Explosion-proof design with ATEX certification
The DNA-EX series is used for pumping biological fluids 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, located in the 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 home or small business use. The DNA-EX sewage pump’s free passage is the best alternative to pumps with a macerator, which often clogs and causes operating problems for the user. The large free passage beneath the impeller allows solids measuring 45 to 80 mm to pass through (depending on the model), ensuring long-lasting operation without the need for intervention. The open six-vane Vortex impellers handle even fibrous sewage contents with ease, while macerators act like winding reels. 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 are free from these drawbacks. The impeller’s thick walls ensure years of operation in raw domestic wastewater. The connection flanges allow installation with any coupling feet with holes to DN50-80 PN10 specifications.
When selecting a pump, check the parameters of the available pipeline, as the diameter of the discharge pipe 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 connect to the special EMX-EX barrier (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 can also be used to ensure compliance with ATEX requirements.
Installation methods
Thanks to the DN flange, DNA-EX pumps are often installed on coupling feet in residential, municipal, network and stormwater sewage pumping stations. With a suitable hose connection (an elbow with a plain end), they become portable drainage pumps for handling 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 into another tank. DNA-EX pumps have sturdy feet extending from the pump body, allowing them to stand on level ground with enough clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
