frequencies - 2-, 4- and 8-pole - UL and CSA design - Special protection types- (e.g. IP 65) - High temperature designs - Special insulation classes (e.g. tropical insulations) - Multi area voltage (e.g. 220-290 / 380-500 V 50 Hz; 220-332 / 380-575 V 60 Hz.) Additional designs upon enquiry.
