Explosion-proof design with ATEX certification
The DNA-EX series is used for pumping biological liquids and wastewater. Its large free passage for solids makes it ideal for treatment plants, public and private sewer systems, and the livestock industry.
Pumps in this series can be used in all hazardous areas, in accordance with the certificate available on request.
Features
All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, ensures a long service life.
Advantages of DNA-EX pumps
The DNA-EX sewage pump is the ideal solution for anyone looking for a professional product for use at home or in a small business. The DNA-EX sewage pump’s large free passage is the best alternative to pumps with a grinder, which often becomes clogged and causes operating problems for the user. The large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-term operation without intervention. The open six-vane Vortex impellers handle even fibrous sewage exceptionally well, whereas grinders can wind fibres around their blades. Grinder blades quickly become blunt in sewage, acting like wedges and blocking the pump. Sewage pumps with such a large free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls are suitable for years of operation in raw domestic wastewater. The connection flanges allow installation with any coupling feet with DN50-80 PN10 bolt holes.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or the site layout may sometimes require a more powerful pump.
Controls
The DNA-EX sewage pump is available in two power supply versions: single-phase and three-phase. Floats are available as separate accessories and are connected to a special EMX-EX barrier (relay in a control cabinet). To control DNA-EX pumps (except versions with a built-in float), we recommend the simple M121 controllers M121 (230 V); suitable control cabinets that meet ATEX requirements can also be used.
Installation methods
Thanks to the DN flange, DNA-EX pumps are often installed on guide rails in domestic, municipal, and network sewage pumping stations, as well as stormwater pumping stations. When used with a suitable hose connection (an elbow ending in a plain end), they become portable pumps for drainage and handling liquids with a high solids content (gravel, sand, waste). The DNA-EX sewage pump can be used to water a garden with rainwater, drain a flooded garage or basement, or pump water from a pond or ditch into another tank. DNA-EX pumps have stable feet that extend from the pump body, allowing them to stand on level ground with sufficient clearance beneath the body for water intake.
Like all DRENO sewage pumps, DNA pumps also come with a standard 10-meter power cable. They work perfectly with DRENO guide rails: DUTY50, DUTY 65, DUTY 80 and B5.
