Explosion-proof design with ATEX certification
The DNA-EX series is used to pump biological fluids and sewage. Its large free passage for solids makes it ideal for wastewater treatment plants, public and private sewer systems, and the animal husbandry 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, located in an oil chamber, ensures a long product 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 free passage is the best alternative to pumps with a macerator, which often clogs and causes operating difficulties. A large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-lasting operation without intervention. The open six-vane Vortex impellers handle even fibrous sewage with ease, while macerators tend to wind fibers around their blades. Macerator blades quickly become blunt in sewage and act like wedges, 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 untreated domestic sewage. The connection flanges allow installation with any guide rail coupling foot with DN50-80 PN10 mounting holes.
When selecting a pump, check the parameters of the available pipeline, as the discharge pipe diameter or terrain geometry 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 connect to the dedicated EMX-EX barrier (a relay in the 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 rail couplings in domestic, municipal, network sewage and stormwater pumping stations. When used with a suitable hose connection (an elbow ending in a plain end), they become portable pumps for drainage and pumping liquids with a high solids content (gravel, sand, debris). 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 stable feet extending from the pump body, allowing them to stand on level ground with sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes with a 10-meter power cable as standard. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
