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.
Specifications
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 product 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 macerators, which often clog and cause operational difficulties. 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 content with ease, while macerators act like winding mechanisms. Macerator 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 ensure years of operation in raw domestic sewage. The connection flanges allow installation with any coupling feet with holes to DN50-80 PN10.
When selecting a pump, check the specifications of the available piping, as the discharge pipe diameter or site layout may sometimes require greater power.
Control
The DNA-EX sewage pump is available in two power supply versions: single-phase and three-phase. Float switches are available as separate accessories and connect to a dedicated EMX-EX barrier (relay in the control cabinet). To control DNA-EX pumps (except versions with a built-in float switch), we recommend 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 coupling feet in domestic, municipal and network sewage pumping stations, as well as stormwater pumping stations. With a suitable hose connection (an elbow with a plain end), the pump can be used as a portable dewatering pump and to handle liquids with a high solids content (gravel, sand, waste). The DNA-EX sewage pump can be used to water the garden with rainwater, drain a flooded garage or basement, and pump water from a pond or ditch to another tank. DNA-EX pumps have sturdy feet that extend from the pump housing, allowing them to stand on a level surface while providing sufficient clearance beneath the housing for water intake.
Like all DRENO sewage pumps, DNA pumps come standard with a 10 m power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
