All series are resistant to chemicals and are particularly suitable for pumping highly pure and aggressive media in the following performance range:

• Volume flows up to 500 l/min [30 m3/h] [132 US-Gal/min]
• for heads up to 40 m [131 ft].

Different versions are approved for use in Ex areas (ATEX).
Drive motors High-quality electric motors from German production. All pumps are equipped as standard with three-phase motors in a power range from 0.12 to 5.5 kW. AC, explosion-proof and flameproof motors are also available.
