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 wastewater 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 main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in an oil chamber, ensures 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 home or small business use. The DNA-EX sewage pump’s free passage makes it the best alternative to pumps with macerators, which often clog and cause operational problems for users. The 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 the need for intervention. Open six-vane Vortex impellers handle even fibrous sewage contents with ease, while macerators act like winding reels. 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 are designed to withstand years of operation in raw domestic sewage. The connection flanges allow installation with any coupling feet with holes to DN50-80 PN10 dimensions.
When selecting a pump, check the specifications of the available pipeline, as the diameter of the discharge pipe or the 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 panel). To control DNA-EX pumps (except models with a built-in float), we recommend the simple M121 controllers M121 (230 V); suitable control panels can also be used to ensure compliance with ATEX requirements.
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. With a suitable hose connection (an elbow with a plain end), they can be used as portable drainage pumps for liquids containing large amounts of solids (gravel, sand, debris). 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, the DNA models come standard with a 10-meter power cable. They work perfectly with DRENO guide rails: DUTY50, DUTY 65, DUTY 80 and B5.
