Explosion-proof design with ATEX certification
The DNA-EX series is used for pumping biological liquids and sewage. 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 main 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 product lifespan.
Advantages of DNA-EX pumps
The DNA-EX sewage pump is the ideal solution for anyone looking for a professional product for home or small business use. The DNA-EX sewage pump's large free passage makes it the best alternative to pumps with macerators, which often clog and cause operating difficulties. A large free passage beneath the impeller for solids measuring 45 to 80 mm (depending on the model) ensures long-term operation without the need for intervention. Open six-vane Vortex impellers handle even fibrous sewage exceptionally well, while macerators act like winding devices. Macerator blades, which quickly become blunt in sewage, act like wedges and block the pump. Sewage pumps with such a large free passage beneath the impeller do not have these drawbacks. The impeller's thick walls ensure years of operation in raw domestic sewage. The connection flanges allow installation with any guide rail coupling feet with holes to DN50-80 PN10.
When selecting a pump, check the specifications of the available pipeline, as the diameter of the discharge pipe or the terrain may sometimes require a more powerful pump.
Controls
The DNA-EX wastewater pump is available in two power supply versions: single-phase and three-phase. Floats are available as separate accessories and connect to a dedicated EMX-EX barrier (a relay in the control panel). To control DNA-EX pump operation (except for versions with a built-in float), we recommend simple M121 controllers M121 (230 V). Suitable control panels that meet ATEX requirements can also be used.
Installation methods
Thanks to the DN flange, DNA-EX pumps are often installed on coupling feet in domestic, municipal and network wastewater pumping stations, as well as stormwater pumping stations. With a suitable hose connection (an elbow with a plain end), they become portable pumps for drainage and for pumping liquids with a high solids content (gravel, sand, debris). A DNA-EX wastewater pump can be used to water the garden with rainwater, drain a flooded garage or basement, or pump water from a pond or ditch into another tank. DNA-EX pumps have sturdy feet that protrude from the pump body, allowing them to stand on a level surface while providing sufficient clearance beneath the body for water intake.
Like all DRENO wastewater pumps, DNA pumps come standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
